Nucleic acid probes to ureaplasma

Abstract

Hybridization assay probes are described which are able to distinguish Ureaplasma and known strains or serotypes of the species Ureaplasma urealyticum found in humans from other related organisms.

Description

FIELD OF THE INVENTION

The invention described and claimed herein relates to the design and use of nucleic acid probes capable of detecting organisms of the genus Ureaplasma, and known strains or serotypes of the species Ureaplasma urealyticum, in test samples, e.g., from urogenital and endocervical specimens, tissue samples, amniotic and other body fluids, and from cultures.

BACKGROUND OF THE INVENTION

Two single strands of deoxyribo- ("DNA") or ribo-("RNA") nucleic acid, formed from nucleotides, (including the bases adenine (A), cytosine (C), thymidine (T), guanine (G), uracil (U), or inosine (I)), may hybridize to form a double-stranded structure held together by hydrogen bonds between pairs of complementary bases. Generally, A is hydrogen bonded to T or U, while G or I are hydrogen bonded to C. Along the chain, classical base pairs AT or AU, TA or UA, GC, or CG are present. Additionally, some mismatched base pairs (e.g., AG, GU) may be present.

Bringing together two single strands of nucleic acid containing sufficient contiguous complementary bases, under conditions which will promote their hybridization, results in double-stranded nucleic acid. Under appropriate conditions, DNA/DNA, RNA/DNA, or RNA/RNA hybrids can form.

A probe is generally a single-stranded nucleic acid sequence complementary to some degree to a nucleic acid sequence sought to be detected ("target sequence"). A probe may be labeled with a reporter group moiety such as a radioisotope, a fluorescent or chemiluminescent moiety, or with an enzyme or other ligand which can be used for detection. Background descriptions of the use of nucleic acid hybridization to detect particular nucleic acid sequences are given in Kohne, U.S. Pat. No. 4,851,330 issued Jul. 25, 1989, and by Hogan et al., International Patent Application No. PCT/US87/03009, entitled "Nucleic Acid Probes for Detection and/or Quantitation of Non-Viral Organisms," both references hereby incorporated by reference herein. Hogan et al., supra, describe methods for determining the presence of a non-viral organism or a group of non-viral organisms in a sample (e.g., sputum, urine, blood and tissue sections, food, soil and water).

The genera Ureaplasma and Mycoplasma are prokaryotes and comprise the taxonomic Mollicutes class. Mollicutes lack a bacterial cell wall and have a small genome size. They are considered one of the smallest of the free-living microorganisms. Ureaplasma are unique among Mollicutes because of their characteristic ability to metabolize urea. There are fourteen known serotypes of U. urealyticum (Stemke and Robertson, Diagn. Microbiol. Infect. Dis. 31: 311 (1985)). The fourteen serotypes can be divided into at least two subspecies ("biotypes") based upon restriction fragment length polymorphism ("RFLP") of U. urealyticum genomic DNA (Harasawa et al., Abstract S30-6 UIMS Meeting, Osaka Japan (1990), and Robertson et al., J. Clin. Microbiol. 31: 824 (1993)), or based upon rRNA sequences (Hammond et al., Abstract D17. Session 60, American Society for Microbiology General Meeting, (1991)).

U. urealyticum is commonly found in the human urogenital tract but has been implicated in a wide spectrum of pathologies. Several studies have implicated U. urealyticum as a possible etiologic agent in diseases affecting adult males, fetuses and infants. Brunner et al., Yale J. Biol. Med. 56: 545 (1983), identified U. urealyticum as the etiologic agent responsible for nongonococcal urethritis (NGU) in approximately 30 percent of adult males tested who had NGU. Cassell et al., Pediatr. Infect. Dis. 5: S247 (1986), implicated U. urealyticum as a possible cause of chorioamnionitis, which could in turn adversely affect the outcome of pregnancy and the health of neonates. Stagno et al., Pediatrics 68: 322 (1981), found U. urealyticum in 21% of infants with pneumonia and found the association of U. urealyticum with pneumonia to be "statistically significant." Waites et al., Lancet 8575: 17 (1988), found U. urealyticum in 8 percent of the cerebrospinal fluid specimens taken from a high-risk population of newborn infants (100 predominantly pre-term infants). According to these investigators U. urealyticum was the most common organism isolated of those sought. U. urealyticum has also been implicated in a number of other pathogenic states including septic arthritis (Lee et al., Arthritis and Rheumatism 35: 43 (1992)).

Standard microbiological techniques generally identify U. urealyticum by observing the hydrolysis of urea. These techniques usually involve inoculating both a complex broth medium and an agar medium containing urea and other nutrients with a freshly obtained specimen (Brunner et al., supra).

Sci., 23: 618 (1987), describe the use of whole chromosomal DNA probes for detection of Ureaplasma in genital specimens; Ohse and Gobel, Israel J. Med. Sci. 23: 352 (1987) describe hybridization of U. urealyticum rRNA genes to cloned DNA of the E. coli rRNA operon; Gobel and Stanbridge ("Detection of Mycoplasma by DNA Hybridization", EPO application number 86304919.3, publication number 0 250 662) mention biological probes for detecting Mycoplasmas or prokaryotes in general, or specific Mycoplasma and eubacterial species; Gonzales et al.

SUMMARY OF THE INVENTION

The featured invention discloses and claims novel oligonucleotide probes which are either targeted to a specific Ureaplasma nucleic acid target sequence or consist essentially of a specified nucleic acid sequence. The probes function by hybridizing to target U. urealyticum rRNA and/or rRNA gene sequences under stringent hybridization assay conditions. Thus, the probes can distinguish the genus Ureaplasma, including clinically significant U. urealyticum serotypes, from their known closest phylogenetic neighbors (Mycoplasma) and from other microorganism inhabitants of the human urogenital tract. Accordingly, the probes may be used in an assay to detect and/or quantitate Ureaplasma and U. urealyticum organisms.

Species of Mycoplasma found in humans include M. genitalium, M. pneumoniae and M. hominis. M. pneumoniae appears to be the most closely related Mycoplasma to U. urealyticum. M. genitalium is very similar in nucleic acid sequence to M. pneumoniae and has been isolated from the human genital tract. M. hominis is the most commonly isolated Mycoplasma from the genital tract.

Thus, in a first aspect, the invention described herein features hybridization assay probes able to selectively hybridize to a Ureaplasma target nucleic acid sequence. A Ureaplasma target nucleic acid sequence is a nucleic acid sequence present in Ureaplasma, preferably U. urealyticum nucleic acid, or a sequence complementary thereto. Preferably, the target nucleic acid sequence is not present in closely related Mycoplasma (e.g., M. pneumoniae). Sequences complementary to a target sequence may be generated by target amplification techniques such as polymerase chain reaction (PCR) or transcription mediated amplification (e.g., Kacian and Fultz, entitled "Nucleic Acid Amplification Methods", EPO application number 90307503.4; and Kacian et al., supra entitled "Nucleic Acid Sequence Amplification Method, Composition and Kit."

The featured probes can detect U. urealyticum and distinguish the genus Ureaplasma and known strains or serotypes of U. urealyticum found in humans from other bacteria including the phylogenetic closely related M. pneumoniae.

A hybridization assay probe is comprised of an oligonucleotide having a nucleic acid sequence sufficiently complementary to hybridize, under stringent hybridization assay conditions, to a 5S, 16S, or 23S rRNA, or to the corresponding ribosomal DNA ("rDNA") nucleic acid sequence, or to a nucleic acid sequence complementary thereto, of U. urealyticum. Stringent hybridization assay conditions, refer to conditions wherein a specific probe hybridizes with target nucleic acid (e.g., rRNA of Ureaplasma) and not another nucleic acid present in the test sample from either other microorganisms (e.g., Mycoplasma pneumonia) or humans. The probes are preferably 10 to 100 nucleotides in length.

By "probe" is meant to exclude naturally occurring nucleic acids. Purified oligonucleotide probes may be produced by techniques known in the art such as chemical synthesis and by in vitro or in vivo expression from recombinant nucleic acid molecules, e.g., retroviral vectors.

An oligonucleotide is made of nucleotide subunits covalently joined together. The sugar groups of the nucleotide subunits may be ribose, deoxyribose, or modified derivatives thereof such as O-methyl ribose. The nucleotide subunits may by joined by linkages such as phosphodiester linkages, modified linkages, or by non-nucleotide moieties that do not prevent hybridization of the oligonucleotide. Modified linkages include those linkages in which a standard phosphodiester linkage is replaced with a different linkage, such as a phosphorothioate linkage, or methylphosphonate linkage. When used as a hybridization assay probe, the oligonucleotide preferably contains a reporter group such as acridinium ester or a radioisotope to help identify hybridization of the probe to its target sequence.

In a related aspect, the invention described herein features hybridization assay probes able to selectively hybridize to a U. urealyticum nucleic acid target sequence present on either biotype 1 or biotype 2. The claimed target sequence is present in only one of the biotypes. Thus, an oligonucleotide probe directed to either biotype 1 or biotype 2 target site can distinguish between the biotypes.

In another related aspect, hybridization assay probes having a specific nucleic acid sequences complementary to rRNA or rDNA of Ureaplasma, are described. The probes are useful for detecting and/or quantitating Ureaplasma which may be present. These probes are complementary to a region of rRNA or rDNA which varies between Ureaplasma and Mycoplasma. Specific probes able to hybridize to Ureaplasma nucleic acid and distinguish Ureaplasma from Mycoplasma, comprise, consist essentially of, or consist of the sequences (written 5' to 3'):

Preferably, helper probe are used to facilitate the hybridization of the assay probe to its target nucleic acid sequence.

The phrases "consists essentially of" or "consisting essentially of" mean that the probe is provided as an oligonucleotide which hybridizes under stringent hybridization assay conditions to a target nucleic acid sequence of a particular organism and preferably does not hybridize with Mycoplasma described herein. A hybridization probe may be linked to other nucleic acids which do not affect hybridization. Generally, it is preferred that the probe be between 10 and 100 (most preferably between 15 and 50) nucleotides in length. Additionally, the probe may be provided in a vector.

For the listed probes, two sets of stringent hybridization assay conditions were used. One set comprised hybridization at 60.degree. C. for one hour in a solution containing 0.095 M lithium succinate pH 5, 0.31 M lithium lauryl sulfate, 1.5 mM ethylenediaminetetraacetic acid (EDTA), 1.5 mM ethylene glycol bis (beta-amino ethyl ether) N, N, N', N' tetraacetic acid (EGTA). After the one hour, hybrids were separated from unhybridized probe by binding to magnetic amine microspheres in a solution containing 0.76 M sodium borate pH 7.5, 6% Triton at 60.degree. C. for ten minutes and washed once in a solution containing 80 mM sodium borate pH 10.4 at room temperature.

Another set of stringent hybridization assay conditions was comprised of hybridization in 0.05 M lithium succinate pH 5, 0.6 M LiCl, 1% (w/v) lithium lauryl sulfate, 10 mM EDTA, 10 mM EGTA at 60.degree. C. for 15 minutes, followed by the addition of 300 .mu.l of 0.6 M sodium borate pH 8.5, 1% Triton X-100 at 60.degree. C. for 5-7 minutes. Additional sets of stringent hybridization conditions can be determined based upon techniques known in the art and the present disclosure.

In another aspect, specific probes able to distinguish between different biotypes are described. Specific probes able to hybridize to a nucleic acid sequence present in only one Ureaplasma biotype comprise, consist essentially of, or consist of the sequences (written 5' to 3'):

SEQ ID NO. 121: CAACACCGAC TCGTTCGAGC SEQ ID NO. 122: CAACACCGAC CCATTCGG and RNA equivalents thereto (SEQ ID NOs: 126 and 127), oligonucleotides complementary thereto (SEQ ID NOs: 131 and 132), and RNA equivalents to the oligonucleotides complementary thereto (SEQ ID NOs: 136 and 137). Preferably, a helper probe is used to facilitate the hybridization of the assay probe to its target nucleic acid sequence.

In another aspect, specific helper probe oligonucleotide sequences have been determined. Helper probes are used to facilitate the rate of hybridization of a hybridization assay probe to its target nucleic acid as described by Hogan and Milliman, U.S. Pat. No. 5,030,557 entitled "Means and Method for Enhancing Nucleic Acid Hybridization," issued Jul. 9, 1991 and hereby incorporated by reference herein. Helper probes featured herein include: SEQ ID NOs. 1, 3, 4, 6, 7, 8, 9, 10, 12, 13, 15, 16, 18, 19, 21, 24, 25, 26, 27, 28, 30, 123, 124, 125; RNA equivalents thereto, SEQ ID NOs. 37, 40, 64, 67, 70, 73, 76, 79, 82, 85, 88, 91, 94, 97, 100, 103, 106, 109, 112, 115, 118, 128, 129, 130; oligonucleotides complementary thereto, SEQ ID NOs. 38, 41, 65, 68, 71, 74, 77, 80, 83, 86, 89, 92, 95, 98, 101, 104, 107, 110, 113, 116, 119, 133, 134, 135; and RNA equivalents to the oligonucleotides complementary thereto, SEQ ID Nos. 39, 42, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99, 102, 105, 108, 111, 114, 117, 120, 138, 139, 140.

Some oligonucleotide probes can be used as an assay probe or a helper probe (e.g., SEQ ID Nos. 8, 9, and 26, RNA equivalents thereto, SEQ ID Nos. 37, 40, and 109, oligonucleotides complementary thereto, 38, 41, and 110, and RNA equivalents to the oligonucleotides complementary thereto 39, 42, and 111.

In another related aspect, the invention features compositions comprising a nucleic acid hybrid between a hybridization assay probe and a nucleic acid sequence substantially complementary thereto (probe:target). "Substantially complementary" means there is sufficient complementarity between the nucleic acids such that the hybrid is stable under stringent hybridization conditions. One use of the formed hybrid is to detect the presence of a target sequence. For example, acridinium ester ("AE") present in hybrids is resistant to hydrolysis in alkali solution whereas acridinium ester present in single-stranded nucleic acid is hydrolyzed in alkali solution (Arnold et al., entitled "Homogeneous Protection Assay," EPO application number 88308767.8, publication number 309230, hereby incorporated by reference herein). Thus, binding of AE-labeled probe to target can be detected, after hydrolysis of the unbound AE-labeled probe, by measuring chemiluminescence of acridinium ester remaining in the nucleic acid hybrid.

In other related aspects, methods are described for detecting Ureaplasma urealyticum and distinguishing Ureaplasma urealyticum from Mycoplasma such as Mycoplasma orale, Mycoplasma fermentans, Mycoplasma capricolum, Mycoplasma lipophilum, and Mycoplasma salivarium; distinguishing between Ureaplasma urealyticum biotype 1 and Ureaplasma urealyticum biotype 2; and detecting the presence of a Ureaplasma urealyticum nucleic acid sequence. These methods can be used on test samples obtained from human specimens.

The probes of this invention offer a rapid, non-subjective method of identifying and quantitating the presence of specific rRNA sequences unique to the genus Ureaplasma and all strains of U. urealyticum in a test sample.

Other features and advantages of the invention will be apparent from the following description of the preferred embodiments thereof and from the claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

We have identified preferred target sequences present in the rRNA or rDNA of U. urealyticum and designed specific oligonucleotide probes to these sequences and their complements which can be used to identify Ureaplasma. The probes can detect the genus Ureaplasma including U. urealyticum serotypes and distinguish them from their known and presumably most closely related taxonomic or phylogenetic neighbors. Probes are also described which distinguish U. urealyticum biotype 1 and biotype 2. Also described are methods using the featured probes or target sites.

In a preferred embodiment, the nucleic acid hybridization assay probes can distinguish U. urealyticum from M. genitalium, M. pneumoniae, or M. hominis. In another preferred embodiment, the nucleic acid hybridization probes can distinguish U. urealyticum from M. orale, M. fermentans, M. capricolum, M. lipophilum, and M. salivarium. These Mycoplasma have been isolated from humans.

Prokaryotic organisms (excluding viruses) contain rRNA genes encoding 5S rRNA, 16S rRNA and 23S rRNA. Using methods known to those skilled in the art, partial or full rRNA sequences of U. urealyticum and Mycoplasma were obtained. These sequences were aligned based on regions of sequence homology. Sequence variations were then identified from the aligned sequences and used as target sequences for hybridization assay probes.

Obtaining rRNA Sequences

Sequence information was obtained experimentally and from published information (see, Weisburg et al., J. Bacteriol 171: 6455 (1989); and Rogers et al., Proc. Natl. Acad. Sci., U.S.A., 82: 1160 (1985)). Experimental information was obtained by isolating and sequencing the ribonucleic acid from various organisms using sequence standard techniques known in the art. Nucleic acids were obtained using an oligonucleotide primer complementary to a conserved region of rRNA and extending the primer using reverse transcriptase. Nucleic acid sequences were then derived using the method of dideoxynucleotide chain termination. (e.g., Lane et al., Proc. Natl. Acad. Sci. U.S.A., 82: 6955 (1985)).

Probe Design And Hybridization Conditions

To facilitate the identification of nucleic acid sequences to be used as probes, the nucleotide sequences from different organisms were first aligned to maximize homology. Within the rRNA molecule there is a close relationship between secondary structure and function. This imposes restrictions on evolutionary changes in the primary sequence so that the secondary structure is maintained. For example, if a base is changed on one side of a helix, a compensating change is made on the other side to preserve the complementarity (this is referred to as co-variance). This allows two very different sequences to be aligned based on the conserved primary sequence and also on the conserved secondary structure elements. Potential target sequences for the hybridization probes were identified by noting variations in the homology of the aligned sequences.

The sequence evolution at each of the variable regions is mostly divergent. Because of the divergence, more distant phylogenetic relatives of U. urealyticum show greater variability to U. urealyticum at the variable region than phylogenetically closer relatives. We observed sufficient variation between U. urealyticum and strains of Mycoplasma found in the same sample to design several useful probes and identify preferred target sites.

Selective hybridization of probe to target can be accomplished by choosing the appropriate hybridization assay conditions and proper probe design. The stability of the probe:target nucleic acid hybrid should be chosen to be compatible with the assay and washing conditions so that hybrids will only form between highly complementary sequences. Manipulation of one or more of the different assay conditions determines the exact sensitivity and specificity of a particular probe. The following guidelines are useful for designing probes and determining stringent hybridization assay conditions.

Probes should be designed to have an appropriate melting temperature (T.sub.m). The appropriate T.sub.m can be obtained by varying the probe length and nucleotide composition (percentage of G+C versus A+T). The probe length and nucleotide composition should preferably be chosen to correspond to a T.sub.m about 2-10.degree. C. higher than the temperature at which the final assay will be performed.

In general, the optimal hybridization temperature for oligonucleotide probes of about 10-50 bases in length is approximately 5.degree. C. below the melting temperature for a given duplex. Incubation at temperatures below the optimum temperature may allow mismatched base sequences to hybridize and can therefore decrease specificity. The longer the probe, the more hydrogen bonding between base pairs and, in general, the higher the T.sub.m. Increasing the percentage of G and C also increases the T.sub.m because G-C base pairs exhibit additional hydrogen bonding and therefore greater thermal stability than A-T base pairs.

The preferred method to determine T.sub.m measures hybridization using a Hybridization Protection Assay (HPA) according to Arnold et al., supra entitled "Homogeneous Protection Assay." T.sub.m can be measured using HPA in the following manner. A probe:target hybrid is formed in a lithium succinate buffered solution (0.1 M lithium succinate buffer, pH 5.0, 2 mM EDTA, 2 mM EGTA, 10% (w/v) lithium lauryl sulfate) using an excess amount of target. Aliquots of the hybrid are then diluted in the lithium succinate buffered solution and incubated for five minutes at various temperatures starting below that of the anticipated T.sub.m (typically 55.degree. C.) and increasing in 2-5.degree. C. increments. This solution is then diluted with a mild alkaline borate buffer (0.15 M sodium tetraborate, pH 7.6, 5% (v/v) Triton X-100)) and incubated at a lower temperature (for example 50.degree. C.) for ten minutes. Under these conditions the acridinium ester attached to a single-stranded probe is hydrolyzed while the acridinium ester attached to hybridized probe is relatively protected from hydrolysis. Thus, the amount of acridinium ester remaining is proportional to the amount of hybrid and can be measured by the chemiluminescence produced from the acridinium ester upon the addition of hydrogen peroxide followed by alkali. Chemiluminescence can be measured in a luminometer (e.g., the Gen-Probe LEADER I or LEADER 50). The resulting data is plotted as percent of maximum signal (usually from the lowest temperature) versus temperature. The T.sub.m is defined as the temperature at which 50% of the maximum signal remains. In addition to the method above, T.sub.m may be determined by isotopic methods well known to those skilled in the art (e.g., Hogan et al., supra).

It should be noted that the T.sub.m for a given hybrid varies depending on the hybridization solution used. Factors such as the salt concentration, detergents, and other solutes can affect hybrid stability during thermal denaturation (J. Sambrook, E. F. Fritsch and T. Maniatis, Molecular Cloning, ch. 11 (2d ed. 1989)). Conditions such as ionic strength and incubation temperature under which a probe will be used to hybridize to target should be taken into account in constructing a probe. Thermal stability of hybrids increases as the ionic strength of the reaction mixture increases. On the other hand, chemical reagents which disrupt hydrogen bonds, such as formamide, urea, dimethyl sulfoxide and alcohols, can greatly reduce the thermal stability of the hybrids.

To ensure specificity of probe for target, it is desirable to have probes which hybridize only under conditions of high stringency. Under conditions of high stringency only highly complementary nucleic acid hybrids will form; hybrids without a sufficient degree of complementarity will not form. Accordingly, the stringency of the assay conditions determines the amount of complementarity needed between two nucleic acid strands to form a hybrid. Stringency is chosen to maximize the difference in stability between the hybrid formed with the target and other nucleic acid sequences.

Proper specificity may be achieved by minimizing the length of perfect complementarity to non-target organisms, avoiding G and C rich regions of homology to non-target sequences, and by constructing the probe to contain as many destabilizing mismatches to nontarget sequences as possible. Whether a probe sequence is useful to detect only a specific type of organism depends largely on the thermal stability difference between probe:target hybrids versus probe:nontarget hybrids. In designing probes, the differences in these T.sub.m values should be as large as possible (preferably 2.degree. C.-5.degree. C. or more).

The length of the target nucleic acid sequence, and accordingly the length of the probe sequence, can also be important. In some cases, there may be several sequences from a particular region, varying in location and length, which yield probes with the desired hybridization characteristics. In other cases, one sequence may be significantly better than another which differs merely by a single base. While it is possible for nucleic acids that are not perfectly complementary to hybridize, the longest stretch of perfectly homologous base sequence will generally determine hybrid stability. Oligonucleotide probes of different lengths and base composition may be used. Preferably, oligonucleotide probes are between 10 to 100 and, more preferably, between 15 to 50 bases in length.

Regions of rRNA known to form strong internal structures inhibitory to hybridization are less preferred target regions. Likewise, probes with extensive self-complementarity should be avoided. As explained above, hybridization is the association of two single strands of complementary nucleic acid to form a hydrogen-bonded double strand. It is implicit that if one of the two strands is wholly or partially involved in an intramolecular or intermolecular hybrid it will be less able to participate in the formation of a new intermolecular probe:target hybrid. In the case of rRNA, the molecule is known to form very stable intramolecular hybrids. By designing a probe so that a substantial portion of the targeted sequence is single-stranded, the rate and extent of hybridization between probe and target may be greatly increased.

An rDNA target occurs naturally in a double-stranded form as does the product of the polymerase chain reaction (PCR). These double-stranded targets are naturally inhibitory to hybridization with a probe and require denaturation prior to hybridization. Appropriate denaturation and hybridization conditions are known in the art (e.g., E. M. Southern, J. Mol. Biol. 98: 503 (1975)).

Probe Synthesis

Once a presumptive unique target sequence has been identified, a complementary oligonucleotide probe is selected and synthesized. Defined oligonucleotide probes may be produced by any of several well-known methods, including automated solid-phase chemical synthesis using cyanoethylphosphoramidite precursors (Barone et al., Nucleic Acids Research 12: 4051 (1984)), and as described in J. Sambrook, E. F. Fritsch and T. Maniatis, Molecular Cloning, ch. 11 (2d ed. 1989). Following synthesis and purification of a particular oligonucleotide probe, several different procedures may be utilized to determine the acceptability of the probe in terms of size and purity. One such procedure is polyacrylamide gel electrophoresis. Another such procedure is High Pressure Liquid Chromatography ("HPLC"). These procedures are well known to those skilled in the art.

Once synthesized, selected oligonucleotide probes may be labeled with a reporter group by any of several well-known methods (e.g., supra, J. Sambrook et al.). Useful labels include radioisotopes and non-radioactive reporting groups. Isotopic labels include .sup.3 H, .sup.35 S, .sup.32 P, .sup.125 I, .sup.57 Co and .sup.14 C. Isotopic labels can be introduced into the oligonucleotide by techniques known in the art such as nick translation, end labeling, second strand synthesis, the use of reverse transcription, and by chemical methods. When using radiolabeled probes, hybridization can be detected by autoradiography, scintillation counting, or gamma counting. The detection method selected will depend upon the particular radioisotope used for labeling.

Non-isotopic materials can also be used for labeling and may be introduced internally into the nucleic acid sequence or at the end of the nucleic acid sequence. Modified nucleotides may be incorporated enzymatically or chemically. Chemical modifications of the probe may be performed during or after synthesis of the probe, for example, through the use of non-nucleotide linker groups as described by Arnold et al., entitled "Non-Nucleotide Linking Reagents for Nucleotide Probes," EPO application number 88308766.0, publication number 313219, hereby incorporated by reference herein. Non-isotopic labels include fluorescent molecules, chemiluminescent molecules, enzymes, cofactors, enzyme substrates, haptens or other ligands.

Preferably, the probes are labeled with an acridinium ester. Acridinium ester labeling may be performed as described by Arnold et al., U.S. Pat. No. 5,185,439 entitled "Acridinium Ester Labeling and Purification of Nucleotide Probes" issued Feb. 9, 1993 and hereby incorporated by reference herein.

Helper Probes

The rate of nucleic acid hybridization of an assay probe with its target nucleic acid is enhanced by the use of "Helper Probes" as disclosed in Hogan and Milliman, U.S. Pat. No. 5,030,557 and hereby incorporated by reference herein. Helper probes are selected to hybridize to nucleic acid sequences located near the region targeted by the assay probe. Hybridization of the helper probe alters the secondary and tertiary structure and thereby renders the targeted area of the nucleic acid more accessible for the detection probe. Helper probes to be used with the assay probes described herein include oligonucleotides having the following nucleotide sequences (written 5' to 3'):

EXAMPLES

Examples are provided below to illustrate different aspects and embodiments of the present invention. These examples are not intended in any way to limit the disclosed invention.

Probes specific for Ureaplasma were identified by sequencing with primers complementary to the 16S and 23S rRNAs of U. urealyticum T-960 (CX-8), or from published 5S sequences. The nucleic acid sequence from phylogenetically near neighbors, including M. genitalium, M. pneumoniae, M. iowae, M. muris, M. pirum and M. gallisepticum, were used as comparisons with the nucleic sequence from U. urealyticum to determine variable regions.

The following hybridization assay probe sequences are featured in the examples described below::

The probes were synthesized with a non-nucleotide linker as described by Arnold et al. supra, "Non-Nucleotide Linking Reagents For Nucleotide Probes," then labeled with a chemiluminescent acridinium ester as described by Arnold et al., supra, U.S. Pat. No. 5,185,439. The reactivity and specificity of the probes for U. urealyticum were demonstrated using a hybridization and separation format (Example 1, Tables 1-4) or a homogeneous assay format (Examples 2 and 3, Tables 5 and 6; Example 4, Tables 7 and 8). These procedures are described by Arnold et al., supra, "Homogeneous Protection Assay"; Arnold et al., "Polycationic Supports and Nucleic Acid Purification, Separation and Hybridization" EPO application number 88301839.2, publication number 0 281 390 (hereby incorporated by reference herein); and Arnold et al., Clin. Chem., 35:1588 (1989) (hereby incorporated by reference herein).

Results are given in relative light units (RLU). Probes were hybridized to a cell lysate or RNA purified according to J. Sambrook, E. F. Fritsch and T. Maniatis, Molecular Cloning (2d ed. 1989). Alternatively, lysates, especially of Mycobacteria, Gram positive organisms, or yeasts, could be obtained utilizing a method described by Murphy et al., "Method for Releasing RNA and DNA from Cells," EPO application number 87303641.2, publication number 288618, hereby incorporated by reference herein. The following examples describe hybridization assay probes targeted to U. urealyticum rRNA sequences, or the corresponding gene, and their use in a hybridization assay.

Example 1

This example illustrates the ability of a mixture containing acridinium ester-labeled probes targeted to Ureaplasma 16S rRNA to detect various Ureaplasma strains but not other microorganisms. The mixture contained assay probes having SEQ ID NOs. 2, 5, 8, 9, 11, 14, 17 and 20, and the corresponding unlabeled "Helper Probes" (as described above).

Table 1 presents data using these probes with an excess of RNA released from liquid broth cultures containing 10.sup.6 -10.sup.8 organisms. An equal volume of cell lysate and hybridization solution containing 0.19 M lithium succinate pH 5, 0.62 M lithium lauryl sulfate, 3 mM ethylenediaminetetraacetic acid (EDTA), 3 mM ethylene glycol bis (beta-amino ethyl ether) N, N, N', N' tetraacetic acid (EGTA) were mixed and incubated at 60.degree. C. for one hour. Hybrids were then bound to magnetic amine microspheres (Advanced Magnetics, Inc., Cambridge, Mass.) in a solution containing 0.76 M sodium borate pH 7.5, 6% Triton and washed once in a solution containing 80 mM sodium borate pH 10.4. The chemiluminescence associated with the particles, from the hybridized acridinium ester-labeled probes, was measured in a luminometer equipped with automatic injection of 0.1% hydrogen peroxide in 1 mM nitric acid, followed by injection of a 1N sodium hydroxide solution. RLU from a hybridization reaction containing 1 ng of non-target RNA was subtracted from the values shown. The data in Table 1 show that the probes hybridize to known strains or serotypes of U. urealyticum found in humans as well as to U. cati, U. diversum and U. gallorale of animal origin.

Table 2 shows that the probes distinguish Ureaplasma from several closely related Mycoplasma, Acholeplasma, or Spiroplasma species. A net RLU value greater than 300 RLU was considered a positive reaction. An all-bacteria/yeast probe mixture was used as a control to demonstrate the presence of bacterial nucleic acid (data not shown). Hogan et al., supra, entitled "Nucleic Acid Probes for Detection and/or Quantitation of Non-Viral Organisms," gives examples of suitable all-bacteria/yeast probe mixtures. The all-bacteria probe used in the examples described herein is a derivative of all-bacteria probe No. 7 described by Hogan et al., (the all-bacteria probe used in the examples described herein is shifted so that it is four nucleotides shorter on the 5' end but 5 bases longer on the 3' end probe than the Hogan probe No. 7). The yeast probe is a derivative of fungal probe No. 1 described in Hogan et al.

Table 3 shows that the assay probe mixture distinguishes Ureaplasma from members of a panel of urogenital microbes. The all-bacteria/yeast probe mixture was also used as a control in this experiment.

Table 4 shows that the assay probes distinguish Ureaplasma from twenty-seven bacterial genera representing a phylogenetic cross section of microorganisms. Again, the all-bacteria/yeast probe mixture was used as a control in this experiment.

Example 2

Hybridization of an acridinium ester-labeled probe, targeted to a 23S rRNA U. urealyticum region, to U. urealyticum and other bacteria was evaluated. Lysate (L) or purified RNA was hybridized to probe SEQ ID NO. 29 and helper probes SEQ ID NOs. 28 and 30 in 0.05 M lithium succinate pH 5, 0.6 M LiCl, 1% (w/v) lithium lauryl sulfate, 10 mM EDTA, 10 mM EGTA at 60.degree.

The Ureaplasma sample contained 1 .mu.g of U. urealyticum rRNA.

As shown in Table 5, probes targeted to 23S rRNA U. urealyticum readily distinguish U. urealyticum from other organisms including Mycoplasma.

Example 4

This example describes probes which can distinguish biotype 1 from biotype 2. In the course of probe development it was observed that one probe gave signals substantially lower for biotype 1 lysates than biotype 2 lysates. This suggested sequence variability in the probe region. To identify probe sequences targeted to a particular biotype several strains of Ureaplasma urealyticum were analyzed. Using the sequence information, biotype specific probes SEQ. ID. NOs. 121 and 122 were synthesized and labeled with acridinium ester. The probes were hybridized to rRNA from 18 strains of Ureaplasma urealyticum as described in Example 2 and the data is presented in Table 7. The signal obtained with the all-bacteria/yeast probe mix provides a quantitative indication of the amount of rRNA in each sample. The biotype 1 probe reacted only with biotype 1 strains; the biotype 2 probe reacted only with biotype 2 strains.

A similar experiment was performed to investigate the specificity of the biotype probes against 18 closely related Mycoplasma species and two Spiroplasma species. Results shown in Table 8 are the net RLU (i.e., the RLU from sample tested minus the RLU from a negative control sample). As seen in Table 8, the biotype-specific Ureaplasma urealyticum probes reacted only with their respective specific biotype strains and did not cross-react with any of the other closely related organisms.

No. 141), 50 mM Tris-HCl, pH 7.6, 25 mM KCl, 17.5 mM MgCl.sub.2, 5 mM dithiothreitol, 2 mM spermidine trihydrochloride, 6.5 mM rATP, 2.5 mM rCTP, 6.5 mM rGTP, 2.5 mM rUTP, 0.2 mM DATP, 0.2 mM dCTP, 0.2 mM dGTP, 0.2 mM dTTP, 600 U MuMLV reverse transcriptase and 400 U T7 RNA polymerase (Kacian et al., supra, entitled "Nucleic Acid Sequence Amplification Method, Composition, and Kit"). The reaction was monitored by removing aliquots at various time points between 15 minutes and 4 hours and assaying for the product using two 5S rRNA probes of the same sense as the target rRNA (SEQ. ID. Nos. 59, 110) and helper probes (SEQ. ID. Nos. 104, 107) using conditions described in Example 2.

The data shown in Table 9 demonstrates the ability of assay probes targeted to nucleic acid sequences of the opposite sense as the rRNA of the organism to detect the product from a target amplification procedure. As the amplification time increased, more target sequence was produced resulting in increased signal from probe detection.

The data shown in the various examples described above confirm that the novel probes herein described and claimed are capable of distinguishing Ureaplasma from its known nearest phylogenetic neighbors. The data also demonstrates that probes have been designed which can be used to distinguish Ureaplasma biotypes from each other and from nearest known phylogenetic neighbors. Furthermore, complementary oligonucleotide probes, i.e., those having the same sense as the target, are utilized to detect the products of target amplification procedures now being utilized to increase the detection sensitivity of assays for organisms.

Other embodiments are within the following claims.
