The present invention relates to nucleic acids of interest for modulating the microbiome of a host, to vectors encoding said nucleic acids and to methods for modulating the microbiome of a host by delivering said nucleic acids of interest.
Delivery of DNA payloads to express genes of interest in bacterial populations outside of the lab has a lot of applications among which medicine, agriculture, biofueling, cosmetics.
The strategy relies on the delivery of DNA to target bacterial cells in a pure or mixed bacterial population by a viral capsid, by bacterial conjugation or by other methods so that one or several genes of interest will be expressed at a sufficient level to produce a desired effect. The effect can be a direct therapeutic effect on the bacteria itself in or on the host, by killing the bacteria and therefore reducing its colonization level or modifying its ratio compared to other bacteria in the population if multiple species or multiple strains are present; by modifying its genome, by modifying its metabolism or its composition (protein, lipids, sugars, metabolites, RNA, etc.). The effect can also be an indirect effect by leveraging the target bacteria to produce, display or secrete one or multiple molecule(s) such as prophylactic or therapeutic molecule(s) that will have a direct or indirect effect on the host or on other members of the host microbiome.
One of the major concerns with such a strategy is that the exogenous DNA is transferred to progeny cells if the exogenous DNA is stably maintained in the cells in which it is delivered to, or is transferred to other bacteria via other gene transfer mechanism and then stably maintained in these other populations. More generally, the containment of the exogenous DNA payload once delivered in the bacterial populations is a concern.
To solve this issue, the present inventors have herein developed a new strategy that ensures that DNA payloads once delivered in target bacteria cannot replicate in the target bacteria but still express the gene(s) of interest at a level that is enough to exert the expected outcome on the bacteria or on the host, without the need of an antibiotic resistance selection marker on the DNA payload, and without the need of a selection step with an antibiotic.
Plasmids carrying conditional origins of replication have a long history of use by microbiologists as a tool to genetically modify bacterial strains of interest, therefore creating stable genetically modified organisms. They are typically used to select for recombination events between a plasmid carrying such origins and the genome of a bacteria of interest.
Such plasmids carry an antibiotic resistance selection marker and can be introduced into the bacteria by transformation, conjugation or any other method. Because they lack an autonomously replicating origin of replication, only the bacteria that have recombined the plasmid into their genome will stably maintain the selection marker and survive a selection step. The plasmid being stably integrated and maintained in progeny cells, the progeny cells will also be able to survive in presence of the selection marker.
The most commonly used conditional origin of replication is based on the wild-type plasmid R6K and derivatives which belong to the IncX group of replicon, a group commonly found in a variety of bacterial isolates. The replication of these plasmids is dependent on binding of the pir encoded Π initiator protein to the origin of replication. This protein can be expressed from a different replicon (in trans) than the plasmid carrying the R6K origin of replication. In this situation the replication of the R6K on plasmid is conditional on the expression of the pir gene in trans. When delivered to a bacteria of interest, the plasmid will not replicate unless the pir gene is present and expressed.
Similar conditional origins have also been built based on other systems including ColE1 origins (Panayotatos (1984) Nucleic Acids Res. 12:2641-2648) or IncPalpha oriV (Matsumoto-Mashimo et al. (2004) Res. Microbiol. 155:455-461). There are several drawbacks associated with these systems if one would try to build a system with minimal risk of genetically modified material spread in an in vivo setting (human, environment or animal for instance). Notably, such systems are inspired from origins that are almost ubiquitous in nature, such as ColE1 and R6K-type for instance that can be found in many Enterobacteria. Having such an origin on a recombinant plasmid delivered into a microbiome therefore significantly increases the chances not only of recombination with between the recombinant plasmid and wild-type elements within the microbiome, but also of having such plasmid being replicated within this microbiome since the wild-type elements would bring the missing factor necessary for the replication of the plasmid. Additionally, since inducible systems are usually leaky, conditional origins of replication relying on such system have a high chance of being replicated at a basal level—enough to spread in the population—or even at a full replication level if the inducer is present in the target population (for instance, LacI-based origins will be active if lactose is present, which is very often the case in vivo, given modern age diet).
The aim of the present invention is specifically to engineer and efficiently produce vehicles containing a DNA payload that can be transferred to a target bacterial population, not with the purpose of making and selecting recombination events between the DNA payload and the target bacterial genome to create stably genetically modified bacteria that can transfer the modification to progeny cells, but on the opposite with the purpose of limiting and/or preventing the creation of genetically modified progeny cells while still enabling a direct or indirect effect on the bacteria it is delivered into or its host via the efficient expression of genes of interest carried on the DNA payload.
Desired effects to be obtained in targeted bacteria or the host include therapeutic effect, cosmetic effect, bioremediation effect, effects on plant growth or physiology, effects on animal growth or physiology as non limiting examples.
Achieving therapeutic or other type of effect on a target bacteria or its environment with a non-replicative vector is not an obvious development for the simple reason that it can only be achieved if the DNA payload is efficiently delivered to the target bacteria and if it can be expressed to a high enough level and for a sufficient amount of time despite its non-replicative nature. While a replicative plasmid will produce copies of itself, increasing gene dosage, and will be passed down to daughter cells enabling a significant maintenance time in the bacterial population, none of these effects occur with a non-replicative plasmid.
The present inventors here demonstrate, for the first time, that it is possible to obtain an effect in vivo, such as a therapeutic effect, with the delivery of a non-replicative vector to a bacteria.
To this purpose, the present inventors developed a novel conditional origin of replication particularly efficient for this application, that is based on a rarely occurring two-system components to limit recombination events in the target population, the primase and origin of replication of phage-like inducible elements, namely phage-inducible chromosomal islands (PICIs), and they demonstrate for the first time that such type of conditional origin, even with the primase in trans, enables the efficient packaging of the DNA payload into the delivery vehicle, here a phage-derived particle or packaged phagemid.
PICIs, disclosed in Fillol-Salom et al. (2018) The ISME Journal 12:2114-2128 or in Fillol-Salom et al. (2019) Mol. Cell 75:1020-1030 are systems similar to P4-like elements that hijack Myoviridae, with the main difference that, according to current research, they do not modify the size of the capsid to accommodate their genomes. Since lambdoid PICIs are usually 10-13 kb long and the phages they hijack possess genomes close to 50 kb, this means that they are able to insert several copies of their small genome into a large capsid.
According to research, PICIs are able to completely abolish phage production and only lead to the packaging of their genomes. PICIs sense when the lambdoid phage to be hijacked is being induced, they excise from the genome where they reside as prophage-like islands and they replicate their genomes. Replication is based on a single protein, the primase, containing primase and helicase activity, and a short DNA fragment, usually right after the primase gene, that is recognized as an origin of replication by the primase. Additionally, many different PICIs have been described, each one containing different primase-ori pairs.
Fillol-Salom et al. (2018) The ISME Journal 12:2114-2128 specifically discloses PICIs originating in E. coli strain CFT073. In this document, the authors show that the genetic module containing the primase and the ori can function as an independent replication module when inserted in cis in thermosensitive-origin-containing plasmids: at the permissive temperature, the plasmid replicates through the plasmid origin, but when shifted to the non-permissive temperature, the primase and ori module acts as the main source of replication of the plasmid. However, from this observation it is not clear for the skilled person if, even at the non-permissive temperature, replication may have been due to the thermosensitive origin at some degree as it can happen; if the primase and ori can be physically separated (i.e., putting them apart from each other on the same plasmid or having a system in trans) and still enables the replication of the plasmid; and finally, if the ori, that is located right downstream of the primase, is the only element needed for replication or if there is a second element needed and if a specific orientation of the different elements is important, such as in P4, where two elements, the ori and the crr sequence, moreover in a specific orientation, are needed for replication (Flensberg et al. (1987) J. Mol. Biol. 195:439-445).
While other primase-based systems have been developed in which the primase protein is expressed in trans (Ziegelin et al. (2005) J. Bacteriol. 187:3445-3454), it is not known if this type of replication is compatible with phagemid packaging, and even in the case it could be, it would be even less obvious to predict that the packaging would be efficient.
It is indeed also very important that the DNA payload and its vehicle are produced very efficiently in order to be economically viable, which is not an obvious development either. Indeed, some studies have shown that the production titers of phage-derived particles packaging a DNA payload containing a conditional on were reduced by at least 3 logs compared to a DNA payload containing a non-conditional ori, and despite multiple engineering trials, this titer could not get increased.
The present invention arises from the unexpected finding that not only a DNA payload devoid of antibiotic resistance marker and autonomously replicative origin of replication can be packaged at high-titer in phage-derived particles but also that these DNA payloads can be efficiently delivered to the target bacteria and that these DNA payloads, while non replicative, can exert the intended effect. In particular, the present inventors also demonstrated for the first time that a non replicative DNA payload expressing a nuclease or an engineered nuclease, such as a base-editor, can result in similar killing or base-editing efficiency as its replicative counterpart.
The present invention thus concerns a method for in vivo modulating the microbiome of a host organism by delivering a nucleic acid of interest into a targeted receiver bacterial cell of said microbiome, said nucleic acid of interest producing a given effect on said targeted receiver bacterial cell,
The present invention also concerns a method for in vivo modulating the microbiome of a host organism by delivering a nucleic acid of interest into a targeted receiver bacterial cell of said microbiome, said nucleic acid of interest being expressed in said targeted receiver bacterial cell, thereby producing a given effect on said targeted receiver bacterial cell,
In a particular embodiment, said given effect on said targeted receiver bacterial cell generates, directly or indirectly, a reaction in said organism hosting said targeted receiver bacterial cell.

The present invention relates to methods for in vivo modulating the microbiome of a host organism.
By “microbiome” is meant herein the aggregate of all microbiota that reside on or within an organism tissues and biofluids along with the corresponding anatomical sites in which they reside, including, for mammalian organisms, the skin, mammary glands, placenta, seminal fluid, vagina, uterus, ovarian follicles, lung, saliva, oral mucosa, conjunctiva, biliary tract, and gastrointestinal tract, blood, tumors, brain. In a particular embodiment, the microbiome more specifically refers to the bacteria populations forming said microbiota.
By “modulating the microbiome” is meant herein exerting a modifying or controlling influence on the microbiome. In the context of the invention, modulating the microbiome encompases modulating the microbiome function and/or modulating the microbiome composition.
By “modulating the microbiome composition” is meant herein changing the composition of said microbiome, including removing specific species or strains of said microbiome, changing the proportion between different species or strains of said microbiome or replacing specific species or strains of said microbiome by other species or strains. Said modulation of the microbiome composition can be achieved directly or indirectly, typically by modifying said targeted bacterial cell, which can then have an effect, such as a killing effect, on other bacteria of the microbiome, which were not initially targeted by said vector.
By “modulating the microbiome function” is meant herein changing the function of specific species or strains of said microbiome, for example by making specific species or strains express particular molecules, or by making specific species or strains stop expressing particular molecules.
By “host organism” is meant herein any multicellular organism, including any animal or any plant. In a particular embodiment, said host organism is a host subject.
By “host subject” is meant herein any animal (e.g., a primate, e.g., a human) hosting said microbiome. The subject according to the invention is preferably a mammal, even more preferably a human. However, the term “subject” can also refer to non-human animals, in particular mammals such as dogs, cats, horses, cows, pigs, sheep, donkeys, rabbits, ferrets, gerbils, hamsters, chinchillas, rats, mice, guinea pigs and non-human primates, among others, or non-mammals such as poultry, that are in need of treatment.
The human subject according to the invention may be a human at the prenatal stage, a new-born, a child, an infant, an adolescent or an adult at any age.
In the method of the present invention, a nucleic acid of interest is delivered into a targeted receiver bacterial cell of said microbiome or a group of targeted receiver bacterial cells of said microbiome, said nucleic acid of interest being comprised in a vector provided by a donor bacterial cell.
By “donor bacterial cell” is meant herein a bacterium that is capable of hosting a vector comprising a nucleic acid of interest, of producing a vector comprising said nucleic acid of interest and/or which is capable of transferring said vector comprising said nucleic acid to another bacterium. In a particular embodiment, said vector may be a phagemid, and said donor bacterial cell may then be a bacterial cell able to produce said phagemid, more particularly in the form of a packaged phagemid. In an alternative embodiment, said vector may be a plasmid, more particularly a conjugative plasmid, and said donor bacterial cell may then be a bacterium that is capable of transferring said conjugative plasmid to another bacterium, in particular by conjugation.
By “receiver bacterial cell’ is meant herein any bacterium from the host microbiome which is specifically targeted to be delivered with said nucleic acid of interest.
The targeted receiver bacteria can be any bacteria, in particular present in an organism, more particularly in a mammal organism. It can be any commensal, symbiotic or pathogenic bacteria of the microbiota or microbiome.
A microbiome may comprise a variety of endogenous bacterial species, any of which may be targeted in accordance with the present disclosure. In some embodiments, the genus and/or species of targeted receiver bacterial cells may depend on the type of bacteriophages being used for preparing the vector and/or bacterial delivery vehicles. For example, some bacteriophages exhibit tropism for, or preferentially target, specific host species of bacteria. Other bacteriophages do not exhibit such tropism and may be used to target a number of different genus and/or species of endogenous bacterial cells.

Cytosine base editors (CBE) and Adenosine base editors (ABE), as described in Rees et al. (2018) Nat Rev Genet 19:770-788, which is hereby incorporated by reference.
So far there are seven types of DNA base editors described:
Base editors differ in the base modification enzymes. CBE rely on ssDNA cytidine deaminase among which: APOBEC1, rAPOBEC1, APOBEC1 mutant or evolved version (evoAPOBEC1), and APOBEC homologs (APOBEC3A (eA3A), Anc689), Cytidine deaminase 1 (CDA1), evoCDA1, FERNY, evoFERNY.
ABE rely on deoxyadenosine deaminase activity of a tandem fusion TadA-TadA* where TadA* is an evolved version of TadA, an E. coli tRNA adenosine deaminase enzyme, able to convert adenosine into Inosine on ssDNA.TadA* include TadA-8a-e and TadA-7.10.
Except from base modification enzyme there has been also modifications implemented to base editor to increase editing efficacy, precision and modularity:
Non-limiting examples of DNA based editor proteins include BE1, BE2, BE3, BE4, BE4-GAM, HF-BE3, Sniper-BE3, Target-AID, Target-AID-NG, ABE, EE-BE3, YE1-BE3, YE2-BE3, YEE-BE3, BE-PLUS, SaBE3, SaBE4, SaBE4-GAM, Sa(KKH)-BE3, VQR-BE3, VRER-BE3, EQR-BE3, xBE3, Cas12a-BE, Ea3A-BE3, A3A-BE3, TAM, CRISPR-X, ABE7.9, ABE7.10, ABE7.10*, xABE, ABESa, VQR-ABE, VRER-ABE, Sa(KKH)-ABE, ABE8e, SpRY-ABE, SpRY-CBE, SpG-CBE4, SpG-ABE, SpRY-CBE4, SpCas9-NG-ABE, SpCas9-NG-CBE4, enAsBE1.1, enAsBE1.2, enAsBE1.3, enAsBE1.4, AsBE1.1, AsBE1.4, CRISPR-Abest, CRISPR-Cbest, eA3A-BE3, AncBE4.
Cytosine Guanine Base Editors (CGBE) consist of a nickase CRISPR fused to:
Cytosine Adenine Base Editors (CABE) consist of a Cas9 nickase, a cytidine deaminase (e.g. AID), and a uracil-DNA glycosylase (Ung) (Zhao et al. (2020) Nature Biotechnol. “New base editors change C to A in bacteria and C to G in mammalian cells”).
ACBE include a nucleic acid programmable DNA-binding protein and an adenine oxidase (WO2020181180).
ATBE consist of a Cas9 nickase and one or more adenosine deaminase or an oxidase domain (WO2020181202).
TABE consist of a Cas9 nickase and an adenosine methyltransferase, a thymine alkyltransferase, or an adenosine deaminase domain (WO2020181193, WO2020181178, WO2020181195).
Base editor molecules can also consist of two or more of the above listed editor enzymes fused to a Cas protein (e.g. combination of an ABE and CBE). These biomolecules are named dual base editors and enable the editing of two different bases (Grunewald et al. (2020) Nature Biotechnol. “A dual-deaminase CRISPR base editor enables concurrent adenine and cytosine editing”; Li et al. (2020) Nature Biotechnol. “Targeted, random mutagenesis of plant genes with dual cytosine and adenine base editors”).
Prime editors (PE), as described in Anzalone et al. (2019) Nature 576:149-157, which is hereby incorporated by reference, consist of nCas9 fused to a reverse transcriptase used in combination with a prime editing RNA (pegRNA, a guide RNA that includes a template region for reverse transcription).
Prime Editing allows introduction of insertions, deletions (indels) and 12 base-to-base conversions. Prime editing relies on the ability of a reverse transcriptase (RT), fused to a Cas nickase variant, to convert RNA sequence brought by a prime editing guide RNA (pegRNA) into DNA at the nick site generated by the Cas protein. The DNA flap generated from this process is then included or not in the targeted DNA sequence.
Prime editing systems include:
To favor editing the prime editing system can include the expression of an additional sgRNA targeting the Cas nickase activity towards the non-edited DNA strand ideally only after the resolution of the edited strand flap by designing the sgRNA to anneal with the edited strand but not with the original strand.
Non-limiting examples of prime editing systems include PE1, PE1-M1, PE1-M2, PE1-M3, PE1-M6, PE1-M15, PE1-M3inv, PE2, PE3, PE3b.
Cas9 Retron precISe Parallel Editing via homologY (‘CRISPEY’), a retron RNA fused to the sgRNA and expressed together with Cas9 and the retron proteins including at least the reverse transcriptase (Sharon et al. (2018) Cell 175:544-557.e16).
The SCRIBE strategy: a retron system expressed in combination with a recombinase promoting the recombination of single stranded DNA, also known as single stranded annealing proteins (SSAPs) (Farzadfard & Lu (2014) Science 346:1256272). Such recombinases include but are not limited to phage recombinases such as lambda red, recET, Sak, Sak4, and newly described SSAPs described in Wannier et al. (2020) Proc Natl Acad Sci USA 117(24):13689-13698 which is hereby incorporated by reference.
The targetron system based on group II introns described in Karberg et al. (2001) Nat Biotechnol 19:1162-7, which is hereby incorporated by reference, and which has been adapted to many bacterial species.
Other retron based gene targeting approaches are described in Simon et al. (2019) Nucleic Acids Res 47:11007-11019, which is hereby incorporated by reference.
In a particular embodiment, the CRISPR system is included in the nucleic acid of interest. The CRISPR system contains two distinct elements, i.e. i) an endonuclease, in this case the CRISPR associated nuclease (Cas or “CRISPR associated protein”) and ii) a guide RNA. The guide RNA may be in the form of a chimeric RNA which consists of the combination of a CRISPR (RNAcr) bacterial RNA and a RNAtracr (trans-activating RNA CRISPR) (Jinek et al. (2012) Science 337(6096):816-21). The guide RNA combines the targeting specificity of the RNAcr corresponding to the “spacing sequences” that serve as guides to the Cas proteins, and the conformational properties of the RNAtracr in a single transcript. When the guide RNA and the Cas protein are expressed simultaneously in the cell, the target genomic sequence can be permanently modified or interrupted. The modification is advantageously guided by a repair matrix. In general, the CRISPR system includes two main classes depending on the nuclease mechanism of action. Class 1 is made of multi-subunit effector complexes and includes type I, III and IV. Class 2 is made of single-unit effector modules, like Cas9 nuclease, and includes type II (II-A,II-B,II-C,II-C variant), V (V-A,V-B,V-C,V-D,V-E,V-U1,V-U2,V-U3,V-U4,V-U5) and VI (VI-A,VI-B1,VI-B2,VI-C,VI-D)
The nucleic acid of interest according to the present disclosure may comprise a nucleic acid sequence encoding Cas protein. A variety of CRISPR enzymes are available for use as a sequence of interest on the plasmid. In some embodiments, the CRISPR enzyme is a Type II CRISPR enzyme. In some embodiments, the CRISPR enzyme catalyzes DNA cleavage. In some other embodiments, the CRISPR enzyme catalyzes RNA cleavage. Preferably, the CRISPR enzyme does not make a double strand break. In some embodiments, the CRISPR enzyme makes a single strand break or nicks. In some embodiments, the CRISPR enzyme does not make any break in the DNA or RNA. In one embodiment, a Cas13-deaminase fusion is used to base edit an RNA.
In one embodiment, the CRISPR enzymes may be coupled to a sgRNA. In certain embodiments, the sgRNA targets a gene encoding a given molecule as defined above.
Non-limiting examples of Cas proteins as part of a multi-subunit effector or as a single-unit effector include Cas1, Cas1B, Cas2, Cas3, Cas4, Cas5, Cas6, Cas7, Cas8, Cas9 (also known as Csn1 and Csx12), Cas10, Cas11 (SS), Cas12a (Cpf1), Cas12b (C2c1), Cas12c (C2c3), Cas12d (CasY), Cas12e (CasX), C2c4, C2c8, C2c5, C2c10, C2c9, Cas13a (C2c2), Cas13b (C2c6), Cas13c (C2c7), Cas13d, Csa5, Csc1, Csc2, Cse1, Cse2, Csy1, Csy2, Csy3, Csf1, Csf2, Csf3, Csf4, Csm2, Csm3, Csm4, Csm5, Csm6, Cmr1, Cmr3, Cmr4, Cmr5, Cmr6, Csn2, Csb1, Csb2, Csb3, Csx17, Csx14, Csx10, Csx16, CsaX, Csx13, Csx1, Csx15, SdCpf1, CmtCpf1, TsCpf1, CmaCpf1, PcCpf1, ErCpf1, FbCpf1, UbcCpf1, AsCpf1, LbCpf1, Mad4, Mad7, Cms1, homologues thereof, orthologues thereof, variants thereof, or modified versions thereof. In some embodiments, the CRISPR enzyme cleaves both strands of the target nucleic acid at the Protospacer Adjacent Motif (PAM) site.
In various embodiments, the invention encompasses fusion proteins comprising a Cas9 (e.g., a Cas9 nickase) domain and a deaminase domain. In some embodiments, the fusion protein comprises Cas9 and a cytosine deaminase enzyme, such as APOBEC enzymes, or adenosine deaminase enzymes, such as ADAT enzymes, for example as disclosed in U.S. Patent Publ. 2015/0166980, which is hereby incorporated by reference. In one embodiment, the deaminase is an ACF1/ASE deaminase.
In various embodiments, the APOBEC deaminase is selected from the group consisting of APOBEC1 deaminase, APOBEC2 deaminase, APOBEC3A deaminase, APOBEC3B deaminase, APOBEC3C deaminase, APOBEC3D deaminase, APOBEC3F deaminase, APOBEC3G deaminase, and APOBEC3H deaminase. In various embodiments, the fusion protein comprises a Cas9 domain, a cytosine deaminase domain, and a uracil glycosylase inhibitor (UGI) domain.
In one embodiment, the deaminase is an adenosine deaminase that deaminate adenosine in DNA, for example as disclosed in U.S. Pat. No. 10,113,163, which is hereby incorporated by reference. In some embodiments, the fusion proteins further comprise an inhibitor of base repair, such as, a nuclease dead inosine specific nuclease (dISN), for example as disclosed in U.S. Pat. No. 10,113,163. In various embodiments, the invention encompasses fusion proteins comprising a catalytically impaired Cas9 endonuclease fused to an engineered reverse transcriptase, programmed with a prime editing guide RNA (pegRNA) that both specifies the target site and encodes the desired edit, for example as described in Anzalone et al.

In a particular embodiment, the CRISPR enzyme is any Cas protein, in particular any Cas9 protein, for instance any naturally occurring bacterial Cas9 as well as any variants, chimeras, homologs or orthologs thereof.
By “Cas9” is meant a protein Cas9 (also called Csn1 or Csx12) or a functional protein, peptide or polypeptide fragment thereof, i.e. capable of interacting with the guide RNA(s) and of exerting the enzymatic activity (nuclease) which allows it to perform the double-strand cleavage of the DNA of the target genome. “Cas9” can thus denote a modified protein, for example truncated to remove domains of the protein that are not essential for the predefined functions of the protein, in particular the domains that are not necessary for interaction with the gRNA(s).
The sequence encoding Cas9 (the entire protein or a fragment thereof) as used in the context of the disclosure can be obtained from any known Cas9 protein (Fonfara et al. (2014) Nucleic Acids Res 42(4):2577-90; Shmakov et al. (2017) Nat Rev Microbiol 15(3):169-182). Examples of Cas9 proteins useful in the present disclosure include, but are not limited to, Cas9 proteins of Streptococcus pyogenes (SpCas9), Streptococcus thermophiles (St1Cas9, St3Cas9), Streptococcus mutans, Staphylococcus aureus (SpCas9), Campylobacter jejuni (CjCas9), Francisella novicida (FnCas9) and Neisseria meningitides (NmCas9).
The sequence encoding Cpf1 (Cas12a) (the entire protein or a fragment thereof) as used in the context of the disclosure can be obtained from any known Cpf1 (Cas12a) protein (Koonin et al. (2017) Current Opinion in Microbiology 37:67-78). Examples of Cpf1(Cas12a) proteins useful in the present disclosure include, but are not limited to, Cpf1(Cas12a) proteins of Acidaminococcus sp, Lachnospiraceae bacteriu and Francisella novicida.
The sequence encoding Cas13a (the entire protein or a fragment thereof) can be obtained from any known Cas13a (C2c2) protein (Abudayyeh et al. (2017) Nature 550:280). Examples of Cas13a (C2c2) proteins useful in the present disclosure include, but are not limited to, Cas13a (C2c2) proteins of Leptotrichia wadei (LwaCas13a).
The sequence encoding Cas13d (the entire protein or a fragment thereof) can be obtained from any known Cas13d protein (Yan et al. (2018) Mol Cell 70(2):327-339). Examples of Cas13d proteins useful in the present disclosure include, but are not limited to, Cas13d proteins of Eubacterium siraeum and Ruminococcus sp.
The sequence encoding Mad4 (the entire protein or a fragment thereof) as used in the context of the invention is disclosed in international application WO2018/236548.
The sequence encoding Mad7 (the entire protein or a fragment thereof) as used in the context of the invention is disclosed in international application WO2018/236548.
The sequence encoding Cms1 (the entire protein or a fragment thereof) as used in the context of the invention is disclosed in international patent application WO2017/141173.
In some embodiments, other programmable nucleases can be used. These include an engineered TALEN (Transcription Activator-Like Effector Nuclease) and variants, engineered zinc finger nuclease (ZFN) variants, natural, evolved or engineered meganuclease or recombinase variants, and any combination or hybrids of programmable nucleases. Thus, the programmable nucleases provided herein may be used to selectively modify DNA encoding a gene of interest such as, for example, a toxin gene, a virulence factor gene, an antibiotic resistance gene, a remodeling gene or a modulatory gene (cf. WO2014124226 and US2015/0064138).
In some embodiments, the genetic modification is made at the RNA level. RNA base editing is based on the same principle as DNA base editing: an enzyme catalyzing the conversion of a RNA base into another must be brought close to the target base to perform its conversion locally. In one embodiment, the enzyme used for RNA editing is an adenosine deaminase from ADAR family that converts Adenosine into Inosine in dsRNA structure. Several seminal studies used this specificity for dsRNA and fused the ADAR deaminase domain (ADARDD) to an antisense oligo in order to program local RNA base editing. More recently the ability of some CRISPR-Cas systems to bind RNA molecules was repurposed into RNA editing. Using catalytically dead Cas13b enzyme (dPspCas13b) fused to a hyperactive mutant of ADAR2 deaminase domain (ADAR2DD-E488Q for REPAIRv1 and ADAR2DD-E488Q-T375G for REPAIRv2) Cox et al improved specificity and efficiency compare to previous RNA editing strategies. Non-limiting examples of RNA based editor proteins include REPAIRv1, REPAIRv2
In a particular embodiment, the modification is made in a gene selected in the group consisting of an antibiotic resistance gene, virulence factor or protein gene, toxin factor or protein gene, a gene expressing a bacterial receptor, a membrane protein, a structural protein, a secreted protein, and a gene expressing resistance to a drug in general.
In one embodiment, the modification is made to target and inactivate a virulence factor. A virulence factor can be any substance produced by a pathogen that alters host-pathogen interaction by increasing the degree of damage done to the host. Virulence factors are used by pathogens in many ways, including, for example, in cell adhesion or colonization of a niche in the host, to evade the host's immune response, to facilitate entry to and egress from host cells, to obtain nutrition from the host, or to inhibit other physiological processes in the host. Virulence factors can include enzymes, endotoxins, adhesion factors, motility factors, factors involved in complement evasion, and factors that promote biofilm formation. For example, such targeted virulence factor gene can be E. coli virulence factor gene such as, without limitation, EHEC-HlyA, Stx1 (VT1), Stx2 (VT2), Stx2a (VT2a), Stx2b (VT2b), Stx2c (VT2c), Stx2d (VT2d), Stx2e (VT2e) and Stx2f (VT2f), Stx2h (VT2h), fimA, fimF, fimH, neuC, kpsE, sfa, foc, iroN, aer, iha, papC, papGI, papGII, papGIII, hlyC, cnf1, hra, sat, ireA, usp ompT, ibeA, malX, fyuA, irp2, traT, afaD, ipaH, eltB, estA, bfpA, eaeA, espA, aaiC, aatA, TEM, CTX, SHV, csgA, csgB, csgC, csgD, csgE, csgF, csgG, csgH, T1SS, T2SS, T3SS, T4SS, T5SS, T6SS (secretion systems).

For example, such targeted virulence factor gene can be Vibrio cholera virulence factor gene such as, without limitation, ctxA and ctxB (cholera toxin), tcpA (toxin co-regulated pilus), and toxT (master virulence regulator). For example, such targeted virulence factor gene can be Pseudomonas aeruginosa virulence factor genes such as, without limitation, pyoverdine (e.g., sigma factor pvdS, biosynthetic genes pvdL, pvdI, pvdJ, pvdH, pvdA, pvdF, pvdQ, pvdN, pvdM, pvdO, pvdP, transporter genes pvdE, pvdR, pvdT, opmQ), siderophore pyochelin (e.g., pchD, pchC, pchB, pchA, pchE, pchF and pchG, and toxins (e.g., exoU, exoS and exoT).

For example, such targeted virulence factor gene can be Salmonella enterica Typhi virulence factor genes such as, without limitation, MIA (invasion, SPI-1 regulator), ssrB (SPI-2 regulator), and those associated with bile tolerance, including efflux pump genes acrA, acrB and tolC. For example, such targeted virulence factor gene can be Fusobacterium nucleatum virulence factor genes such as, without limitation, FadA and TIGIT.

In another embodiment, the modification is made in a bacterial toxin gene. Bacterial toxins can be classified as either exotoxins or endotoxins. Exotoxins are generated and actively secreted; endotoxins remain part of the bacteria. The response to a bacterial toxin can involve severe inflammation and can lead to sepsis.

In a particular embodiment, said toxin is Shiga toxin.
In some embodiments, the modification is made in a mimic peptide gene sequence so that the homology with the human peptide sequence is reduced, and therefore results in the mimic peptide being not recognized anymore by the host immune system. Mimic peptides of particular interest are bacterial mimic peptides that are associated with auto-immune diseases, for example those mentioned in Negi et al. (2017) Plos One 12:e0180518, which are hereby incorporated by reference. Of particular interest are the gene sequences encoding any of the mimic peptides in S1 Table of Negi et al.
In preferred embodiments, the mimic peptide is from Proteobacteria or Firmicutes. Of particular interest are the gene sequences encoding 24 gut bacterial peptides identified by Negi et al. with homology to four human peptides from Low molecular weight phosphotyrosine protein phosphatase, Aldehyde dehydrogenase family 3 member B1, Maleylacetoacetate isomerase and Uracil-DNA glycosylase. These gene sequences can be modified to reduce the homology with the human sequences and prevent cross-reactivity of those recognized by the host immune system with the human counterpart.
In a preferred embodiment, the genetic modification is in the Bacteroides faecis or Bacteroides thetaiotaomicron beta-galactosidase gene. Preferably, the Bacteroides faecis or Bacteroides thetaiotaomicron beta-galactosidase protein with the genetic modification shows lower homology with human MYH6 cardiac peptide as compared to the Bacteroides faecis or Bacteroides thetaiotaomicron beta-galactosidase protein without the genetic modification. Preferably the genetic modification is performed in the peptides fragment recognized as epitope by the human immune system leading to a weaker or absence of epitope recognition by the human immune system.
In a preferred embodiment, the genetic modification is in human commensal bacteria encoding a Ro60 ortholog gene. Preferably, the Ro60 protein resulting from the genetic modification shows lower homology with human Ro60 peptide as compared to the original protein.

Preferably the human bacterial commensal targeted for genetic modification are: Propionibacterium propionicum, Corynebacterium amycolatum, Actinomyces massiliensis, Bacteroides thetaiotaomicron. Even more preferably the human bacterial commensal targeted for genetic modification is Propionibacterium propionicum.
In a preferred embodiment, the genetic modification is in human commensal bacterial DNA sequence encoding a peptide that mimic insulin B 9-25, a self-epitope involved in type 1 diabetes. The genetic mutation reduces homology to the insulin B9-25 epitope SHLVEALYLVCGERGFF (SEQ ID NO: 1). In a preferred embodiment, the target bacteria belong to the Firmicutes phylum. In a preferred embodiment, the target gene in the target bacteria is part of the transketolase N superfamily.
In a preferred embodiment, the genetic modification is in Roseburia intestinalis encoding a peptide that mimic the epitope of the autoantigen β2-glycoprotein I (β2GPI), a self-epitope involved in antiphospholipid syndrome (APS). The genetic mutation is reducing homology to the T cell (β2GP1) epitope KVSFFCKNKEKKCSY (SEQ ID NO: 2) and/or B cell epitope VSRGGMRKFIC (SEQ ID NO: 3).
The genetic modification can be in the translated or untranslated regions of a gene. The genetic modification can be in the promoter region of a gene or within any other region involved in gene regulation. In some embodiments, the genetic modification results in the change in at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 20, 25, 30, 35, 40, 45, 50, 100, 200, 500, etc. amino acids to a different amino acid. In some embodiments, the genetic modification introduces a stop codon. In some embodiments, the genetic modification is outside protein coding sequences, within RNA, or within regulatory sequences.
Preferably, the genetic modification does not integrate a phage genome or exogenous DNA into the host bacterial chromosome or endogenous plasmid(s). Preferably, the genetic modification does not result in expression of an exogenous protein from an integrated exogenous DNA in the host bacterial chromosome or endogenous plasmid(s). Most preferably, the genetic modification does not involve either NHEJ or HR endogenous repair mechanism of the host bacteria.
Killing the Receiver Bacterial Cell
In a particular embodiment, said given effect is killing the receiver bacterial cell.
In a particular embodiment, said nucleic acid of interest is a gene encoding a nuclease.
In one embodiment, the nucleic acid of interest is a programmable nuclease circuit to be delivered to the targeted bacteria. This programmable nuclease circuit may be able to mediate in vivo sequence-specific elimination of bacteria that contain a target gene of interest (e.g. a gene that is harmful to humans). Some embodiments of the present disclosure relate to engineered variants of different CRISPR-Cas systems classes and types, such as the Type II CRISPR-Cas (Clustered Regularly Interspaced Short Palindromic Repeats-CRISPR-associated) system of Streptococcus pyogenes, as disclosed above. Other programmable nucleases that can be used include other CRISPR-Cas systems, engineered TALEN (Transcription Activator-Like Effector Nuclease) variants, engineered zinc finger nuclease (ZFN) variants, natural, evolved or engineered meganuclease or recombinase variants, and any combination or hybrids of programmable nucleases, as disclosed above. Thus, the programmable nuclease circuit provided herein may be used to selectively cleave DNA encoding a gene of interest such as, for example, a toxin gene, a virulence factor gene, an antibiotic resistance gene, a remodeling gene or a modulatory gene (cf. WO2014124226 and US2015/0064138).
In a particular embodiment, said nuclease is the Cpf1 nuclease.
In a particular embodiment, said nuclease is the Cas9 nuclease
In a particular embodiment, said nuclease is the Mad4 nuclease, as defined above.
In a particular embodiment, said nuclease is the Mad7 nuclease, as defined above.
In a particular embodiment, said nuclease is the Cms1 nuclease, as defined above.
In a particular embodiment, antibiotic resistant strains are targetly killed by programming the nuclease to perform a DNA cleavage, e.g. a double strand DNA break in an antibiotic resistance gene located on the chromosome of the target bacteria or on a plasmid with addictive systems (toxin/antitoxin).
Other sequences of interest, preferably programmable, can be delivered to targeted bacteria to kill it. For example, the nucleic acid of interest may encode holins or toxins.
In a particular embodiment, said nucleic acid of interest further makes the receiver bacterial cell produce a molecule of interest, as disclosed above, in particular a host modulatory molecule, as disclosed above, before being killed or just after being killed as a bacterial host for instance.
In the context of the invention, the nucleic acid of interest may be under the control of a promoter.
As known by the person skilled in the art, a promoter may be classified as strong or weak according to its affinity for RNA polymerase. The strength of a promoter may depend on whether initiation of transcription occurs at that promoter with high or low frequency. Different promoters with different strengths may be used in the present invention leading to different levels of gene/protein expression (e.g. the level of expression initiated from an mRNA originating from a weak promoter is lower than the level of expression initiated from a strong promoter).
It will be appreciated by those of ordinary skill in the art that a promoter sequence may be selected from a large number of known bacterial genes expressed by various bacterial species. Also, methods of prokaryotic promoter prediction exist, and can be based on DNA stability analysis as described in Kanhere and Bansal (BMC Bioinformatics 2005, 6:1). The choice of promoter on the vector according to the present invention can thus be made based on the bacteria to target.
In some embodiments, the nucleic acid of interest may be positioned under the control of a recombinant or heterologous promoter, which refers to a promoter that is not normally associated with the nucleic acid of interest in its natural environment.
Examples of bacterial promoters for use in accordance with the present invention include, without limitation, positively regulated E. coli promoters such as positively regulated a 70 promoters (e.g., inducible pBad/araC promoter, Lux cassette right promoter, modified lambda Prm promote, plac Or2-62 (positive), pBad/AraC with extra REN sites, pBad, P(Las) TetO, P(Las) CIO, P(Rhl), Pu, FecA, pRE, cadC, hns, pLas, pLux), a “s” promoter (e.g., Pdps), σ 32 promoters (e.g., heat shock) and σ 54 promoters (e.g., glnAp2); negatively regulated E. coli promoters such as negatively regulated σ 70 promoters (e.g., Promoter (PRM+), modified lambda Prm promoter, TetR-TetR-4C P(Las) TetO, P(Las) CIO, P(Lac) IQ, RecA_DlexO_DLac01, dapAp, FecA, Pspac-hy, pel, plux-cl, plux-lac, CinR, CinL, glucose controlled, modified Pr, modified Prm+, FecA, Pcya, rec A (SOS), Rec A (SOS), EmrR_regulated, BetI_regulated, pLac_lux, pTet_Lac, pLac/Mnt, pTet/Mnt, LsrA/cl, pLux/cl, LacI, LacIQ, pLacIQI, pLas/cl, pLas/Lux, pLux/Las, pRecA with LexA binding site, reverse BBa_R0011, pLacI/ara-1, pLacIq, rrnB PI, cadC, hns, PfhuA, pBad/araC, nhaA, OmpF, RcnR), σ S promoters (e.g., Lutz-Bujard LacO with alternative sigma factor σ 38), σ 32 promoters (e.g., Lutz-Bujard LacO with alternative sigma factor σ 32), a 54 promoters (e.g., glnAp2); negatively regulated B. subtilis promoters such as repressible B. subtilis σ A promoters (e.g., Gram-positive IPTG-inducible, Xyl, hyper-spank), a promoters, and the BioFAB promoters disclosed in Mutalik V K et al (Nature Methods, 2013, 10: 354-360, see in particular the supplementary data) as well as on the BioFAB website (http://biofab.synberc.org/data). Other inducible microbial promoters and/or bacterial promoters may be used in accordance with the present invention. An inducible promoter for use in accordance with the present disclosure may be induced by (or repressed by) one or more physiological condition(s), such as changes in pH, temperature, radiation, osmotic pressure, saline gradients, cell surface binding, and the concentration of one or more extrinsic or intrinsic inducing agent(s). The extrinsic inducer or inducing agent may comprise, without limitation, amino acids and amino acid analogs, saccharides and polysaccharides, nucleic acids, protein transcriptional activators and repressors, cytokines, toxins, petroleum-based compounds, metal containing compounds, salts, ions, enzyme substrate analogs, hormones or combinations thereof.
Particularly preferred bacterial promoters for use in accordance with the present invention may be selected from constitutive promoters regulated by α70 such as the promoters of the Anderson collection (http://parts.igem.org/Promoters/Catalog/Anderson): BBa_J23100, BBa_J23101, BBa_J23102, BBa_J23103, BBa_J23104, BBa_J23105, BBa_J23106, BBa_J23107, BBa_J23108, BBa_J23109, BBa_J23110, BBa_J23111, BBa_J23112, BBa_J23113, BBa_J23114, BBa_J23115, BBa_J23116, BBa_J23117, BBa_J23118, and BBa_J23119.
Other preferred bacterial promoters are the promoters disclosed in Stanton et al. (2014) Nat. Chem. Biol. 10:99-105, incorporated herein by reference, including in particular TetR, IcaR(A), AmtR, BetI, SrpR, Orf2, BM3R1, ButR, PhlF, PsrA, HlyIIR, AmeR, LmrA, QacR, ScbR, McbR, LitR, HapR, SmcR, TarA and variants thereof. In a particular embodiment, said promoter is SrpR and/or PhlF, or a variant thereof.
In some embodiments of the present invention, a promoter may or may not be used in conjunction with an “enhancer,” which refers to a ds-acting regulatory sequence involved in the transcriptional activation of a nucleic acid sequence downstream of the promoter. The enhancer may be located at any functional location before or after the promoter.
In some embodiments, the vector may comprise a terminator sequence, or terminator. A “terminator,” as used herein, is a nucleic acid sequence that causes transcription to stop. A terminator may be unidirectional or bidirectional. It is comprised of a DNA sequence involved in specific termination of an RNA transcript by an RNA polymerase. A terminator sequence prevents transcriptional activation of downstream nucleic acid sequences by upstream promoters. Thus, in certain embodiments, a terminator that ends the production of an RNA transcript is contemplated. A terminator may be necessary in vivo to achieve desirable gene/protein expression levels.
The most commonly used type of terminator is a forward terminator. When placed downstream of a nucleic acid of interest that is usually transcribed, a forward transcriptional terminator will cause transcription to abort. In some embodiments, bidirectional transcriptional terminators are provided, which usually cause transcription to terminate on both the forward and reverse strand. In some embodiments, reverse transcriptional terminators are provided, which usually terminate transcription on the reverse strand only. In prokaryotic systems, terminators usually fall into two categories (1) rho-independent terminators and (2) rho-dependent terminators. Rho-independent terminators are generally composed of palindromic sequence that forms a stem loop rich in G-C base pairs followed by a string of uracil bases.
Terminators for use in accordance with the present invention include any terminator of transcription described herein or known to one of ordinary skill in the art. Examples of terminators include, without limitation, the termination sequences of genes such as, for example, the bovine growth hormone terminator, and viral termination sequences such as, for example, the TO terminator, the TE terminator, lambda TI and the T1T2 terminator found in bacterial systems. In some embodiments, the termination signal may be a sequence that cannot be transcribed or translated, such as those resulting from a sequence truncation.
Terminators for use in accordance with the present invention also include terminators disclosed in Chen Y J et al (2013, Nature Methods, 10: 659-664), and the BioFAB terminators disclosed in Cambray G et al (Nucl Acids Res, 2013, 41(9): 5139-5148).
As used herein, the term “vector” refers to a nucleic acid molecule, typically DNA or RNA that serves to transfer a passenger nucleic acid sequence, i.e. DNA or RNA, into a receiver or target cell. A vector may comprise an origin of replication, a selectable marker, and optionally a suitable site for the insertion of a gene such as the multiple cloning site. There are several common types of vectors including plasmids, bacteriophage genomes, phagemids, phage-plasmids, virus genomes, cosmids, and artificial chromosomes.
In the context of the invention, a vector may be referred to as a payload.
The vector used in the context of the invention may be a plasmid (e.g, a conjugative plasmid capable of transfer into a host cell), phage, phagemid or prophage.
The payload can be a phagemid or phasmid obtained from natural, evolved or engineered bacteriophage genome. The payload can also be composed only in part of phagemid or phasmid obtained from natural, evolved or engineered bacteriophage genome.
In some embodiments, the payload is the delivery vehicle as bacteria are naturally competent to take up a payload from the environment on their own.
As used herein, the terms “phagemid” and “phasmid” are equivalent and refer to a vector that derives from both a plasmid and a bacteriophage genome. A phagemid of the disclosure comprises a phage packaging site and an origin of replication (ori), as disclosed below.
As used herein, the term “packaged phagemid” refers to a phagemid which is encapsidated in a bacteriophage scaffold, bacterial virus particle or capsid. Particularly, it refers to a bacteriophage scaffold, bacterial virus particle or capsid devoid of a bacteriophage genome. The packaged phagemid may be produced with a helper phage strategy, well known from the man skilled in the art. The helper phage comprises all the genes coding for the structural and functional proteins that are indispensable for the phagemid according to the invention to be encapsidated. The packaged phagemid may be produced with a satellite virus strategy, also known from the man skilled in the art. Satellite virus are subviral agent and are composed of nucleic acid that depends on the co-infection of a host cell with a helper virus for all the morphogenetic functions, whereas for all its episomal functions (integration and immunity, multicopy plasmid replication) the satellite is completely autonomous from the helper. In one embodiment, the satellite genes can encode proteins that promote capsid size reduction of the helper phage, as described for the P4 Sid protein that controls the P2 capsid size to fit its smaller genome.
In a particular embodiment, when said vector is a packaged phagemid, said vector does not comprise any element derived from the organism from which the conditional origin of replication is derived. In particular, the packaging site of said vector is not derived from the organism from which the conditional origin of replication is derived.
Vectors can include, without limitation, plasmid vectors and recombinant phage vectors. The skilled artisan is well aware of the genetic elements that must be present on the vector in order to successfully transform and select host cells comprising any of the isolated nucleotides or nucleic acid sequences of the invention.
As used herein, the term “conjugative plasmid” refers to a plasmid that is transferred from one bacterial cell to another during conjugation and a “donor bacterium”, as used herein, is then a bacterium that is capable of transferring a conjugative plasmid to another bacterium.
The vector used in the context of the invention is devoid of antibiotic resistance marker.
Antibiotic resistance genes are well known in the art and include but are not limited to ampicillin resistance (Amp), chloramphenicol resistance (Cm), tetracycline resistance (Tet), kanamycin resistance (Kan), hygromycin resistance (Qiyg or hph genes), and zeomycin resistance (Zeo).
In a particular embodiment, the vector used in the context of the invention comprises an auxotrophic marker. Auxotrophic markers in bacteria have previously been described, for example, in U.S. Pat. Nos. 4,920,048, 5,691,185, 6,291,245, 6,413,768, and 6,752,994; U.S. Patent Publication No. 20050186666; Struhl et al. (1976) PNAS USA 73; 1471-1475; MacCormick et al., (1995) FEMS Microbiol. Lett. 127:105-109; Dickely et al. (1995) Mol. Microbiol. 15:839-847; Sorensen et al. (2000) Appl. Environ. Microbiol 66:1253-1258; and Fiedler & Skerra (2001) Gene 274: 111 118, all incorporated herein by reference, and typically include DapA and ThyA. In a particular embodiment, said auxotrophic marker is ThyA.
In a particular embodiment, said vector does not comprise any restriction site recognized by restriction enzymes which are frequently encoded by said targeted receiver bacterial cell. In another particular embodiment, said vector comprises no more than 40, 30, 20, 10, 9, 8, 7, 6, 5, 4, 3, 2 or 1 restriction site(s) recognized by restriction enzymes which are frequently encoded by said targeted bacterial cell or a population or a group of targeted bacterial cell(s).
As used herein, the terms “restriction site” and “restriction enzyme site” are equivalent and refer to locations on a nucleic acid containing specific sequences of nucleotides, which are recognized by restriction enzymes. In particular, the nucleic acid comprises specific sequences which are bound and cleaved by restriction enzymes. Restriction sites are generally palindromic sequences of 4-8 base pairs in length. More precisely, the restriction site refers to a particular sequence and a modification state, so as to be bound and cleaved by restriction enzymes. In particular, it refers to a particular unmodified sequence, so as to be bound and cleaved by restriction enzymes. Especially the sequence is not methylated, hydroxymethylated and glucosyl-hydroxymethylated. In this context, the restriction enzyme is of type I, II or III. Alternatively, it may refer to a particular modified sequence, so as to be bound and cleaved by restriction enzymes, for instance a methylated, hydroxymethylated and glucosyl-hydroxymethylated DNA. In this context, the restriction enzyme is of type IV.
As used herein, “recognized by” with respect to a restriction site and a restriction enzyme means that the restriction site is cleaved by the restriction enzyme.
In a restriction site sequence N means that the nucleotide can be A, C, G or T; B means that the nucleotide can be C, G or T; Y means that the nucleotide can be C or T; W means that the nucleotide can be A or T; R means that the nucleotide can be A or G; and D means A, G or T.
As used herein, the terms “restriction enzyme” and “restriction endonuclease” are equivalent and refer to an enzyme that cuts nucleic acids at or near restriction sites. Restriction enzymes are commonly classified into four types (types I to type IV). The REBASE database allow to list the restriction sites that a given bacterium can recognize according to the restriction enzymes that it expresses.
By “frequent” or “frequently” in a group of bacteria of interest is meant that at least 10, 20, 30, 40, 50, 60, 70, 75, 80, 85, 90, 95 or 99% of the bacteria of the group encode the restriction enzyme.
The vector according to the invention, preferably included into a delivery vehicle, preferably a bacteriophage capsid, preferably comprises no more than 100 restriction sites. In a preferred embodiment, the vector according to the invention, preferably included in a delivery vehicle, comprises no more than 10 restriction sites. In a most preferred embodiment, the vector according to the invention, preferably included in a delivery vehicle, does not comprise any restriction site.
The present invention also concerns a nucleic acid vector, as defined above, for use in in vivo delivery of a nucleic acid of interest, as defined above, into a targeted receiver bacterial cell, said nucleic acid of interest producing a given effect on said targeted receiver bacterial cell,
wherein said vector comprises:
wherein said vector is devoid of antibiotic resistance marker.
The vector of the invention comprises a conditional origin of replication which is inactive in the targeted receiver bacterial cell but is active in a donor bacterial cell.
In the context of the invention, a “conditional origin of replication” refers to an origin of replication whose functionality may be controlled by the presence of a specific molecule.
In a particular embodiment, the conditional origin of replication is an origin of replication, the replication of which depends upon the presence of one or more given protein, peptid, RNA, nucleic acid, molecule or any combination thereof.
In a particular embodiment, the replication of said origin of replication may further depend on a process, such as transcription, to activate said replication.
In the context of the invention, said conditional origin of replication is inactive in the targeted receiver bacterial cell because of the absence of said given protein, peptid, RNA, nucleic acid, molecule or any combination thereof in said receiver bacterial cell.
In a particular embodiment, said conditional origin of replication is active in said donor bacterial cell because said donor bacterial cell expresses said given protein, peptid, RNA, nucleic acid, molecule or any combination thereof. In a particular embodiment, said protein, peptid, RNA nucleic acid, molecule or any combination thereof is expressed in trans in said donor bacterial cell.
By “in trans” is meant herein that said protein, peptid, RNA, nucleic acid, molecule or any combination thereof is not encoded on the same nucleic acid molecule as the one comprising the origin of replication. In a particular embodiment, said protein, peptid, RNA, nucleic acid, molecule or any combination thereof is encoded on a chromosome or on a plasmid. In a particular embodiment, said plasmid comprises an antibiotic resistance marker. In an alternative embodiment, said plasmid is devoid of antibiotic resistance marker.
Since said conditional origin of replication is inactive in the targeted receiver bacterial cell because of the absence of said given protein, peptid, RNA, nucleic acid, molecule or any combination thereof in said receiver bacterial cell, said conditional origin of replication may be selected depending on the specific receiver bacterial cell to be targeted.
The conditional origin of replication used according to the present invention may originate from plasmids, bacteriophages or PICIs which preferably share the following characteristics: they contain in their origin of replication repeat sequences, or iterons, and they code for at least one protein interacting with said origin of replication (i.e. Rep, protein O, protein P, pri) which is specific to them.
By way of example, mention may be made of the conditional replication systems of the following plasmids and bacteriophages: RK2, R1, pSC101, F, Rts1, RSF1010, P1, P4, lambda, phi82, phi80.
In a particular embodiment, said conditional origin of replication is selected from the group consisting of the R6Kλ DNA replication origin and derivatives thereof, the IncPa oriV origin of replication and derivatives thereof, ColE1 origins of replication modified to be under an inducible promoter, and origins of replication from phage-inducible chromosomal islands (PICIs) and derivatives thereof.
In a particular embodiment, said conditional origin of replication is an origin of replication present in less than 50%, or less than 40%, less than 30%, less than 20%, less than 10% or less than 5% of the bacteria of the host microbiome.
In another particular embodiment, said conditional origin of replication comprises or consists of a sequence less than 80% identical, in particular less than 70%, less than 60%, less than 50%, less than 40%, less than 30%, less than 20%, less than 10%, less than 5% or less than 1% identical to the sequences of the origins of replication of the bacteria of the host microbiome, in particular of the bacteria representing more than 50%, more particularly more than 60%, more than 70%, more than 80%, more than 90% or more than 95% of the host microbiome.
In the context of the invention, the term “phaqe-inducible chromosomal islands” or “PICIs” are mobile genetic elements having a conserved gene organization, and encode a pair of divergent regulatory genes, including a PICI master repressor. Typically, in Gram-positive bacteria, left of rpr, and transcribed in the same direction, PICIs encode a small set of genes including an integrase (int) gene; right of rpr, and transcribed in the opposite direction, the PICIs encode an excision function (xis), and a replication module consisting of a primase homolog (pri) and optionally a replication initiator (rep), which are sometimes fused, followed by a replication origin (ori), next to these genes, and also transcribed in the same direction, PICIs encode genes involved in phage interference, and optionally, a terminase small subunit homolog (terS).
In a particular embodiment, said conditional origin of replication is an origin of replication derived from phage-inducible chromosomal islands (PICIs).
The present inventors indeed designed herein a particular conditional origin of replication derived from PICIs.
The present inventors showed that it is possible to derive novel conditionally replicative plasmids, in particular based on the primase-helicase and origin of replication from PICIs. These origins may be relatively rare in target strains, and more advantageously the primase-ori pair may be unique for each PICI, significantly reducing the possibility of undesired recombination or payload spread events. They can further be modified to further limit recombination chances and remove restriction sites to bypass target bacteria defense systems.
In a particular embodiment, said conditional origin of replication is derived from the origin of replication from the PICI of the Escherichia coli strain CFT073, disclosed in Fillol-Salom et al. (2018) The ISME Journal 12:2114-2128.
In a particular embodiment, said conditional origin of replication is the primase ori from the PICI of the Escherichia coli strain CFT073, typically of sequence SEQ ID NO: 4.
In another particular embodiment, said conditional origin of replication is the primase ori from he PICI of the Escherichia coli strain CFT073, devoid of at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 11, at least 12, at least 13, at least 14, at least 15 or at least 16 restriction site(s) selected from the group consisting of GAAABCC, GCCGGC, RCCGGY, GCNGC, TWCANNNNNNTGG (SEQ ID NO: 5), TGGCCA, ACCYAC, YGGCCR, AGACC, GCWGC, GGGANGC, GKAGATD, GCCGGYYD, GGCYAC, RGCCGGYYD, and VGCCGGYBD.
In a particular embodiment, said conditional origin of replication is the primase ori from the PICI of the Escherichia coli strain CFT073, devoid of the restriction site GAAABCC. Preferably, said conditional origin of replication is of sequence SEQ ID NO: 6.
In another particular embodiment, said conditional origin of replication is the primase ori from he PICI of the Escherichia coli strain CFT073 devoid of the restriction sites selected from the group consisting of GAAABCC, GCCGGC, RCCGGY, GCNGC, TWCANNNNNNTGG (SEQ ID NO: 5), TGGCCA, ACCYAC, YGGCCR, AGACC, GCWGC, GGGANGC, GKAGATD, GCCGGYYD, GGCYAC, RGCCGGYYD, and VGCCGGYBD. Preferably, said conditional origin of replication is of sequence SEQ ID NO: 7.
In a particular embodiment, wherein said origin of replication is derived from phage-inducible chromosomal islands (PICIs), said conditional origin of replication is active in said donor bacterial cell because said donor bacterial cell expresses a rep protein, in particular a primase-helicase, in particular a primase-helicase of sequence SEQ ID NO: 8, typically encoded by a nucleic acid comprising or consisting of the sequence SEQ ID NO: 9.
The inventors demonstrated that these specific conditional origins of replication were particularly compatible with lambda-based packaging, leading to sufficiently high titers (>1010/mL) required for microbiota-related applications.
In a particular embodiment, the vector of the invention comprises or consists of the sequence SEQ ID NO: 10. In another particular embodiment, the vector of the invention comprises or consists of the sequence SEQ ID NO: 11.
In a particular embodiment, when said vector is a phagemid, said origin of replication may be derived from a microorganism which is different from the one that is used to encode the structural elements of the capsid packaging said phagemid.
In a particular embodiment, said vector is located inside a bacterial delivery vehicle. Preferably, the vector located inside a delivery vehicle is a phagemid and the delivery vehicle is a bacterial virus particle or a capsid.
As used herein, the term «delivery vehicle» refers to any vehicle that allows the transfer of a vector or payload into a bacterium.

The present invention thus also concerns a bacterial delivery vehicle, as defined above, for use in in vivo delivery of a nucleic acid of interest into a targeted receiver bacterial cell, as defined above, wherein said bacterial delivery vehicle comprises the vector of the invention.
In the context of the application, the term “donor bacterial cell” refers to a bacterial cell hosting a vector or a plasmid, to a production cell line or to a bacterium that is capable of transferring a conjugative plasmid to another bacterium.
The present invention also concerns a donor bacterial cell comprising the vector of the invention or producing the bacterial delivery vehicle of the invention, wherein said donor bacterial cell stably comprises the vector of the invention and is able to replicate said vector.
In a particular embodiment, when the conditional origin of replication of said vector is an origin of replication, the replication of which depends upon the presence of a given protein, peptid, nucleic acid, RNA, molecule or any combination thereof, said donor bacterial cell expresses said protein, peptid, nucleic acid, RNA, molecule or any combination thereof. Preferably, said protein, peptid, nucleic acid, RNA, molecule or any combination thereof is expressed in trans, as defined in the section “Conditional origin of replication” above.
In a particular embodiment, said donor bacterial cell stably comprises a nucleic acid encoding said protein, peptid, nucleic acid, RNA, molecule or any combination thereof.
In a particular embodiment, when said origin of replication is derived from phage-inducible chromosomal islands (PICIs), said conditional origin of replication is active in said donor bacterial cell because said donor bacterial cell expresses a rep protein, in particular a primase-helicase, in particular a primase-helicase of sequence SEQ ID NO: 8.
In a particular embodiment, said donor bacterial cell stably comprises a nucleic acid encoding said rep protein, in particular said primase-helicase, said nucleic acid typically comprising or consisting of the sequence SEQ ID NO: 9.
In a particular embodiment, said donor bacterial cell is a production cell line, in particular a cell line producing packaged phagemids including the vector of the invention.
Generation of packaged phagemids and bacteriophage particles by production cell lines are routine techniques well-known to one skilled in the art. In an embodiment, a satellite phage and/or helper phage may be used to promote the packaging of the vector in the delivery vehicles disclosed herein. Helper phages provide functions in trans and are well known to the man skilled in the art. The helper phage comprises all the genes coding for the structural and functional proteins that are indispensable for the phagemid to be packaged, (i.e. the helper phage provides all the necessary gene products for the assembly of the delivery vehicle). The helper phage may contain a defective origin of replication or packaging signal, or completely lack the latter, and hence it is incapable of self-packaging, thus only bacterial delivery particles carrying the vector or plasmid will be produced. Helper phages may be chosen so that they cannot induce lysis of the bacterial cells used for the delivery particle production. One skilled in the art would understand that some bacteriophages are defective and need a helper phage for payload packaging. Thus, depending on the bacteriophage chosen to prepare the bacterial delivery particles, the person skilled in the art would know if a helper phage is required. Sequences coding for one or more proteins or regulatory processes necessary for the assembly or production of packaged payloads may be supplied in trans. For example, STF, gpJ and gpH proteins may be provided in a plasmid under the control of an inducible promoter or expressed constitutively. In this case, the phage wild-type sequence may or not contain a deletion of the gene or sequence supplied in trans. Additionally, chimeric or modified phage sequences encoding a new function, like an engineered STF, gpJ or gpH protein, may be directly inserted into the desired position in the genome of the helper phage, hence bypassing the necessity of providing the modified sequence in trans. Methods for both supplying a sequence or protein in trans in the form of a plasmid, as well as methods to generate direct genomic insertions, modifications and mutations are well known to those skilled in the art.
In a particular embodiment, said helper phage comprises a nucleic acid sequence encoding a chimeric STF comprising or consisting of the sequence SEQ ID NO: 12, said nucleic acid sequence typically comprising or consisting of the sequence SEQ ID NO: 13, and said helper phage optionally further comprises a nucleic acid sequence encoding a chimeric gpJ variant comprising or consisting of the sequence SEQ ID NO: 14, said nucleic acid sequence typically comprising or consisting of the sequence SEQ ID NO: 15.
In a particular embodiment, said helper phage is a lambda prophage wherein (i) the nucleic acid encoding a wild-type STF protein has been replaced by a nucleic acid sequence encoding a chimeric STF comprising or consisting of the sequence SEQ ID NO: 12, said nucleic acid sequence typically comprising or consisting of the sequence SEQ ID NO: 13, (ii) the nucleic acid encoding a wild-type gpJ protein has been replaced by a nucleic acid sequence encoding a chimeric gpJ variant comprising or consisting of the sequence SEQ ID NO: 14, said nucleic acid sequence typically comprising or consisting of the sequence SEQ ID NO: 15, and (iii) the Cos site has been removed, and wherein optionally (iv) the helper prophage contains a mutation which prevents spontaneous cell lysis, such as the Sam7 mutation and (v) the helper prophage contains a thermosensitive version of the master cl repressor, such as the c1857 version.
In a particular embodiment, the donor bacterial cell of the invention comprises the above-defined helper phage.
The vector used in the method of modulation of the invention may be administered as such, in a bacterial delivery vehicle or through a donor bacterial cell delivering said vector to the receiver bacterial cell. Said vector, bacterial delivery vehicle or donor bacterial cell may be more particularly administered in the form of a pharmaceutical or cosmetic composition comprising said vector, bacterial delivery vehicle or donor bacterial cell and a pharmaceutically acceptable carrier.
Generally, for pharmaceutical or cosmetic use, the vector, bacterial delivery vehicle or donor bacterial cell may be formulated as a pharmaceutical or cosmetic preparation or compositions comprising at least one vector, bacterial delivery vehicle or donor bacterial cell, and at least one pharmaceutically or cosmetically acceptable carrier, diluent or excipient, and optionally one or more further pharmaceutically or cosmetically active compounds. Such a formulation may be in a form suitable for oral administration, for parenteral administration (such as by intravenous, intramuscular or subcutaneous injection or intravenous infusion), for topical administration, for administration by inhalation, by a skin patch, by an implant, by a suppository, etc. In a particular embodiment, said composition is for oral administration.

Packaged phagemids are being used to deliver a DNA payload to target bacteria with high efficiency. Features required for phagemid packaging are the presence of a packaging site and an origin of replication that is functional in the producer cell line.
The use of a constitutive origin of replication to produce packaged phagemids has several advantages, notably:
Since phages have a precise tropism towards the same or closely related species in which they are produced, the packaged phagemids derived from this phage, once their payloads delivered in the target bacteria, will keep replicating, unless the phage has been engineered to infect/inject in a new group of bacteria.
However, having a phagemid harbouring a constitutive origin of replication may pose some risks when used in a clinical, industrial, or non-contained setup:
For all these reasons, the inventors aimed to develop a conditional system of replication that encompasses all the advantages mentioned above while reducing the spread and recombination risks. Such a system needs to have the following features:
In the following examples, the present inventors developed PICI-based conditional origins of replication.
First, they verified how common the origin region is in bacterial genomes, to assess the possibility of undesired recombination or payload spread events.
Second, they developed a system with the primase and ori in trans (ori on the phagemid
Third, they tested in vitro killing of E. coli and compared it to the current generation of replicative payloads.
Finally, they assessed if the primase-origin was amenable to removal of undesired restriction sites.
In the following examples,
The 282 bp region right after the stop codon of the PICI-CFT073 primase (SEQ ID NO: 4) was used to BLAST against all sequenced Escherichia coli genomes, filtering to give up to 20,000 hits.
As shown in
It also needs to be noted that, under normal circumstances, the primase of the PICI is inactive, meaning that even if injection occurs in a strain containing this specific PICI, it will not replicate unless the cell is under a phage-induction state, which further reduces the chances of the introduced payload replicating when not desired.
As a comparison, performing a BLAST analysis with a non-conditional modified p15a-based origin of replication returns the hits shown in
884 sequences were found. It also needs to be noted that when sequencing strains, plasmids may be left out of the assembly if they are small (for example, the pOSAK found in STEC O157 strains), so the number of hits may be higher.
Next, the inventors performed the same search but this time using the Domain Bacteria to assess the presence of the PICI-ori in other non-E. coli species: 165 hits were found for the PICI origin while more than 2000 hits were found for the p15a-based origin (see
In conclusion the inventors showed that the primase-ori was a good candidate to reduce the risk of recombination and undesired replication in target and non-target bacteria since its occurrence, based on BLAST analyses, is 10 to 20 fold lower than a p15a-based origin; and for effective replication, the cell where the payload is injected will need to be undergoing active phage production for the PICI primase to be present.
Next, the inventors sought to develop a system in which the payload contains the 282-bp primase origin and the primase protein is supplied in trans (SEQ ID NO: 8 and SEQ ID NO: 9). To simplify the engineering process, the PICI primase gene was extracted from the genome of E. coli CFT073, cloned into a plasmid under the control of an inducible system and an RBS (ribosome-binding site) library generated. This series of plasmids were cloned in the lambda production strain s1965. Next, the inventors constructed a small payload harboring the primase-ori instead of the p15a-based origin of replication to yield the 2.3 kb payload p1319 (SEQ ID NO: 16). Since this plasmid is, in principle, non-replicative, competent cells of s1965 harboring the RBS library of inducible primase constructs were made, the p1319 plasmid transformed in them and plated in LB agar+kanamycin and chloramphenicol in the presence of the inducer DAPG (to induce the expression of the primase in trans). Next day, the inventors observed that the plates contained hundreds of colonies, suggesting that the primase-origin system in trans works (
Several clones were sequenced to verify that the p1319 plasmid contained no p15a-based origin and that they also contained an intact primase gene with an RBS coming from the library.
After that, 7 of these clones were grown overnight and lambda productions were carried out in the presence of kanamycin, chloramphenicol and DAPG. As a control, the inventors included the original 2.8 kb plasmid containing a derivative of the p15a origin of replication to compare titers (p1220, SEQ ID NO: 17)
To verify the sequence of the RBS variants obtained, the plasmid encoding the inducible primase in the 7 clones tested was miniprepped and sequenced (SEQ ID NO: 18 to 24). They were also transformed into MG1655 cells (s003): these strains were used to verify the titers obtained, since the payloads should not be replicative in the absence of the primase protein supplied in trans.
As can be seen on
Finally, the inventors tested if the primase-ori containing payloads could replicate in MG1655 strains without the primase plasmid in trans. To do this, serial 5X dilutions of the primase-ori containing plasmids coming from the production strains with different primase RBS, plus a p15a-origin control, were transduced into a dense culture (OD600˜0.8) of MG1655 and plated on LB agar plates containing chloramphenicol. As can be seen on
In conclusion, PICI primase and origin can be stably maintained in production strains, are compatible with lambda-based phagemids packaging judging by the titers obtained and the payloads are dependent on the presence of its cognate primase for active replication and maintenance in target strains.
Next, the inventors tested if sequence-specific killing mediated by the Cpf1 nuclease would still occur in cells transduced by packaged phagemids. Since the cells will lose the plasmid by division, it was ignored if the initial burst of expression of the nuclease circuit would still be sufficient to achieve killing at a similar MOI as the one observed with a constitutive origin of replication.
To do this, the inventors constructed a large plasmid (˜12 kb) exchanging the p15a-based origin of replication by the primase origin. This plasmid targets the lacZ gene (p1322, SEQ ID NO: 25) and also contains a chloramphenicol marker. Since it was ignored if the RBS strength would need to be modified to replicate a large plasmid, the inventors transformed this plasmid into the production strain s1965 harboring an inducible primase RBS library in trans, as done for the initial, smaller payload. Next day, the inventors observed that the plates contained hundreds of colonies. One of these colonies was picked, sequenced to verify that the payload contained the primase-ori, the RBS of the primase in trans sequenced (SEQ ID NO: 26) and packaged phagemids were produced. As a control, the inventors produced the same phagemid containing a p15a-based origin of replication (p780, SEQ ID NO: 27) from the same production strain.
In this case, since the payload targets the MG1655 strain, the inventors verified the titers of the production in a derivative of MG1655 lacking the lacZ gene (s248) and containing the primase RBS 3 plasmid in trans (p1321).
Titers of both packaged phagemids whose payloads comprise constitutive and conditional origins of replication were undistinguishable, of about 1.5×108/μL after 10× concentration, suggesting that this approach is also valid for larger payloads.
Next, the inventors tested if killing of a target strain with packaged phagemids would be possible in the absence of selection and active replication of the payload, as the inventors already demonstrated with p15a-based origins. To do this, a culture of E. coli MG1655 was grown in LB+CaCl2 to an OD600 of about 0.8 and diluted in LB+CaCl2 to an OD=0.025. The packaged phagemids targeting lacZ and containing the p15a-based origin (control) or the primase origin were serially diluted 3×; this approach allowed for testing different MOIs. 90 μL of cells were added to each well containing a packaged phagemid dilution. After 30 min-incubation at 37° C., 10× dilutions of each reaction were performed, 10 μL plated on LB agar plates and incubated overnight at 37° C.
As can be seen in
In conclusion, conditional origins of replication based on PICIs allow for production at high titers of large payloads (˜12 kb) and nuclease-mediated killing of a target strain in the absence of selection and primase protein.
Finally, the inventors tested if the PICI origins of replication were amenable to removal of restriction sites present in certain target strains: the presence of such sites may completely abolish nuclease-specific killing since the payload will be degraded in the target strain before the nuclease gene is expressed.
To do this, the inventors analyzed the 282-bp PICI origin and found that it contains the O157 restriction site GAAABCC (GAAAGCC). The inventors modified this site within the origin and obtained the sequence GAAAGCa (small cap represents the mutation introduced) which should not be recognized by O157 strains. The modified PICI origin (SEQ ID NO: 6) was then cloned into ˜12 kb payloads containing a Cpf1 nuclease circuit targeting the lacZ gene as mentioned in Example 3 (p1326, SEQ ID NO: 28) and also a quadruplex crRNA guide targeting stx1 and stx2 genes (p1327, SEQ ID NO: 29).
The inventors previously designed a bacterial cell line producing an engineered lambda-based capsid, comprising a chimeric 1A2 gpJ protein and a chimeric STF-V10[Helix], able to inject efficiently in O157 strains (s15816), so these two plasmids were transformed in this production strain containing the primase RBS 3 in trans.
Colonies were readily obtained, which suggested that the mutation introduced in the origin does not affect the ability of the PICI primase to recognize and replicate it. Sequencing results verified the presence of a modified, deltaGAAABCC primase origin of replication.
Packaged phagemids were produced from these two strains and titrated on a variant of MG1655 recognized by this specific packaged phagemid, supplemented with a plasmid encoding the primase RBS variant 3 (s18241).
As can be seen on
Finally, two killing experiments were performed in O157 strains as described above for MG1655:
Briefly, cell cultures were brought to an OD600=0.025 and packaged phagemids serially diluted 1:3. 90 μL of cell cultures were added to the packaged phagemid dilutions, incubated for 30 min at 37° C., and serial 10× dilutions to allow for cell count were performed. 10 μL of each dilution were then plated on LB agar.
As can be seen on
The present example demonstrates efficient decolonization in vivo by specifically killing bacteria bearing six genes using a packaged phagemid with a conditional origin of replication.
Materials and Methods
Streptomycin-treated mice were orally administered with either a target bacterial strain (hereafter referred to as ‘Target strain’) or a mutant of the same bacterial strain deleted for a specific gene of interest, namely a stx gene (hereafter referred to as ‘Non-Target strain’) to establish a durable intestinal colonization with these bacterial strains.
A plasmid of sequence SEQ ID NO: 10, carrying a conditional origin of replication of sequence SEQ ID NO: 7, and coding for a nuclease and its guide targeting the stx gene mentioned above, was packaged into an engineered lambda-based capsid, comprising a chimeric 1A2 gpJ protein and a chimeric STF-V10[Helix] (1A2-V10 packaged phagemid).
Mice colonized with either strain were given 100 μl of packaged phagemids (approximately 1012 particles) along with 100 μl of a buffer (sucrose and bicarbonate in water) aimed at temporarily neutralizing the gastric pH. A separate group of mice colonized with the Target strain received only the buffer, to account for natural changes in colonization levels over the time of the experiment.
The bacterial colonization levels were measured non-invasively by plating dilutions of stool recovered from each animal individually onto agar plates.
These levels were compared before treatment was initiated (termed ‘T0’) and 8 hours after the treatment (termed ‘T8h’), and the change in colonization between T8h and T0 was calculated for each animal, and expressed as logarithmic change (see
Results
The pH-neutralizing buffer alone had no effect on the Target strain colonization levels, whereas the packaged phagemids caused a 3.5-log reduction in bacterial burden recovered from the stool 8 hours after oral administration. As expected, the packaged phagemids had no effect on colonization levels of the Non-target strain, demonstrating the specificity of packaged phagemids towards their target sequence.
These results thus demonstrate that an efficient in vivo killing of targeted bacteria can be achieved by delivering in said targeted bacteria, packaged phagemids with a conditional origin of replication, which is not active in the targeted bacteria, said phagemids being this incapable to replicate in said targeted bacteria.
This example presents a method for the base editing of the nucleic acid sequence encoding®-lactamase (SEQ ID NO: 30) on the E. coli MG1655 genome after phagemid transduction in vitro using a payload comprising a conditional origin of replication of sequence SEQ ID NO: 7, based on a primase-helicase.
The non-replicative payload comprises an adenine base editor (ABE8e), a transcribed guideRNA targeting the active site of the p-lactamase gene (K71E) on the genome, a lambda packaging sequence, a chloramphenicol resistance marker, and the conditional origin of replication of sequence SEQ ID NO: 7. Production of lambda phagemids, packaged inside a bacterial delivery vehicle comprising an A8 gpJ protein and an EB6 STF protein for delivery into E. coli MG1655, resulted in titers of 6.7×106 transduction units per μl (tu/μl).
Transduced cells were plated on LB plates 2 hours post transduction at different multiplicity of infections (MOI). The next day, 96 individual colonies for each MOI were spotted on LB and LB (carbenicillin) plates in order to analyse the base editing efficiency.
