Multidrug resistant organisms (MDROs; “superbugs”), microorganisms that have developed resistance to one or more classes of antimicrobial agents, such as antibiotics, are emerging as serious global health threat. It is estimated that over 2 million people in the United States contract serious bacterial infections that are resistant to one or more antibiotics each year (CDC, Antibiotic Resistance Threats in the United States, 2013. Publication No. CS239559-B). Treatment options for subjects with MDROs are extremely limited; prevention of transmission is critical. The most important factor contributing to the generation and propagation of MDROs is the use and overuse/misuse of antibiotics and it is thought that the problem will increase in severity as further pathogenic organisms with antibiotic resistance arise (CDC, 2013; WHO 2017).

Suppressing or preventing undesired bacteria in a subject or suppressing or preventing colonization of bacteria in a particular region of the body can be challenging. Bacterial colonization may induce immune responses (local or systemic) in the subject, which may lead to serious disease. In particular, for multi-drug resistant organisms, or organisms that have acquired antibiotic resistance, elimination with many conventional therapeutics, such as antibiotics, may not be possible due to resistance or tolerance to the therapeutic. Additionally, it has been recently appreciated that intestinal colonization by bacteria of the oral microbiome may influence the immune environment of the intestine, such as induce Th1-dominated immune responses and lead to chronic inflammation and inflammatory conditions (see, e.g., Atarashi et al. Science (2017) 358 (359-365)). Normal bacterial colonization of different regions of the body, such as the oral cavity, may provide a reservoir of bacteria that can migrate and colonize other regions, such as the intestines.
Development of a live biotherapeutic product that is effective in promoting intestinal decolonization against multiple pathogens (e.g., both carbapenem-resistant Enterobacteriaceae and extended spectrum beta-lactamase-producing Enterobacteriaceae) has been challenging. Provided herein are compositions and methods for reducing/suppressing and/or preventing colonization by pathogenic organisms, such as multi-drug resistant organisms, for example carbapenem resistant Enterobacteriaceae (CRE) and extended spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae. Provided herein are compositions and methods for suppressing infection by pathogenic organisms. Provided herein are compositions and methods for treating infection by a pathogenic organism. Also provided herein are compositions and methods for inducing regulatory T cell (Treg) production in response to pathogenic organisms. Provided herein are compositions and methods for inducing production of short chain fatty acids (SCFAs) in response to pathogenic organisms. Also provided herein are compositions comprising purified bacterial mixture and taurine, which may further aid in the colonization of the microbiota by beneficial bacterial strains and/or reduction in colonization (resistance) to pathogens.
In some embodiments, the one or more of the bacterial strains of the compositions provided herein colonize or recolonize the intestinal tract or parts of the intestinal tract (e.g., the colon or the cecum) of the subject. Such colonization or recolonization may also be referred to as grafting. In some embodiments, the one or more of the bacterial strains of the compositions recolonize the intestinal tract (e.g., the colon or the cecum) of the subject, for example after another organism or population of organisms has been partially or completely removed (e.g., by antibiotic treatment). In some embodiments, one or more of the bacterial strains of the compositions recolonize the intestinal tract (e.g., the colon or the cecum) after one or more pathogenic organisms or other organism (e.g., bacteria that induce an immune response) has been removed. In some embodiments, the recolonization of the intestinal tract or parts thereof by the bacterial strains of the compositions described herein prevents or suppresses colonization by undesired organisms (e.g., pathogenic organisms, multi-drug resistant organisms, oral microbiome bacteria, bacteria that induce immune responses, pathobionts, bacteria that reduce Treg production, bacteria that reduce SCFA production).
In some embodiments, the one or more of the bacterial strains of the compositions can “outgrow” a pathogen or undesired bacteria, such as a pathogenic organism, for example carbapenem resistant Enterobacteriaceae (CRE) and/or extended spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae. Thus, in some embodiments, if a pathogen or undesired bacteria (e.g., pathogenic organisms, multi-drug resistant organism, for example carbapenem resistanct Enterobacteriaceae (CRE) and extended spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae) and one or more bacteria of compositions provided herein are both present in the intestinal tract (e.g., the colon or the cecum), the one or more bacteria of compositions provided herein grow faster (e.g., have a shorter doubling time) than the pathogen, thereby preventing the pathogen from accumulating in the intestinal tract (e.g., the colon or the cecum). In some embodiments, the one or more bacteria of compositions provided herein grow faster than the pathogen in an otherwise intact or complete microbiome. In some embodiments, the one or more bacteria of compositions provided herein grow faster than the pathogen in a depleted microbiome (e.g., following antibiotic treatment). In some embodiments, the faster growth results because the one or more bacteria of the compositions provided herein are better at grafting in the intestinal tract (e.g., the colon or the cecum). In some embodiments, the faster growth results because the one or more bacteria of the compositions provided herein are better at metabolizing nutrients present in the intestinal tract (e.g., the colon or the cecum). In some embodiments, the compositions of bacterial strains provided herein prevent or inhibit replication of the pathogen. In some embodiments, the compositions of bacterial strains provided herein induce death of (kill) the pathogen. In some embodiments, the bacterial strains of the compositions provided herein can treat pathogenic infections, because of the synergy between the bacterial strains.
In some embodiments, the bacterial compositions described herein prevent recolonization by a pathogen or undesired bacteria (e.g., pathogenic organisms, multi-drug resistant organisms, for example carbapenem resistanct Enterobacteriaceae (CRE) and extended spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae). For example, in some embodiments, the pathogen or undesired bacteria have been reduced or eliminated from the subject, for example, using a first therapeutic agent (such as an antibiotic), and the bacterial compositions described herein are administered to prevent recolonization of the subject. In some embodiments, the bacterial compositions described herein reduce or eliminate a pathogen or undesired bacteria from the subject and prevent recolonization of the subject.
In some embodiments, the combination of bacterial strains of the compositions provided herein is superior in the use of nutrients when compared to the pathogen or undesired bacteria, thereby suppressing the growth of the pathogen or undesired bacteria. In some embodiments, the combination of bacterial strains of the compositions provided herein is superior in grafting when compared to the pathogen or undesired bacteria, thereby suppressing the growth of the pathogen or undesired bacteria. In some embodiments, the combination of bacterial strains of the compositions provided herein is superior in the use of nutrients and in grafting when compared to the pathogen or undesired bacteria, thereby suppressing the growth of the pathogen or undesired bacteria. In some embodiments, the combination of bacterial strains of the compositions provided herein inhibits the growth, survival, and/or colonization of the pathogen or undesired bacteria.
In some embodiments, the combination of bacterial strains of the compositions provided herein has antagonizing or inhibitory activity towards the pathogen or undesired bacteria, thereby inhibiting the growth, survival, and/or colonization of the pathogen or undesired bacteria. In some embodiments, at least one bacterial strain of the compositions provided herein has antagonizing or inhibitory activity towards the pathogen or undesired bacteria, thereby inhibiting the growth, survival, and/or colonization of the pathogen or undesired bacteria.
In some embodiments, the bacterial strains of the compositions provide a synergistic effect in colonizing specific niches in the intestinal tract (e.g., the colon or the cecum). In some embodiments, the synergistic effect is provided by the capacity of the combination to metabolize specific nutrients. In some embodiments, the synergistic effect is provided by the capacity of the combination to provide specific metabolites to the environment.
The bacterial strains used in the compositions provided herein generally are isolated from the microbiome of healthy individuals. In some embodiments, the compositions include strains originating from a single individual. In some embodiments, the compositions include strains originating from multiple individuals. In some embodiments, the bacterial strains are obtained from multiple individuals, isolated, and grown up individually. The bacterial compositions that are grown up individually may subsequently be combined to provide the compositions of the disclosure. It should be appreciated that the origin of the bacterial strains of the compositions provided herein is not limited to the human microbiome from a healthy individual. In some embodiments, the bacterial strains originate from a human with a microbiome in dysbiosis. In some embodiments, the bacterial strains originate from non-human animals or the environment (e.g., soil or surface water). In some embodiments, the combinations of bacterial strains provided herein originate from multiple sources (e.g., human and non-human animals).
In some embodiments, the bacteria of the compositions provided herein are anaerobic bacteria. In some embodiments, the bacteria of the compositions provided herein are obligate anaerobic bacteria.
In general, bacterial strains may be classified phylogenetically with other closely related strains and species based on their 16S rRNA (or 16S rDNA) nucleic acid sequence. Methods for determining the identity of specific bacterial species based on their 16S rRNA (or 16S rDNA) nucleic acid sequence are well known in the art (See, e.g., Jumpstart Consortium Human Microbiome Project Data Generation Working, G. PLOS One (2012) 7, e39315).

Aspects of the disclosure relate to bacterial strains with 16S rDNA sequences that have sequence identity to a nucleic acid sequence of any one of the sequences of the bacterial strains or species described herein. The terms “identical,” or percent “identity,” in the context of two or more nucleic acids or amino acid sequences, refer to two or more sequences or subsequences that are the same. Two sequences are “substantially identical” if two sequences have a specified percentage of amino acid residues or nucleotides that are the same (e.g., at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.6%, 99.7%, 99.8% or 99.9% sequence identity) over a specified region of a nucleic acid or amino acid sequence or over the entire sequence, when compared and aligned for maximum correspondence over a comparison window, or designated region as measured using one of the following sequence comparison algorithms or by manual alignment and visual inspection. Optionally, the identity exists over a region that is at least about 50 nucleotides in length, or more preferably over a region that is 100 to 500 or 1000 or more nucleotides in length. In some embodiments, the identity exists over the length the 16S rRNA or 16S rDNA sequence.
In some embodiments, the bacterial strain has at least 60%, at least 70%, at least 80%, at least 81%, at least 82%, at least 83%, at least 84%, at least 85%, at least 86%, at least 87%, at least 88%, at least 89%, at least 90%, at least 91%, at least 92%, at least 93%, at least 94%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, at least 99.5%, at least 99.6%, at least 99.7%, at least 99.8%, at least 99.9%, or up to 100% sequence identity relative to any of the strains or bacterial species described herein over a specified region or over the entire sequence. It would be appreciated by one of skill in the art that the term “sequence identity” or “percent sequence identity,” in the context of two or more nucleic acid sequences or amino acid sequences, refers to a measure of similarity between two or more sequences or portion(s) thereof.
Additionally, or alternatively, two or more sequences may be assessed for the alignment between the sequences. The terms “alignment” or percent “alignment” in the context of two or more nucleic acids or amino acid sequences, refer to two or more sequences or subsequences that are the same. Two sequences are “substantially aligned” if two sequences have a specified percentage of amino acid residues or nucleotides that are the same (e.g., at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.6%, 99.7%, 99.8% or 99.9% identical) over a specified region or over the entire sequence, when compared and aligned for maximum correspondence over a comparison window, or designated region as measured using one of the following sequence comparison algorithms or by manual alignment and visual inspection. Optionally, the alignment exists over a region that is at least about 50 nucleotides in length, or more preferably over a region that is 100 to 500 or 1000 or more nucleotides in length. In some embodiments, the identity exists over the length the 16S rRNA or 16S rDNA sequence.
For sequence comparison, typically one sequence acts as a reference sequence, to which test sequences are compared. Methods of alignment of sequences for comparison are well known in the art. See, e.g., by the local homology algorithm of Smith and Waterman (1970) Adv. Appl. Math. 2:482c, by the homology alignment algorithm of Needleman and Wunsch, J. Mol. Biol. (1970) 48:443, by the search for similarity method of Pearson and Lipman. Proc. Natl. Acad. Sci. USA 85:2444, 1988, by computerized implementations of these algorithms (GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group. Madison. WI), or by manual alignment and visual inspection (sec. e.g., Brent et al., Current Protocols in Molecular Biology, John Wiley & Sons, Inc. (Ringbou ed., 2003)). Two examples of algorithms that are suitable for determining percent sequence identity and sequence similarity are the BLAST and BLAST 2.0 algorithms, which are described in Altschul et al., Nuc. Acids Res. 25:3389-3402, 1977; and Altschul et al., J. Mol. Biol. 215:403-410, 1990, respectively.

In one aspect, the compositions comprise a fraction of a fecal sample. In some embodiments, the compositions comprise a non-spore forming fraction of a fecal sample. In some embodiments, the compositions comprise a spore forming fraction of a fecal sample.
In some embodiments, the compositions described herein comprise spore forming and non-spore forming bacterial strains. In some embodiments, the compositions described herein comprise spore forming bacterial strains. In some embodiments, the compositions described herein comprise only spore forming bacterial strains. In some embodiments, the compositions described herein comprise only non-spore forming bacterial strains. The spore-forming bacteria can be in spore form (i.e., as spores) or in vegetative form (i.e., as vegetative cells). In spore form, bacteria are generally more resistant to environmental conditions, such as heat, acid, radiation, oxygen, chemicals, and antibiotics. In contrast, in the vegetative state or actively growing state, bacteria are more susceptible to such environmental conditions, compared to in the spore form. In general, bacterial spores are able to germinate from the spore form into a vegetative/actively growing state, under appropriate conditions. For instance, bacteria in spore form may germinate when they are introduced in the intestine.
In some embodiments, at least one (e.g., 1, 2, 3, 4, 5, or more) of the bacterial strains in the composition is a spore former. In some embodiments, at least one (e.g., 1, 2, 3, 4, 5, or more) of the bacterial strains in the composition is in spore form. In some embodiments, at least one (e.g., 1, 2, 3, 4, 5, or more) of the bacterial strains in the composition is a non-spore former. In some embodiments, at least one (e.g., 1, 2, 3, 4, 5, or more) of the bacterial strains in the composition is in vegetative form. As discussed above, spore forming bacteria can also be in vegetative form. In some embodiments, at least one (e.g., 1, 2, 3, 4, 5, or more) of the bacterial strains in the composition is in spore form and at least one (e.g., 1, 2, 3, 4, 5, or more) of the bacterial strains in the composition is in vegetative form. In some embodiments, at least one bacterial strain that is considered able to form spores (i.e., a spore-former) is present in the composition in vegetative form. In some embodiments, at least one bacterial strain that is considered able to form spores is present in the composition both in spore form and in vegetative form.
In some embodiments, the compositions comprise bacterial strains that are spore forming bacterial strains. In some embodiments, the compositions comprise bacterial strains that are non-spore forming bacterial strains. In some embodiments, the compositions comprise bacterial strains that are spore forming bacterial strains and bacterial strains that are non-spore forming bacterial strains. In some embodiments, the compositions comprise a mixture of bacterial strains wherein at least 10% of the bacterial strains are spore forming bacterial strains, at least 20% of the bacterial strains are spore forming bacterial strains, at least 30% of the bacterial strains are spore forming bacterial strains, at least 40% of the bacterial strains are spore forming bacterial strains, at least 50% of the bacterial strains are spore forming bacterial strains, at least 60% of the bacterial strains are spore forming bacterial strains, at least 70% of the bacterial strains are spore forming bacterial strains, at least 80% of the bacterial strains are spore forming bacterial strains, at least 90% of the bacterial strains are spore forming bacterial strains bacteria or up to 100% of the bacterial strains are spore forming bacterial strains. Whether a bacterial strain is a spore forming strain can be determined for instance by evaluating the genome of the bacterial strain for the presence of sporulation genes. However, it should be appreciated that not all bacteria that are predicted to encode spore forming genes can be made to sporulate. In addition, whether a bacterial strain is a spore forming strain can be determined by exposing the bacterial strain to stress conditions, e.g., heat or exposure to chemicals (e.g., ethanol or chloroform), that are known to induce sporulation.
It should be appreciated that spore forming bacteria can be in spore form or in vegetative form. In some embodiments of the compositions provided herein, the spore forming bacteria are in spore form. In some embodiments, the spore forming bacteria are in vegetative form. In some embodiments, the spore forming bacteria are both present in spore form and in vegetative form. In some embodiments, compositions comprise spore forming bacteria and at least 10% of the spore forming bacteria are in spore format, at least 20% of the spore forming bacteria are in spore format, at least 30% of the spore forming bacteria are in spore format, at least 40% of the spore forming bacteria are in spore format, at least 50% of the spore forming bacteria are in spore format, at least 60% of the spore forming bacteria are in spore format, at least 70% of the spore forming bacteria are in spore format, at least 80% of the spore forming bacteria are in spore format, at least 90% of the spore forming bacteria are in spore format, or up to 100% of the spore forming bacteria are in spore format.
It is envisioned that the bacterial strains of the compositions provided herein are alive and will be alive when they reach the target area (e.g., the intestines). Bacterial spores are considered to be alive in this regard. In some embodiments, bacteria that are administered as spores may germinate in the target area (e.g., the intestines). It should further be appreciated that not all of the bacteria are alive, and the compositions can include a percentage (e.g., by weight) that is not alive. In addition, in some embodiments, the compositions include bacterial strains that are not alive when administered or at the time when the composition reaches the target area (e.g., the intestines). It is envisioned that non-living bacteria may still be useful by providing some nutrients and metabolites for the other bacterial strains in the composition.
Methods of inducing sporulation of spore-forming bacterial strains are well-known in the art (see, e.g., Paredes-Sabja et al., Trends Microbiol. (2011) 19(2):85-94). Generally, bacterial strains that are spore-formers can be made to go into spore form by stressing the bacterial strains. Non-limiting examples of stresses that can induce sporulation are an increase in temperature, change in the nutrients available and/or exposure to chemicals (e.g., ethanol or chloroform). It should be noted that bacteria that are non-spore formers, for instance because they are missing sporulation genes, cannot be made to sporulate by stress. To prepare compositions in which all the bacterial strains are in the spore form, the composition or bacterial cultures used to prepare the composition may be subjected to treatment to kill any bacteria not in spore form (e.g., in vegetative form), for example by exposing the composition to heat and chemically breaking down the non-spore bacteria. The bacteria in spore format can subsequently be separated from the non-spore bacteria for instance by filtration.
The amount of spores can be quantified using techniques known in the art. These techniques include phase contrast microscopy for enumerating spores using a hemocytometer. In addition, the viability of spores can be determined by plating the spores and growing the spores. For instance, spores can be plated in appropriate media and incubated in the anaerobic chamber for a period of time (e.g., 48-96 hrs.). Viability can subsequently be determined by quantifying the colony forming units which correspond to spores that germinated. For instance, spores can be plated on TCCFA plates (taurocholate, cycloserine, cefoxintin, fructose agar plates), in which taurocholate helps the spores to germinate. In addition, spores can be quantified using the dipicolinic assay (DPA assay). DPA is an agent that allows for spore selection and is a clear indicator of endospores. When complexed with terbium, bright green luminescence is observed.
In some embodiments, the compositions comprise bacterial strains that are non-spore forming bacterial strains. In some embodiments, the compositions comprise bacterial strains that are spore forming bacterial strains and bacterial strains that are non-spore forming bacterial strains. In some embodiments, the compositions comprise a mixture of bacterial strains wherein at least 10% of the bacterial strains are non-spore forming bacterial strains, at least 20% of the bacterial strains are non-spore forming bacterial strains, at least 30% of the bacterial strains are non-spore forming bacterial strains, at least 40% of the bacterial strains are non-spore forming bacterial strains, at least 50% of the bacterial strains are non-spore forming bacterial strains, at least 60% of the bacterial strains are non-spore forming bacterial strains, at least 70% of the bacterial strains are non-spore forming bacterial strains, at least 80% of the bacterial strains are non-spore forming bacterial strains, at least 90% of the bacterial strains are non-spore forming bacterial strains, or up to 100% non-spore forming bacterial strains.
In any of the compositions provided herein, the bacterial strains may be purified. In any of the compositions provided herein, the bacterial strains may be isolated. Any of the bacterial strains described herein may be isolated and/or purified, for example, from a source such as a culture or a microbiota sample (e.g., fecal matter). The bacterial strains used in the compositions provided herein generally are isolated from the microbiome of healthy individuals. However, bacterial strains can also be isolated from individuals that are considered not to be healthy. In some embodiments, the compositions include strains originating from multiple individuals.
As used herein, the term “isolated” refers to a bacterium or bacterial strain that has been separated from one or more undesired component, such as another bacterium or bacterial strain, one or more component of a growth medium, and/or one or more component of a sample, such as a fecal sample. In some embodiments, the bacteria are substantially isolated from a source such that other components of the source are not detected.
As also used herein, the term “purified” refers to a bacterial strain or composition comprising such that has been separated from one or more components, such as contaminants. In some embodiments, the bacterial strain is substantially free of contaminants. In some embodiments, one or more bacterial strains of a composition may be independently purified from one or more other bacteria produced and/or present in a culture or a sample containing the bacterial strain. In some embodiments, a bacterial strain is isolated or purified from a sample and then cultured under the appropriate conditions for bacterial replication, e.g., under anaerobic culture conditions. The bacteria that is grown under appropriate conditions for bacterial replication can subsequently be isolated/purified from the culture in which it is grown.
In some embodiments, the bacterial strains of the compositions provided herein are obligate anaerobes. In some embodiments, the bacterial strains of the compositions provided.
Aspects of the present disclosure are related to methods for suppressing undesired bacteria. As used herein, the term “suppressing” refers to any form of inhibiting undesired bacteria. In some embodiments, the methods described herein reduce/inhibit or prevent the colonization, replication, proliferation, and/or survival of the undesired bacteria (e.g., pathogenic organisms, multi-drug resistant organisms, for example carbapenem resistanct Enterobacteriaceae (CRE) and extended spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae). In some embodiments, the methods described herein directly or indirectly induce death of the undesired bacteria (e.g., pathogenic organism, multi-drug resistant organisms, for example carbapenem resistanct Enterobacteriaceae (CRE) and extended spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae).
Aspects of the present disclosure are related to methods for suppressing infection by a pathogenic organism in a subject. Aspects of the present disclosure are related to methods for reducing or preventing colonization by a pathogenic organism (e.g., bacterium, virus, fungus, or parasite) in a subject. Aspects of the present disclosure are related to methods for treating infection with a pathogenic organism. In some embodiments, the pathogenic organism is not multi-drug resistant. In some embodiments, the pathogenic organism resistant to one or more drugs (e.g., antibacterial, anti-viral, anti-fungal agent). In some embodiments, the pathogenic organism is multi-drug resistant. The methods described herein involve administering to a subject a therapeutically effective amount of any of the compositions described herein. As used herein, a “subject,” “individual,” and “patient” are used interchangeably, and refer to a vertebrate, preferably a mammal such as a human. Mammals include, but are not limited to, human primates, non-human primates or murine, bovine, equine, canine or feline species. In some embodiments, the subject is a human.
In some embodiments, any of the compositions described herein are effective in suppressing the replication, survival, and/or colonization of one or more pathogenic organism. In some instances, the pathogenic organism is susceptible to antibiotics, while in other instances, the pathogenic organism is resistant to antibiotics. In some embodiments, the pathogenic organism is a multi-drug resistant organism, which are described elsewhere herein. In some embodiments, the pathogenic organism is an oral microbiome bacterium. It should be noted that oral microbiome bacteria are not necessarily pathogenic, but may become so when located elsewhere, such as in the gastrointestinal tract. The amount of suppression of replication, survival, and/or colonization of the one or more pathogenic organism can be measured or identified using standard assays known in the art, some of which are further described and exemplified herein.
In some embodiments, administration of the compositions described herein reduces/inhibits or prevents the colonization, re-colonization, replication, proliferation, and/or survival of pathogenic organism, such as multi-drug resistant organisms. In some embodiments, administration of the compositions described herein allows for colonization of the gastrointestinal tract of the subject by the bacterial strain(s) of the compositions thereby preventing colonization by multi-drug resistant organisms.
In some embodiments, the pathogenic organism is a pathobiont, i.e., a potentially pathogenic organism which, under normal circumstances, lives as a symbiont.
In some embodiments, the subject is a carrier of a multi-drug resistant organism and is suffering from the effects of the infection. In some embodiments the subject is an asymptomatic carrier of a multi-drug resistant organism. In some embodiments, the subject has experienced recurrent or chronic colonization with a multi-drug resistant organism. In some embodiments, the subject is suffering from a first occurrence of a particular multi-drug resistant organism. In some embodiments, the subject is at risk of colonization with a multi-drug resistant organism, such as prior antibiotic use. In some embodiments, the subject has a risk factor associated with colonization with a multidrug resistant organism. In some embodiments, the subject has had a previous infection or colonization with a multi-drug resistant organism. In some embodiments, the subject has been treated with antibiotics which resulted in the recurrence of the multi-drug resistant organism.
In some embodiments, the subject is to undergo a procedure that puts the subject at a higher risk of colonization and the compositions are administered prophylactically. In some embodiments, the subject has a disease or disorder associated with use of a proton pump inhibitor, which may increase the likelihood of an oral bacterium migrating to the intestine. In some embodiments, the compositions provided herein are administered to a subject to lower the risk of becoming colonized with a multidrug resistant organism. In some embodiments, the bacterial compositions provided herein administered to a subject that is receiving a proton pump inhibitor.
Individuals may be at risk of acquiring a multi-drug resistant organism if they have recently received antimicrobials, are in an immunosuppressed state (e.g., on chemotherapy, have a malignancy, undergoing or received a transplant), have a chronic disease or inflammatory condition (such as diabetes, renal disease, etc.), are older, are undergoing hemodialysis, surgery or other invasive procedures, have indwelling device(s), and/or are living in a long-term care facility or are hospitalized. In some embodiments, the subject is colonized with a multi-drug resistant organism. Skin and mucosal colonization are common (Cassone et al., Curr Geriatr Rep. (2015) 4(1): 87-89), but multi-drug resistant organisms may also colonize the gastrointestinal (GI) tract and oral cavity, causing inflammation (Atarashi et al., Science (2017) 358, 359-365). Colonization can lead to significant infections, such as in the skin, lungs, urinary tract, or bloodstream, which may result in serious complications, including death (CDC, 2013). In some instances, multi-drug resistant organisms may be ingested, leading to consequences throughout the digestive system. In some embodiments, a multi-drug resistant organism may colonize the oral cavity.
In some embodiments, the multi-drug resistant organism is Vancomycin Resistant Enterococci (VRE), Carbapenem Resistant Enterobacteriaceae (CRE), Neisseria gonorrheae, Multidrug Resistant Acinetobacter, Campylobacter, Extended spectrum beta-lactamase (ESBL) producing Enterobacteriaceae, ESBL-producing Escherichia coli, Multidrug Resistant Pseudomonas aeruginosa, Salmonella, Drug resistant non-typhoid Salmonella, Drug resistant Salmonella Typhi, Drug resistant Shigella, Methicillin Resistant Staphylococcus aureus, Drug resistant Streptococcus pneumoniae, Drug resistant Tuberculosis, Vancomycin resistant Staphylococcus aureus, Erythromycin Resistant Group A Streptococcus, or Clindamycin resistant Group B Streptococcus. In some embodiments, the multi-drug resistant organism is Vancomycin Resistant Enterococci (VRE). In some embodiments, the multi-drug resistant organism is Carbapenem Resistant Enterobacteriaceae (CRE).
In some embodiments, the compositions described herein are effective in reducing or preventing colonization by more than one multi-drug resistant organism. In some embodiments, the compositions described herein are effective in treating infection of more than one multi-drug resistant organism. For example, in some embodiments, the compositions described herein are effective in reducing or preventing, or treating infection, with a carbapenem resistant Enterobacteriaceae (CRE) and Extended spectrum beta-lactamase (ESBL) producing Enterobacteriaceae,

The abundance of regulatory T cells (e.g., total Tregs or pathogenic organism-specific Tregs) can be assessed by any method known in the art, for example by detecting a cellular marker indicative of regulatory T cells (e.g., FoxP3), assessing a direct or indirect activity of regulatory T cells, and/or by measuring the production of one or more cytokines produced by regulatory T cells (e.g., IL-10).
Some aspects compositions and methods described herein increase production of short chain fatty acids (e.g., in the gastrointestinal tract of the subject). In some embodiments, the methods involve administering to a subject one or more compositions containing bacterial strains that produce short chain fatty acids. SCFAs are abundant in healthy subjects (e.g., subjects not having a pathogenic organism infection) and decreased in subjects having pathogenic organism infections (e.g., Clostridium difficile infections and rCDIs). Fecal matter transplant (FMT) have been shown to increase SCFA following rCDI (Seckatz, et al., Anaerobe (2018) 53: 64-73.
SCFA produced in the gastrointestinal tract are thought to function as signaling molecules between the gut microbiota and the host organism, with the SCFA playing a in local, intermediary and peripheral metabolism of the host. Sec, e.g., Morrison, et al. Gut Microbes (2016) 7(3): 189-200. In some embodiments, a damaged gut mucosal barrier can be repaired by providing SCFA.
Examples of SCFA include, without limitation, formic acid, acetic acid, butyric acid, isobutyric acid, valeric acid, or isovaleric acid. In some embodiments, the SCFA is butyric acid (butyrate).

In some embodiments, the subject is infected with a pathogenic organism. In some embodiments, the subject has a Clostridium difficile infection (CDI). In some embodiments, the CDI is recurrent (rCDI). rCDI is CDI that occurs more than once in the same subject and is associated with reduced short chain fatty acids (SCFAs), increased primary bile acids, and decreased secondary bile acids in the gut microbiota of the subject.
Bile acids are steroid acids that allow the digestion of dietary fats and oils by acting as surfactants that turn the fats and oils into micelles. Bile acids also act as hormones utilizing the farnesoid X receptor and GBPAR1. Primary bile acids are synthesized in the liver from cholesterol and a conjugated with either taurine or glycine prior to secretion. When the primary bile acids are secreted into the lumen of the intestine, bacteria partially dehydroxylate and remove the glycine or taurine groups, forming secondary bile acids.
Non-limiting examples of primary bile acids are cholic acid (CA), chenodeoxycholic acid (CDCA), glycocholic acid (GCA), glycochenodeoxycholic acid (GCDCA), glycodeoxycholic acid (GDCA), taurocholic acid (TCA), and turochenodeoxycholic acid (TCDCA). Non-limiting examples of secondary bile acids are deoxycholic acid (DCA), lithocholic acid (LCA), ursodeoxycholic acid (UDCA), taurodeoxycholic acid (TDCA), taurolithocholic acid (TLCA), and tauroursodeoxycholic acid (TUDCA).
Pathogenic organism infection, including Clostridium difficile infection and rCDI, are associated with increased primary bile acids and reduced secondary bile acids. The primary bile acids are reduced, and the secondary bile acids are increased following fecal matter transplant (FMT) (Seckatz, et al., Anaerobe (2018) 53: 64-73). In some embodiments, administration of the bacterial strains or a pharmaceutical composition as described herein reduces primary bile acids and/or increases secondary bile acids.
In some embodiments, the levels of primary bile acids are reduced by 10-fold to 100,000-fold following administration of the bacterial strains or the pharmaceutical composition. In some embodiments, the levels of primary bile acids are reduced by 10-fold to 1,000-fold following administration of the bacterial strains or the pharmaceutical composition. In some embodiments, the levels of primary bile acids are reduced 20-fold to 10,000-fold following administration of the bacterial strains or the pharmaceutical composition. In some embodiments, the levels of primary bile acids are reduced by 10-fold, 100-fold, 200-fold, 300-fold, 400-fold, 500-fold, 600-fold, 700-fold, 800-fold, 900-fold, 1,000-fold, 10,000-fold, 20,000-fold, 30,000-fold, 40,000-fold, 50,000-fold, 60,000-fold, 70,000-fold, 80,000-fold, 90,000-fold, or 100,000-fold following administration of the bacterial strains or the pharmaceutical composition.
In some embodiments, the levels of secondary bile salts are increased by 10-fold to 10,000-fold following administration of the bacterial strains or the pharmaceutical composition. In some embodiments, the levels of secondary bile acids are increased by 10-fold to 1,000-fold following administration of the bacterial strains or the pharmaceutical composition. In some embodiments, the levels of secondary bile acids are increased by 20-fold to 100-fold following administration of the bacterial strains or the pharmaceutical composition. In some embodiments, the levels of secondary bile acids are increased by 10-fold, 20-fold, 50-fold, 100-fold, 200-fold, 300-fold, 400-fold, 500-fold, 600-fold, 700-fold, 800-fold, 900-fold, 1,000-fold, 2,000-fold, 3,000-fold, 4,000-fold, 5,000-fold, 6,000-fold, 7,000-fold, 8,000-fold, 9,000-fold, or 1,000-fold following administration of the bacterial strains or the pharmaceutical composition.
In general, short chain fatty acids (SCFAs) are fatty acids containing six or less carbon atoms. SCFAs are produced when dietary fiber is fermented in the intestine. Non-limiting examples of SCFAs include hexanoate, pentanoate, butyrate, propionate, acetate, and formate. SCFAs are primarily absorbed in the portal vein following lipid digestion, and can affect the production of lipids, energy, and vitamins. Further, SCFAs play a critical role in maintaining intestinal epithelial cell membrane integrity for preventing pathogenic organism (e.g., Clostridium difficile) infection.
In one aspect, the disclosure provides methods comprising administration of multiple doses of the pharmaceutical compositions. In some embodiments, the disclosure provides methods comprising administration of antibiotic (e.g., vancomycin) followed by multiple doses of the pharmaceutical compositions. In some embodiments, administration of multiple doses of the pharmaceutical compositions described herein provides enhanced colonization (engraftment) of one or more bacterial strains of the pharmaceutical compositions as compared to administration of a single dose of the pharmaceutical composition. In some embodiments, administration of multiple doses of the pharmaceutical compositions described herein provides enhanced recovery of one or more bacterial strains of the pharmaceutical compositions as compared to administration of a single dose of the pharmaceutical composition. In some embodiments, administration of multiple doses of the pharmaceutical compositions described herein provides increased abundance of one or more bacterial strains of the pharmaceutical compositions as compared to administration of a single dose of the pharmaceutical composition. In some embodiments, administration of multiple doses of the pharmaceutical compositions described herein provides an increase in the number of subjects that were colonized with of all of bacterial strains of the pharmaceutical compositions as compared to administration of a single dose of the pharmaceutical composition. In some embodiments, administration of multiple doses of the pharmaceutical compositions described herein provides durable colonization (e.g., up to 6 months) of one or more bacterial strains of the pharmaceutical compositions as compared to administration of a single dose of the pharmaceutical composition. In some embodiments, administration of multiple doses of the pharmaceutical compositions described herein provides durable colonization (e.g., up to 6 months) of all of the bacterial strains of the pharmaceutical compositions as compared to administration of a single dose of the pharmaceutical composition. It should further be appreciated that administration of multiple dose my results in a combination of the results described. Thus, for example, in some embodiments, administration of multiple doses of the pharmaceutical compositions described herein provides enhanced colonization (engraftment) and increased rate of recovery of one or more bacterial strains of the pharmaceutical compositions as compared to administration of a single dose of the pharmaceutical composition.
In some embodiments, administration of multiple doses of the pharmaceutical compositions described herein provides enhanced colonization (engraftment) of one or more bacterial strains of the pharmaceutical compositions as compared to administration of a single dose of the pharmaceutical composition. Administration of multiple doses of the pharmaceutical composition may result in enhanced colonization (engraftment) and an increased abundance of each of the bacterial strains of the pharmaceutical composition. In some embodiments, administration of a single dose of the pharmaceutical composition results in the same or a similar level of engraftment (e.g., total bacteria) as administration of multiple doses of the pharmaceutical composition, however the engraftment may be dominated by one bacterial strain or only a subset of the bacterial strains of the pharmaceutical compositions.
Any of the methods described herein may involve administering an antibiotic to the subject prior to administration of the pharmaceutical compositions described herein. In some embodiments, the antibiotic is vancomycin, fidaxomycin or ridinilazole. Non-limiting examples of antibiotics that may be used in any of the methods provided herein include cephalosporin antibiotics cephalexin, cefuroxime, cefadroxil, cefazolin, cephalothin, cefaclor, cefamandole, cefoxitin, cefprozil, ceftobiprole, clindamycin, ceftriaxone, cefotaxime, cefazolin, cefoperazone, cefuroxime, cefmetazole, fluoroquinolone, ciprofloxacin, Levaquin, floxin, tequin, avelox, norflox, tetracycline, minocycline, oxytetracycline, doxycycline, amoxicillin, ampicillin, penicillin V, dicloxacillin, benzylpenicillin, carbenicillin, vancomycin, and methicillin, ertapenem, doripenem, imipenem/cilastatin, meropenem, clavulanate, tazobactam, piperacillin, ceftriaxone, cefotaxime, cefazolin, fluoroquinolone, imipenem, meropenem, metronidazole, fidaxomyxin, or ridinilazole.
In some embodiments, any of the methods described herein may further comprise administering vancomycin to the subject prior to administration of the pharmaceutical compositions described herein. In some embodiments, the method does not comprise administering an antibiotic to the subject prior to administration of the pharmaceutical compositions described herein. In some embodiments, the method does not comprise administering vancomycin to the subject prior to administration of the pharmaceutical compositions described herein. Vancomycin administration has been found to alter the composition of human gut microbiota. See, e.g., Reijnders et al. Cell Metabolism (2016) 24(1): 63-72. Without wishing to be bound by any particular theory, it is thought that administration of vancomycin may aid engraftment of the bacterial strain(s) of the pharmaceutical compositions described herein, for example by removing other microbes present in the gastrointestinal tract.
In some embodiments, the antibiotic (e.g., vancomycin) is administered to the subject once, as a single dose. In some embodiments, the antibiotic (e.g., vancomycin) is administered to the subject in multiple doses. In some embodiments, the antibiotic (e.g., vancomycin) is administered to the subject in at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or more doses. The multiple doses of the antibiotic (e.g., vancomycin) may be administered to the subject at regular intervals prior to administering any of the pharmaceutical compositions described herein. In some embodiments, each of the multiple doses of the antibiotic (e.g., vancomycin) are administered on consecutive days (e.g., first dose on day 1, second dose of day 2, third dose on day 3, etc.). In some embodiments, the antibiotic (e.g., vancomycin) is administered to the subject for 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or more consecutive days. In some embodiments, the antibiotic (e.g., vancomycin) is administered to the subject each day for three consecutive days. In some embodiments, the antibiotic (e.g., vancomycin) administered to the subject each day for five consecutive days.
In some embodiments, the antibiotic (e.g., vancomycin) administered to the subject each day for seven consecutive days. In some embodiments, the antibiotic (e.g., vancomycin) administered to the subject for one day. In any of the embodiments described herein, a subject may be administered one or more doses of a first antibiotic followed by one or more doses of a second antibiotic.
In some embodiments, a single dose, or the first dose in a treatment regimen of multiple doses, is administered, the same day as the administration of the final dose of the antibiotic (e.g., vancomycin). In some embodiments, a single dose, or the first dose in a treatment regimen of multiple doses, is administered, the day after administration of the final dose of the antibiotic (e.g., vancomycin). In some embodiments, a single dose, or the first dose in a treatment regimen of multiple doses, is administered, two days after administration of the final dose of the antibiotic (e.g., vancomycin). In some embodiments, the methods provided herein allow for a wash out day between the final dose of the antibiotic (e.g., vancomycin) and the first dose of the pharmaceutical composition. In some embodiments, a single dose, or the first dose in a treatment regimen of multiple doses, is administered, three days, four days, five days, six days, ten days or more, after administration of the final dose of the antibiotic (e.g., vancomycin). In some embodiments, the methods provided herein allow for multiple wash out days between the final dose of the antibiotic (e.g., vancomycin) and the first dose of the pharmaceutical composition.
Each dose of the antibiotic (e.g., vancomycin) may be the same amount of the antibiotic or may be a different amount of the antibiotic. In some embodiments, the antibiotic (e.g., vancomycin) is administered in an amount sufficient to allow for colonization of one or more of the bacterial strains of the pharmaceutical compositions described herein. In some embodiments, the subject is administered between about 50 mg and 1 g, 100 mg and 750 mg, 100 mg and 500 mg. 200 mg and 750 mg. 200 mg and 500 mg, 300 mg and 750 mg, 300 mg and 500 mg, 100 mg and 400 mg, 100 mg and 300 mg, 100 mg and 200 mg, 200 mg and 400 mg. 200 mg and 300 mg, or 450 mg to 550 mg of the antibiotic per day. As will be appreciated by one of skill in the art, the total amount of vancomycin administered to the subject per day may be administered in a single dose or between multiple doses, which in sum results in the total amount of the antibiotic per day.

In some embodiments, any of the methods described herein may further comprise administering a composition comprising taurine to the subject. In some embodiments, the composition comprising taurine is administered concomitantly with any of the pharmaceutical compositions comprising a purified bacterial mixture described herein. In some embodiments, the composition comprising taurine is administered prior to administration of any of the pharmaceutical compositions comprising a purified bacterial mixture described herein. In some embodiments, the composition comprising taurine is administered after administration of any of the pharmaceutical compositions comprising a purified bacterial mixture described herein. In some embodiments, the composition comprising taurine is administered prior to and after administration of any of the pharmaceutical compositions comprising a purified bacterial mixture described herein.
Taurine, also referred to as 2-aminoethanesulfonic acid, is an organic compound that is widely distributed in animal tissues and is a major constituent of bile and can be found conjugated to bile acids. Taurine may account for up to 0.1% of total human body weight and can be found in the large intestine, among other locations. The precise function of taurine in the physiological processes is not known, but without wishing to be bound by any particular theory, it is thought that taurine may help support muscle maintenance.
Taurine occurs naturally in fish and meat, and consumption in humans generally varies between 40 and 400 mg per day. However, in recent years, energy drinks for human consumption have included taurine. One example energy drink, marketed under the trademark Red Bull®, contains approximately 1000 mg of taurine per can (serving). High consumption of taurine is generally considered to be safe with no adverse effects noted from up to 3000 mg taurine per day.
Taurine administration has been found to alter the composition of mouse gut microbiota. It has recently been reported that infection may induce host taurine production and the expansion of taurine utilizers. Upon release of bile acids from the gallbladder into the gut, bacteria present in the gut may cleave taurine from bile acids, making the taurine available for use as an energy source. Bacteria, for example of the class Deltaproteobacteria, such as Biophila wadsworthia, utilize taurine in anaerobic respiration, and the expansion of Deltaproteobacteria following taurine administration is thought to aid in inhibiting intestinal colonization by Klebsiella pneumoniae and Citrobacter rodentium, a mouse model of pathogenic E. coli. Sec, e.g., Stacy et al. Cell. 2021 184(3):615-627.
As a result, gut microbiota from previously infected hosts were found to display enhanced resistance to infection. The microbiota from previously infected hosts has been associated with altered bile acid metabolism leading to the expansion of taxa that utilize the sulfonic acid, taurine. Indeed, it was reported that supplying exogenous taurine alone was sufficient to induce this alteration in microbiota function and enhance resistance. Mechanistically, taurine potentiates the microbiota's production of sulfide, an inhibitor of cellular respiration, which is key to host invasion by numerous pathogens. Sec, e.g., Stacy et al. Cell. 2021 184(3):615-627.
Without wishing to be bound by any particular theory, it is thought that administration of taurine may promote replication and/or aid engraftment of the bacterial strain(s) of the pharmaceutical compositions described herein, for example by serving as an energy source for bacteria present in the gastrointestinal tract or pharmaceutical composition.

In some embodiments, a bowel lavage may remove or aid in removing microbiota from the gastrointestinal tract of the subject, creating a niche for the bacterial strains of the compositions described herein. In some embodiments, the bowel lavage may be an oral bowel lavage or a rectal bowel lavage.
Methods of performing a bowel lavage are known in the art, and generally involve the rapid administration of large volumes of a solution, such as polyethylene glycol or a balanced electrolyte solution. A rectal bowel lavage can involve the administration of a solution or a suppository containing the pharmaceutical composition. A bowel lavage may be performed under doctor supervision, hospitalization, or at home.
Any of the compositions described herein, including the pharmaceutical compositions and food products comprising the compositions, may contain bacterial strains in any form, for example in an aqueous form, such as a solution or a suspension, embedded in a semi-solid form, in a powdered form or freeze dried form. In some embodiments, the composition or the bacterial strains of the composition are lyophilized. In some embodiments, a subset of the bacterial strains in a composition is lyophilized. Methods of lyophilizing compositions, specifically compositions comprising bacteria, are well known in the art. Sec, e.g., U.S. Pat. Nos. 3,261,761; 4,205,132; PCT Publications WO 2014/029578 and WO 2012/098358, herein incorporated by reference in their entirety. The bacteria may be lyophilized as a combination and/or the bacteria may be lyophilized separately and combined prior to administration. A bacterial strain may be combined with a pharmaceutical excipient prior to combining it with the other bacterial strain or multiple lyophilized bacteria may be combined while in lyophilized form and the mixture of bacteria, once combined may be subsequently be combined with a pharmaceutical excipient. In some embodiments, the bacterial strain is a lyophilized cake. In some embodiments, the compositions comprising the one or more bacterial strains are a lyophilized cake.
In some embodiments, one or more of the bacterial strains of the compositions, including pharmaceutical compositions and food products, has been spray-dried. In some embodiments, a subset of the bacterial strains is spray-dried. The process of spray-drying refers to production of dry powder from a liquid comprising bacterial compositions (Sec, e.g., Ledet, et al., Spray Draying of Pharmaceuticals in “Lyophilized Biologics and Vaccines” pages 273-294, Springer). In general, the process involves rapidly drying the bacterial compositions with a hot gas. A bacterial strain may be combined with a pharmaceutical excipient prior to combining it with the other bacterial strains or multiple spray-dried bacterial strains may be combined while in spray-dried form and the mixture of bacterial strains, once combined, may be subsequently combined with a pharmaceutical excipient.
The bacterial strains of the composition can be manufactured using fermentation techniques well known in the art. In some embodiments, the active ingredients are manufactured using anaerobic fermenters, which can support the rapid growth of anaerobic bacterial species. The anaerobic fermenters may be, for example, stirred tank reactors or disposable wave bioreactors. Culture media such as BL media and EG media, or similar versions of these media devoid of animal components, can be used to support the growth of the bacterial species. The bacterial product can be purified and concentrated from the fermentation broth by traditional techniques, such as centrifugation and filtration, and can optionally be dried and lyophilized by techniques well known in the art.
In some embodiments, the composition of bacterial strains may be formulated for administration as a pharmaceutical composition. The term “pharmaceutical composition” as used herein means a product that results from the mixing or combining of at least one active ingredient, such as any two or more purified bacterial strains described herein, and one or more inactive ingredients, which may include one or more pharmaceutically acceptable excipient.
An “acceptable” excipient refers to an excipient that must be compatible with the active ingredient and not deleterious to the subject to which it is administered. In some embodiments, the pharmaceutically acceptable excipient is selected based on the intended route of administration of the composition, for example a composition for oral or nasal administration may comprise a different pharmaceutically acceptable excipient than a composition for rectal administration. Examples of excipients include sterile water, physiological saline, solvent, a base material, an emulsifier, a suspending agent, a surfactant, a stabilizer, a flavoring agent, an aromatic, an excipient, a vehicle, a preservative, a binder, a diluent, a tonicity adjusting agent, a soothing agent, a bulking agent, a disintegrating agent, a buffer agent, a coating agent, a lubricant, a colorant, a sweetener, a thickening agent, and a solubilizer.
Pharmaceutical compositions disclosed herein can be prepared in accordance with methods well known and routinely practiced in the art (see e.g., Remington: The Science and Practice of Pharmacy, Mack Publishing Co. 20th ed. 2000). The pharmaceutical compositions described herein may further comprise any carriers or stabilizers in the form of a lyophilized formulation or an aqueous solution. Acceptable excipients, carriers, or stabilizers may include, for example, buffers, antioxidants, preservatives, polymers, chelating reagents, and/or surfactants. Pharmaceutical compositions are preferably manufactured under GMP conditions. The pharmaceutical compositions can be used orally, nasally or parenterally, for instance, in the form of capsules, tablets, pills, sachets, liquids, powders, granules, fine granules, film-coated preparations, pellets, troches, sublingual preparations, chewables, buccal preparations, pastes, syrups, suspensions, elixirs, emulsions, liniments, ointments, plasters, cataplasms, transdermal absorption systems, lotions, inhalations, aerosols, injections, suppositories, and the like. In some embodiments, the pharmaceutical compositions can be used by injection, such as by intravenous, intramuscular, subcutaneous, or intradermal administration.
Aspects of the present disclosure relate to administration of compositions comprising taurine. In some embodiments, a composition comprising any of the purified bacterial strains described herein may further comprise taurine. In such embodiments, administration of the composition results in administration to the subject of both the purified bacterial strains and taurine. In some embodiments, a composition comprising any of the purified bacterial strains described herein does not contain taurine. In some embodiments, a composition that is not the composition comprising the purified bacterial strains comprises taurine. In some embodiments, the methods involve administering to a subject a composition comprising purified bacterial strains and administering to the subject a second composition comprising taurine.
In some embodiments, the compositions comprising bacterial strains are formulated for delivery to the intestines (e.g., the small intestine and/or the colon). In some embodiments, the compositions comprising bacterial strains are formulated with an enteric coating that increases the survival of the bacteria through the harsh environment in the stomach. The enteric coating is one which resists the action of gastric juices in the stomach so that the bacteria of the composition therein will pass through the stomach and into the intestines. The enteric coating may readily dissolve when in contact with intestinal fluids, so that the bacteria enclosed in the coating will be released in the intestinal tract. Enteric coatings may consist of polymer and copolymers well known in the art, such as commercially available EUDRAGIT (Evonik Industries). (See e.g., Zhang, AAPS PharmSciTech (2016) 17(1): 56-67).
The compositions comprising bacterial strains may also be formulated for rectal delivery to the intestine (e.g., the colon). Thus, in some embodiments, compositions comprising bacterial strains may be formulated for delivery by suppository, colonoscopy, endoscopy, sigmoidoscopy or enema. A pharmaceutical preparation or formulation and particularly a pharmaceutical preparation for oral administration, may include an additional component that enables efficient delivery of the compositions of the disclosure to the intestine (e.g., the colon). A variety of pharmaceutical preparations that allow for the delivery of the compositions to the intestine (e.g., the colon) can be used. Examples thereof include pH sensitive compositions, more specifically, buffered sachet formulations or enteric polymers that release their contents when the pH becomes alkaline after the enteric polymers pass through the stomach. When a pH sensitive composition is used for formulating the pharmaceutical preparation, the pH sensitive composition is preferably a polymer whose pH threshold of the decomposition of the composition is between about 6.8 and about 7.5. Such a numeric value range is a range in which the pH shifts toward the alkaline side at a distal portion of the stomach, and hence is a suitable range for use in the delivery to the colon. It should further be appreciated that each part of the intestine (e.g., the duodenum, jejunum, ileum, cecum, colon and rectum), has different biochemical and chemical environment. For instance, parts of the intestines have different pHs, allowing for targeted delivery by compositions that have a specific pH sensitivity. Thus, the compositions provided herein may be formulated for delivery to the intestine or specific parts of the intestine (e.g., the duodenum, jejunum, ileum, cecum, colon and rectum) by providing formulations with the appropriate pH sensitivity. (See e.g., Villena et al., Int J Pharm (2015) 487 (1-2): 314-9).
Another embodiment of a pharmaceutical preparation useful for delivery of the compositions to the intestine (e.g., the colon) is one that ensures the delivery to the colon by delaying the release of the contents (e.g., the bacterial strains) by approximately 3 to 5 hours, which corresponds to the small intestinal transit time. In one embodiment of a pharmaceutical preparation for delayed release, a hydrogel is used as a shell. The hydrogel is hydrated and swells upon contact with gastrointestinal fluid, with the result that the contents are effectively released (released predominantly in the colon). Delayed release dosage units include drug-containing compositions having a material which coats or selectively coats a drug or active ingredient to be administered. Examples of such a selective coating material include in vivo degradable polymers, gradually hydrolyzable polymers, gradually water-soluble polymers, and/or enzyme degradable polymers. A wide variety of coating materials for efficiently delaying the release is available and includes, for example, cellulose-based polymers such as hydroxypropyl cellulose, acrylic acid polymers and copolymers such as methacrylic acid polymers and copolymers, and vinyl polymers and copolymers such as polyvinylpyrrolidone.
Additional examples of pharmaceutical compositions that allow for the delivery to the intestine (e.g., the colon) include bioadhesive compositions which specifically adhere to the colonic mucosal membrane (for example, a polymer described in the specification of U.S. Pat. No. 6,368,586) and compositions into which a protease inhibitor is incorporated for protecting particularly a biopharmaceutical preparation in the gastrointestinal tracts from decomposition due to an activity of a protease.
Another example of a system enabling the delivery to the intestine (e.g., the colon) is a system of delivering a composition to the colon by pressure change in such a way that the contents are released by utilizing pressure change caused by generation of gas in bacterial fermentation at a distal portion of the stomach. Such a system is not particularly limited, and a more specific example thereof is a capsule which has contents dispersed in a suppository base and which is coated with a hydrophobic polymer (for example, ethyl cellulose).
A further example of a system enabling the delivery of a composition to the intestine (e.g., the colon), is a composition that includes a coating that can be removed by an enzyme present in the gut (e.g., the colon), such as, for example, a carbohydrate hydrolase or a carbohydrate reductase. Such a system is not particularly limited, and more specific examples thereof include systems which use food components such as non-starch polysaccharides, amylose, xanthan gum, and azopolymers.
The compositions provided herein can also be delivered to specific target areas, such as the intestine, by delivery through an orifice (e.g., a nasal tube) or through surgery. In addition, the compositions provided herein that are formulated for delivery to a specific area (e.g., the cecum or the colon), may be administered by a tube (e.g., directly into the small intestine). Combining mechanical delivery methods such as tubes with chemical delivery methods such as pH specific coatings, allow for the delivery of the compositions provided herein to a desired target area (e.g., the cecum or the colon).
The compositions comprising bacterial strains are formulated into pharmaceutically acceptable dosage forms by conventional methods known to those of skill in the art. Dosage regimens are adjusted to provide the optimum desired response (e.g., the prophylactic or therapeutic effect). In some embodiments, the dosage form of the composition is a tablet, pill, capsule, powder, granules, solution, or suppository. In some embodiments, the pharmaceutical composition is formulated for oral administration. In some embodiments, the pharmaceutical composition is formulated such that the bacteria of the composition, or a portion thereof, remain viable after passage through the stomach of the subject. In some embodiments, the pharmaceutical composition is formulated for rectal administration, e.g. as a suppository.
