The present invention relates to nucleic acid probes useful for detecting and identifying nonviral infectious organisms in biological samples and for use in diagnosing diseases caused by such nonviral infectious organisms. In particular, the present invention relates to nucleic acid probes derived from rRNA genes of nonviral infectious organisms and useful for detecting and identifying those organisms, and compositions and kits useful for diagnosing infectious diseases, including these nucleic acid probes.

(Background)

Infectious diseases are diseases that occur when pathogens start to live in the blood, body fluids, and tissues, and may be life-threatening if accurate identification and proper treatment of causative organisms are not performed. More recently, the misuse of antibiotics has resulted in a reduction in the incidence of pathogens. Diagnostic methods for diagnosing infectious diseases are increasingly difficult. In particular, in the case of certain pathogens, including anaerobic bacteria, it causes a very fatal and serious disease in the human body, promptly diagnosing them and identifying the type of the pathogens are very important in the treatment. Due to this necessity, diagnostic methods for identifying microorganisms causing infectious diseases have been researched and developed for a long time. Significant advances have been made in detecting a large number of microorganisms over the past decade, but the diagnostic methods currently in use still require a lot of labor and are low in sensitivity and specificity.

Except for viruses, all prokaryotic organisms contain rRNA genes that encode homologs of prokaryotic 5S, 16S and 23S rRNA molecules. For eukaryotic cells, these rRNA molecules are 5S rRNA, 5.8S rRNA, 18S rRNA and 28S rRNA, which are substantially similar to those of prokaryotic cells. Many probes have been published for the specific targeting of rRNA subsequences of specific organisms or groups of organisms in biological samples. By using these nucleic acid probes in combination with well known polymerase chain reaction (PCR), many of these problems can be solved in conventional diagnostic methods. In nucleic acid probe technology for diagnosis, selection of target genes to be amplified is very important. In general, rRNA, in particular 23S rRNA gene and Internal Transcribed Spacer Region (ITS), are used, and nucleic acid probe sequences for these are advantageously suitable. It is known that the probability of cross-reaction with nucleic acids from other organisms under tightening conditions is low (P. Wattiau et. Al., Appl. Microbiol. Biotechnol., 56, 816-819, 2001; D, A. Stahlm et. al., J. Bacteriol., 172, 116-124, 1990; Boddinghaus. et.al., J. Clin., Microbiol., 28, 1751-1759, 1990; T. Rogall et al., J. Gen. Microbiol., 136, 1915-1920, 1990; T. Rogall, et.al., Int. J. System.Bacteriol., 40, 323-330, 1990; K. Rantakokko-Jalava et.al., J. Clin , Mirobiol., 38 (1), 32-39, 2000; Park et.al., J. Clin., Mirobiol., 38 (11), 4080-4085, 2000; A. Schmalenberger et.al, Appl. Microbiol.Biotechnol., 67 (8), 3557-3563, 2001; International Patent Publication WO98 / 55646, US Pat. No. 6025132 to Jannes et al., And US Pat. No. 6,277,577 to Rossau et al.).

However, for many pathogens the base sequence of the rRNA gene is in an unidentified state, and thus there remains a need to develop a probe with a high specificity to identify and derive the base sequence of the rRNA gene of such pathogen. In addition, although for some pathogens the nucleotide sequence of the rRNA gene is revealed in whole or in part, new nucleic acid probes capable of detecting such pathogens more specifically need to be developed.

Term Definition

The following definitions describe terms and expressions used in other aspects of the invention as described below.

A "isolated" nucleic acid molecule is one that is separated from other nucleic acid molecules present in the natural source of the nucleic acid. For example, with respect to genomic DNA, the term “isolated” includes nucleic acid molecules isolated from chromosomes to which genomic DNA is naturally bound.

"Probe" or "nucleic acid probe" refers to a single-chain oligonucleotide having a base sequence that is sufficiently complementary to the target base sequence to be detected and hybridizes.

"Composition" means that a probe complementary to a bacterial or fungal rRNA may be pure or combined with other probes. In addition, the probe may be combined with a salt or a buffer in a dried state, as a precipitate, in the form of an alcohol solution or an aqueous solution.

"Target" means a nucleic acid molecule from a biological sample having a sequence complementary to any of the probes according to the invention. The target nucleic acid may be single stranded or double stranded DNA (optionally obtained after amplification) or RNA and contains a sequence having at least partial complementarity with at least one probe oligonucleotide.

A "biological sample" is a sample of a clinical sample (eg, juice, saliva, blood, urine, etc.), environmental sample, bacterial colony, contaminated or pure culture, purified nucleic acid, etc., for which a target sequence of interest is to be detected. Point to.

"Polynucleic acid" corresponds to a single-stranded or double-stranded cDNA or genomic DNA or RNA in which at least 10, 20, 30, 40 or 50 nucleotides are contiguous. Polynucleic acids having a length of 100 or fewer nucleotides are often referred to as oligonucleotides. Single-chain polynucleic acid sequences are always represented from the 5 'end to the 3' end in the present invention.

"Oligonucleotide" generally refers to a nucleotide polymer consisting of about 10 to about 100 nucleotides. However, the length of the nucleotides may be 100 or more or 10 or less.

A “nucleotide” is the basic unit of nucleic acid consisting of phosphate groups, 5-carbosaccharides and nitrogen bases. 5-Tanose in RNA is ribose. The 5-saccharide in DNA is 2-deoxyribose. In the case of 5-nucleotides, the sugars contain hydroxyl groups (-OH) in 5-saccharide-2. The term also includes analogs of these basic units, such as methoxy groups at the 2 position of ribose.

"Homologous" is synonymous with identity, meaning that a polynucleic acid, for example 90% homology, exhibits 90% identical base pairs at the same position in the arrangement of the sequences.

"Hybridization" means the annealing of complementary sequences to a target nucleic acid (the sequence to be detected). The ability of two nucleic acid polymers, including complementary sequences, to find each other and hybridize through base pair interactions is a well known phenomenon.

"Primer" refers to a single stranded DNA oligonucleotide sequence that can serve as a starting point for the synthesis of extension products complementary to the nucleic acid backbone to be replicated. The length and sequence of the primers may be such that they can initiate the synthesis of extension products, preferably consisting of about 5 to 50 nucleotides. The specific length and sequence will be determined by the complexity of the desired DNA or RNA target as well as the conditions of primer use such as temperature and ionic strength.

"Tension" is used to describe the temperature and solvent composition during hybridization and subsequent processing. Under highly tightening conditions only highly complementary nucleic acid hybrids will be formed. In contrast, hybrids do not form when they lack a sufficient degree of complementarity. Thus, the tightening of the assay conditions determines the amount of complementarity required between the two nucleic acid backbones that form the hybrid. Contraction is chosen to maximize the difference in stability between the target and non-target nucleic acids and the hybrids formed and formed.

“Complementarity” is provided by the base sequence of the Japanese chain of DNA or RNA capable of forming hybrid or double-stranded DNA: DNA, RNA: RNA or DNA: RNA via hydrogen bonding between individual stranded Watson-Crick base pairs. It indicates the nature of being. Adenine (A) is usually complementary to thymine (T) or uracil (U) and guanine (G) is usually complementary to cytosine (C).

"Matched" refers to all pairs of two nucleotides that do not form normal Watson-Crick hydrogen bonds in a hybrid.

A "label" refers to any atom or molecule capable of providing a detectable (preferably quantifiable) signal and capable of binding to a nucleic acid. The label can provide a signal detectable by fluorescence, radioactivity, chromaticity, X-ray diffraction or absorption, magnetism, and the like.

A "hybrid" is a complex formed between two single-stranded nucleic acid sequences by Watson-Crick base pairs or non-standard base pairs between complementary bases.

"Probe specificity" refers to the characteristics of a probe to describe its ability to distinguish between target and nontarget sequences. In this regard, the fact that the probe is specific means that the nucleotide sequence hybridizes with a given target sequence and is substantially hybridized with the nontarget sequence or with minimal hybridization with the nontarget sequence. Probe specificity depends on sequence and assay conditions.

"Tm" refers to the temperature at which 50% of the probe is converted from the hybridized form to the unhybridized form.

"Standard strain" refers to a strain that is commercially available or readily available.

Sympathy

In order to produce a nucleic acid probe for the detection of bacteria, it is necessary to have specificity only for each bacterium. For this purpose, a specific probe candidate group for each bacterium is selected. The specific probe candidate group sorts and compares the sequences of all possible bacteria in a line through multiple alignments to separately classify specific sequences present only in each of the bacteria to prepare and select a probe candidate group present therein. Probe candidates are determined within the 23S rRNA gene and / or ITS site in each bacterium for bacteria and within the 18S rRNA gene site for fungi. The specificity of the probe candidate group is first confirmed by comparing the similarities between the bacterial strains through BLAST search, and the strains are applied to the hybridization reaction, and the probes that react only with each bacteria are selected for identification in the candidate group. In addition, the nucleic acid probes selected as described above are adapted to clinical trials involving multiple biological samples to confirm their sensitivity.

The nucleic acid probes selected according to the invention are at least 15 oligonucleotides of oligonucleotide and preferably have at least 70%, 80%, 90% or 95% homology with the full complement sequence of the target to be detected. The length of the oligonucleotide of the nucleic acid probe for detecting and identifying each bacterium according to the present invention may be 50 or more. The nucleotides used in the present invention may also be modified nucleotides such as ribonucleotides, deoxyribonucleotides and nucleotides containing inosine or modified groups, but they must not affect hybridization characteristics.

Probe

Nucleic acid probes of the present invention can be used for all known hybridization techniques for testing the presence or absence of a target nucleic acid in a biological sample for diagnostic purposes, such as point deposition on a filter called dot-blot (MANIATIS et al., Molecular Cloning, Cold Spring Harbor, 1982), a DNA transfer technique called Southern blot (SOUTHERN, EM, J. Mol. Biol., 98, 503 (1975)), and an RNA transfer technique called Nothon blot.

In addition, the nucleic acid probes of the present invention can be used in sandwich hybridization systems that enhance the specificity of nucleic acid probe-based assays. The principle and use of sandwich hybridization in nucleic acid probe-based assays is known (DUNN and HASSEL, Cell, 12: 23-36, 1977; and RNAKI et al., Gene, 21: 77-85, 1983). The sandwich hybridization technique employs a capture probe and / or a detection probe, which can hybridize with two different regions of the target nucleic acid and at least one of them (generally the detection probe) has a region of the target specific for the desired bacterium. May hybridize. Capture probes and detection probes should have at least partially different nucleotide sequences. While direct hybridization assays offer advantageous kinetics, sandwich hybridization is advantageous in that it has a high signal-to-noise ratio. In addition, sandwich hybridization can increase the specificity of nucleic acid probe-based assays. Incubation and subsequent washing steps, which constitute the main step of the sandwich hybridization process, are carried out at constant temperature, about 20-65 ° C., respectively. Nucleic acid hybrids are dependent on the number of hybridized bases (the temperature increases in proportion to the size of the hybrid) and also have a dissociation temperature that is dependent on the nature of the hybridized base and the nature of the adjacent base for each hybridized base. It is known. The hybridization temperature used in the sandwich hybridization technique should be selected below the half-dissociation temperature of the hybrid formed between the given probe and the target of the complementary sequence. This semi-dissociation temperature can be determined by simple routine experimentation.

In addition, the nucleic acid probes of the invention can be used in a competitive hybridization protocol. In competitive hybridization, the target molecule competes with hybrid formation between a particular probe and its complement. The more targets are present, the less hybrid is formed between the probe and its complement. Positive signals indicating the presence of a specific target appear to decrease the hybridization response compared to a system without a target added. In certain embodiments, conveniently labeled specific oligonucleotide probes are hybridized with a target molecule. Subsequently, the mixture is placed in a microtiter dish well immobilized with oligonucleotides complementary to the specific probe, allowing the hybridization to continue. After washing, the hybrid between the complementary oligonucleotide and the probe is preferably quantified according to the label used.

In addition, the nucleic acid probes of the present invention can be used for reversed hybridization (Proc. Natl. Acad. Sci. USA, 86: 6230-6234, 1989). In this case, first, the target sequence can be enzymatically amplified by performing PCR using 5 biotinylated primers. The product amplified in the second step is detected by hybridization with specific oligonucleotides immobilized on a solid support. Reverse hybridization can be carried out without amplification. In such cases, the nucleic acid present in the biological sample must be labeled or modified specifically or nonspecifically by chemical or specific dye addition prior to hybridization.

The nucleic acid probe of the present invention can be included in a kit that can be used to quickly determine the presence or absence of a pathogen of interest in the present invention. The kit includes all the components necessary to assay for the presence of the pathogen. In a conventional concept, a kit may contain a stable preparation of a labeled probe, a hybridization solution in anhydrous or liquid form to induce hybridization of a target and probe nucleic acid, a solution for washing and removing unwanted or unhybridized nucleic acid, and a labeled hybrid. Substrates for detection and optionally instruments for detecting labels.

One particular embodiment of the present invention includes a kit that utilizes the concept of a sandwich assay. The kit includes a first element for collecting a sample at a particular site of a patient, such as a sample scraping tool or patter point, a receiving vial, dispersion and lysis buffer. The second element includes an anhydrous or liquid medium for hybridization between the target and the probe nucleic acid and a medium for washing and removing unhybridized and unwanted forms. The third element comprises a solid support on which an unlabeled nucleic acid probe complementary to a portion of the target nucleic acid is immobilized or bound. In the case of analyzing multiple targets, one or more capture probes specific for their respective rRNAs are applied to different individual regions of the dipstick. The fourth element contains a labeled probe that is complementary to a second, different region of the same rRNA backbone where the fixed and unlabeled nucleic acid probe of the third element hybridizes. Here, the nucleic acid probe includes a combination of the probe either in anhydrous form such as lyophilized nucleic acid or in precipitate form such as alcohol precipitated nucleic acid or as a buffer. Any known label labeled may be possible. For example, the probe may be biotinylated by conventional means and the presence of the biotinylated probe may be visualized when the avidin bound to an enzyme such as horseradish peroxidase is added and then reacted with the peroxidase. Detection can be made by contacting with a substrate that can be monitored or monitored using a colorimeter or spectrometer. Such labeling methods and labels of other enzyme forms have the advantage of being economical, highly sensitive and relatively safe compared to radiolabeling methods. The finished product of the assay kit includes various reagents for the detection of labeled probes and those included in other kits, such as instructions, positive and negative controls, and containers for mixing and reacting the various components.

DNA chip

In addition, the nucleic acid probe of the present invention is used as a gene chip. A preferred embodiment of the present invention provides a DNA chip in which the nucleic acid probe of the present invention is immobilized on a solid support. A DNA chip is a high density accumulation of fragments of several nucleotide sequences on a small substrate and is used to detect DNA of an unknown sample by hybridization between DNA immobilized on a substrate and an unknown DNA sample complementary thereto. The substrate on which the probe is to be fixed is made of an inorganic material such as glass or silicon, or a polymer material such as acrylic, polyethylene terephtalate (PET), polystylene, polycarbonate, polypropylene, etc. The surface of the substrate may be flat or have a plurality of holes. The probe is fixed either covalently to the substrate at either 5 'or 3'. The immobilization method is a conventional technique, for example using an electrostatic force or by attaching an amine group on the synthesized oligo to an aldehyde coated slide to induce bonding between the two, or on an amine group coated slide or L-lysine It can be done by integrating on this coated slide or on a slide with a nitrocellulose membrane coated. In one embodiment of the present invention, when the probe is synthesized, a base having an amino residue in the 3 'position is inserted to covalently bond to a glass plate coated with an aldehyde residue.

Fixing and arranging different probes on a substrate surface uses methods such as pin microarrays, inkjets, photolithography, electrical arrays, and the like. In one embodiment of the present invention by using a microarrayer prepared according to a known method in a state in which the probe is dissolved in a buffer solution (Yoon et al, J. Microbiol. Biotechnol., 10 (1), 21- 26, 2000). The principle of microarrays is that the microfabricated pins carry DNA from the plate and transfer it to the same location specified by the computer on the substrate. Between the amine groups on the 3 'position of the probe and the aldehyde groups coated on the glass plate, under conditions where the humidity is maintained between 45% and 65%, preferably between 50% and 55%, for fixing the probe transferred by the microarray. In order to facilitate the reaction, the reaction is induced for at least 1 hour, and left for at least 6 hours to fix the DNA probe.

If necessary to detect cells derived from a living organism or the organism itself, these cells may be partially or completely lysed by chemical and / or physical methods to facilitate access to the RNA and / or DNA of those cells and Contact. The contact can be carried out on a suitable support such as nitrocellulose, cellulose or nylon filters in a liquid medium or solution. Such contact may occur under optimum conditions, suboptimal conditions or limit conditions, which conditions include the temperature, the reactant concentration, the presence of substances that lower the base pair optimal temperature of the nucleic acid (eg formamide, dimethylsulfoxide and urea) and the reaction volume. And / or the presence of a substance (eg, dextran sulfate, polyethyleneglycol or phenol) to reduce and / or accelerate hybrid formation.

Probe production

Nucleic acid probes can be cloned using conventional cloning methods (Maniatis, T., et al. Molecular Cloning: A Laboratory Manual, Cold Spring Harbor, New York, 1982) or chemically using commercially available DNA synthesizers. It can be synthesized and obtained in large quantities.

The probe of the present invention can be produced in single strand or double strand according to a conventional method. As a method of obtaining a single chain probe, the most representative example is a synthesis by a DMT (dimethoxytrityl) off method in an automated synthesizer, subjected to a deprotection reaction, and then a probe composed of a desired number of bases. The probe thus prepared can be attached to a fluorescent substance such as fluorescein isothiocyanate (FITC) at one end of the strand to confirm the presence of a specific nucleic acid. Another method is to make a probe having a nucleotide sequence complementary to the DNA of a Japanese chain, and the primer is hybridized to the DNA of the template, and the Klenow enzyme and the fluorescent substance are attached from the primer. Base (dNTP) is used to synthesize the probe. Since the fluorescent material is attached to the inside of the DNA, it is possible to synthesize a probe having high sensitivity and specificity. As a method of obtaining this heavy strand probe, a genomic DNA or plasmid DNA can be cut with a specific restriction enzyme to obtain a probe containing a gene or base portion of a desired portion. Random priming is a method of hybridizing six random hexamers and template DNA, and then synthesizing probes of various lengths to which fluorescent substances are attached. ³² P at the end of the T4 polynucleotide kinase (polynucleotide kinase) (transfer) can also be synthesized by the fluorescent probe attached, DNA cleavage (DNase) I using a DNA cleavage of the double strands, Using this DNA as a template, a probe can be synthesized using DNA polymerase I and a base (dNTP) to which a fluorescent substance is attached. The double-stranded probe is made into a Japanese chain after denaturation and used for hybridization.

Probes of the invention can be advantageously labeled. Any conventional label can be used. Probes can be labeled using radioactive isotopes such as ³² P, ³⁵ S, ¹²⁵ I, ³ H and ¹⁴ C. Radiolabeling can be carried out according to conventional methods such as end labeling the 3 or 5 position with radiolabeled nucleotides, polynucleotide kinases, terminal transferases or ligases. Another method of radiolabeling is to chemically iodide the probe of the present invention, which results in the binding of several ¹²⁵ I atoms onto the probe. As such, when one of the probes of the present invention is labeled as radioactive, radiation is generally detected using autoradiography, liquid scintillation, gamma coefficients, or other conventional methods. In addition, the probes of the present invention may have residues (eg, antigens or haptens) with immune properties, residues (eg, ligands) with specific affinity for some reagents, residues (eg, enzymes) that provide a detectable enzymatic reaction. , Coenzymes, enzyme substrates or substrates participating in enzymatic reactions) or in combination with residues which provide the physical properties of fluorescence, luminescence or absorption at certain wavelengths. Moreover, the antibody which specifically detects the hybrid formed by a probe and a target can be used. Non-radioactive labels can be provided when chemically synthesizing the probe of the present invention. Adenosine, guanosine, cytidine, thymidine and uracil residues readily bind to other chemical residues and allow detection of hybrids formed between the probe or probe and complementary DNA or RNA fragments.

Target

The nucleic acid is extracted from the sample to provide a nucleic acid substrate for use in detecting and identifying bacteria in the biological sample. Nucleic acids can be extracted from various samples using standard techniques or commercially available kits. For example, kits for separating RNA or DNA from tissue samples may be found in Qiagen, Inc. (California, USA) and Stratagene (California, USA). The QIAAMP Blood Kit allows for the separation of DNA from blood as well as bone marrow, body fluids or cell suspensions. The QIAAMP Tissue Kit allows for the separation of DNA from muscles and organs. As a preferred method of determining whether a biological sample contains rRNA or rDNA indicating the presence of the desired strain, nucleic acid is sonicated from strain cells, for example according to the method described in US Pat. No. 5,374,522 to Murphy et al. Can be released. Other known methods of crushing cells include enzyme use, osmotic shock, chemical treatment, and vortexing with glass beads. Other suitable methods for releasing nucleic acids from strains are described in US Pat. No. 5,837,452 to Clark et al. And US Pat. No. 5,364,763 to Kacian et al. Labeled probes may be added after or concurrent with release of the rRNA in the presence of a hybridization promoter and incubated for the time necessary to reach a significant hybridization reaction at the optimal hybridization temperature.

If the target nucleic acid is double stranded, it is preferable to perform denaturation before performing the detection process. Modification of the double-stranded nucleic acid can be carried out by known methods of chemical, physical or enzymatic modification, in particular by heating to an appropriate temperature, a temperature of at least 80 ℃.

In addition, the target DNA that hybridizes with the probe may be prepared by two kinds of methods. First, a method used in Southern blot or Northern blot, genomic DNA or plasmid DNA is cut with a suitable restriction enzyme and subjected to electrophoresis on an agarose gel to separate DNA fragments by size. The second method is to amplify and use DNA of a desired portion using a PCR method. In this case, using the PCR method, the most common PCR that amplifies the forward and reverse primer pairs using the same amount and the asymmetric addition of the forward and reverse primer pairs of the double strand and the single strand Asymmetric PCR (Asymmetric PCR) to obtain bands at the same time, Multiple amplification method (Multiplex PCR) that can be amplified at the same time by putting several primer pairs, After amplification using four specific primers and Ligase (Ligase) Ligase Chain Reaction (LCR) method to determine the amount of fluorescence by enzyme immunoassay, as well as hot start PCR, nest PCR, modified oligonucleotide primer PCR, reverse transcriptase PCR, semi-quantitative reverse transcriptase PCR, Real time PCR, Rapid Amplification of cDNA Ends (SACE), Competitive PCR, Short tandem repeats; STR), Single Strand Conformation Polymorphism (SSCP), In situ PCR, and DDRT-PCR (Differential Display Reverse Transcriptase PCR).

As a template for the amplification of certain PCR products, relatively homogeneous samples (e.g. blood, bacterial colonies or cerebrospinal fluid) are known to be more suitable than more complex samples (e.g. urine, saliva or excreta) (Shibata in PCR: The Polymerase). Chain Reaction, Mullis et al., Eds., Birkhauser, Boston (1994), pp, 47-54). Samples containing relatively few copies of the target nucleic acid to be amplified, such as cerebrospinal fluid, can be added directly to the PCR. Blood samples should be specially handled during PCR due to the inhibitory properties of red blood cells, and red blood cells should be removed before using blood for PCR. Many methods are used for this purpose, including for example passing through a CHELEX 100 column (BioRad) and the like using the QIAAMP blood kit. Extracting nucleic acids from saliva requires a preliminary purification process that kills or inhibits growth of other bacterial species other than the desired organism. This purification process is accomplished by treating the sample with N-acetyl-L-cysteine and NaOH. This purification process is only necessary when incubating the saliva sample prior to analysis.

In a preferred embodiment of the present invention, a fragment gene is prepared by using DNA of an isolated sample as a template and performing asymmetric amplification (Asymmetric PCR). The fragment gene is obtained by one polymerase chain reaction by differentiating the ratio of forward and reverse primers at 1: 5. In this case, the primers used are part of a nucleotide sequence existing in 16S rRNA to 23S rRNA in common in bacteria (Pirkko K. et al., Clin. Micorbiol., 36 (8), 2205-2209, 1999).

Approximate location maps for these primers are shown in FIG. 1 and F indicates the FITC fluorescent material attached to the 5 'end. In order to identify DNA bound to the probe during PCR, amplification using a 5-FITC attached primer is performed to confirm the binding through fluorescence so that the infection can be identified and the type of infection. In addition, in order to obtain a portion that cannot be amplified by these primers, primers are designed by performing multi-alignment and BLAST by a bioinformatics method.

In the case of fungi, the primers used were part of the nucleotide sequence present in the 18S rRNA of the fungus and designed by the present inventors.

Thereafter, the third denaturation was performed at 94 ° C for 1 minute, hybridization at 54 ° C for 1 minute, extension at 72 ° C for 1 minute, and this was repeated 30 times. Thereafter, the last extension was performed once for 5 minutes at 72 ° C. The product produced by the PCR reaction is confirmed by agarose gel electrophoresis.

Hybridization and Washing

Hybridization techniques are not specific to the present invention. This technique is generally described in Nucleic Acid Hybridization: A Practical Approach, Ed. Hames, BD and Higgins, SJ, IRL Press, 1987; Gall and Pardue (1969), Proc. Natl. Acad. Sci., USA, 63: 378-383, and John, Burnsteil and Jones (1969) Nature, 223: 582-587).

Hybridization conditions are determined by stringency, i.e. the stringency of the operating conditions. The higher the tightening that hybridization takes place, the more specific the hybridization becomes. Constriction is a function of not only the base composition of the probe / target conjugate but also the degree of mismatch between the two nucleic acids. Constriction may also be a function of hybridization reaction variables such as the concentration and type of ions present in the hybridization solution, the nature and concentration of the denaturant and / or the hybridization temperature. The basis of the conditions under which the hybridization reaction should be carried out depends in particular on the probe used. All these data are well known and the appropriate conditions can be determined by routine experimentation in the individual case. Generally, depending on the length of the probe used, the temperature of the hybridization reaction is about 20 ° C. to 65 ° C., in particular 35 ° C. to 65 ° C., in a saline solution at a concentration of about 0.8 to 1 M.

Hybridization between the labeled oligonucleotide probe and the target nucleic acid can be increased using unlabeled helper oligonucleotides following the procedure described in US Pat. No. 5,030,557 to Hogan et al. The helper oligonucleotide binds to a region of the target nucleic acid other than the region bound by the probe. This binding takes on new secondary and tertiary structures in the target region of single-stranded nucleic acids, accelerating the binding speed of the probe.

Those skilled in the art will appreciate that factors affecting the thermal stability of the hybrid formed between the probe and the target may also affect probe specificity. Therefore, the melting point profile, including the melting point temperature of the probe and target hybrid, must be determined empirically for each probe and hybrid of the target. This determination can be made according to the method described in US Pat. No. 5,283,174 to Arnold et al. One method of determining the melting point temperature of the probe and the hybrid of the target involves performing a hybridization protection assay. This assay method forms a hybrid of the probe with the target under conditions of excess target in a lithium succinate buffer solution containing lithium laurylsulfate. A portion of the preformed hybrid is diluted in hybridization buffer and incubated for 5 minutes at various temperatures starting at or below the expected melting point temperature (typically 55 ° C.) and increasing 2 to 5 ° C. The solution is then diluted with weakly alkaline borate buffer and incubated at lower temperature (eg 50 ° C.) for 10 minutes. The acridinium esters linked to single chain probes are hydrolyzed under these conditions while the acridinium esters linked to hybridized probes are relatively protected. This procedure is called hybridization protection assay. The amount of chemiluminescence remaining is proportional to the amount of hybrid and is measured with a luminometer by adding hydrogen peroxide followed by alkali. This data is dipped as a percentage of the maximum signal (usually the lowest temperature) to the temperature. The melting point temperature is defined as the point at which 50% of the maximum signal remains. Alternatively, the melting point temperature for the hybrid of the probe and the target can be determined using a probe labeled with a radioisotope. In all cases, the melting point temperature for a given hybrid may vary by the concentration of salts, detergents and other solutes contained in the hybridization solution. All these factors affect the relative hybrid stability during heat denaturation (Molecular Cloning: A Laboratory Manual Sambrook et al., Eds. Cold Spring Harbor Lab Publ., 9.51 (1989)).

Hybridization conditions can be monitored taking into account several variables, for example, the hybridization temperature, the nature and concentration of the media components, the hybrids formed and the temperature upon washing. Hybridization and washing temperatures are limited to higher values depending on the base sequence, type and length of the probe and the maximum hybridization or washing temperature is about 30 ° C. to 60 ° C. At higher temperatures it competes with hybridization and dissociation or denaturation of the hybrid formed between the probe and the target. Hybridization media are for example about 3xSSC (1xSSC = 0.15 M NaCl, 0.015 M sodium citrate, pH 7.0), about 25 mM phosphate buffer PH 7.1 and 20% deion formamide, 0.02% picol, 0.02% bovine serum albumin, 0.02 % Polyvinylpyrrolidone and about 0.1 mg / ml cut and denatured salmon sperm DNA. The wash medium contains, for example, about 3 × SSC, 25 mM phosphate buffer pH 7.1 and 20% deion formamide. Depending on the modification of the probe and medium, the hybridization or washing temperature should be changed according to known associations to achieve the desired specificity (BD HAMES and SJ HIGGINS, (eds.). Nucleic acid hybridzation.A practical approach, IRL Press, Oxford , UK, 1985). In this regard, since DNA: DNA hybrids are generally less stable than RNA: DNA or RNA: RNA hybrids, hybridization conditions must be appropriately adjusted to achieve specific detection, depending on the nature of the hybrid to be detected.

In a particular preferred embodiment of the invention, hybridization buffer (6 × SSPE (0.15 M NaCl, 5 mM C ₆ H ₅ Na ₃ O ₇ , pH 7.0), 20% (v / v) formamide) is mixed with a PCR amplification gene After dispensing the probe on a fixed glass plate it is reacted for 6 hours at 30 ℃ to induce complementary binding. After the passage of time, wash for 3 minutes in the order of 3 × SPE, 2 × SSPE, 1 × SSPE.

Quantification of the hybrid can be accomplished by labeling the target with fluorescent or radioisotopes, as in the probes described above, according to conventional methods. Labeling may be on the primer itself or by using base residues labeled with fluorescent and radioisotopes for amplification and transcription.

Diagnostic purpose

The probe of the present invention can be precisely diagnosed solely and accurately by infecting diseases caused by each bacterium by detecting the bacterium with high specificity by applying one species to a kit, especially a DNA chip, or by applying two or more probes. By detecting the infectious disease-causing bacteria with a high specificity, it is possible to accurately diagnose the infectious disease caused by these bacteria at the same time. Infectious diseases caused by the bacterium according to the present invention are well known in the literature, for example:

Strains were cultured and chromosomal DNA was extracted using a GIAmp DNA mini kit (QIAGEN, USA). Using the extracted DNA as a template to determine the nucleotide sequence, multiple alignment and BLAST of 16S, ITS, and 23S rDNA sites of each known bacterium were carried out to carry out common common to all known bacteria among the above-mentioned examples. Primer was prepared. Among the prepared common primers, a common primer (1585Fw; 5-TTGTACACACCGCCCGTC) (SEQ ID NO: 406) capable of amplifying the ITS site and 520R, 23S 750F (T), 23S 750F, 970F, and 930R among the common primers of the 23S site , 2960R (T) and 2960RC were prepared by the inventors themselves and the remaining primers were known as the common primers of 23S rDNA (Anthony. RM, et al., J. Clin. Microbiol. 38 (2), 781-788, 2000) Was used to produce. Sequences of the prepared common primers used in sequencing and their approximate positions are shown in Table 2 below.

In order to determine the nucleotide sequence, these common primers were used as a template for chromosomal DNA of the strain, and PCR was performed to purify the product. In order to determine the base sequence of the ITS region and the 23S portion, the 16S rDNA sequence portion which is common to all the known strains by performing multiple alignment and BLAST with 16S rDNA of known bacteria 1585Fw primers were selected and PCR was performed with the 23BR primers. PCR reaction was performed under the following conditions. The first denaturation was performed at 94 ° C. for 7 minutes and the second denaturation at 94 ° C. for 1 minute. Hybridization was performed at 52 ° C. for 1 minute and extension at 72 ° C. for 1 minute, which was repeated 10 times. Thereafter, the third denaturation was performed at 94 ° C. for 1 minute, hybridization at 54 ° C. for 1 minute, and extension at 72 ° C. for 1 minute, which was repeated 20 times. Thereafter, the last extension was performed once at 72 ° C. for 5 minutes. The resulting product was confirmed by agarose gel electrophoresis. The amplified PCR product was purified and sequenced using appropriate primers according to the site of nucleotide sequence to be analyzed by DNA automatic sequencer (Perkin Elmer, ABI prism 3700 sequencer). The primer used in the analysis of the nucleotide sequence was applied to the first prepared common primer, and then the base sequence was analyzed by preparing the 520R, 23S 750F, 23S 750F (T) primer based on the obtained base sequence. PCR was performed with 23BFw and MS38R to determine the next portion of the 23S rDNA sequence.

PCR conditions were performed in the same manner as above, and based on the base sequence obtained therefrom, primers of 970F and 930R were analyzed, and the base sequence was analyzed. In order to determine the nucleotide sequence of the rest of the 23S rDNA, multiple alignment and BLAST with 23S rDNA nucleotide sequence of known bacteria were performed to carry out 2960R which is common to all known bacteria among those exemplified above. (T), 2960RC primers were prepared. PCR with the same conditions as above was carried out with this primer and MS37F, and the base sequence was determined using this primer. The entire nucleotide sequence of 23S rDNA and ITS of each bacterium thus determined is set forth in SEQ ID NOs: 1 to 28.

Example 2

Selection of DNA Probe Candidates to Identify Bacteria

In order to confirm the presence and identification of each bacterium, a probe specific to each bacterium was produced. For the production of specific probes, specificity must be unique to each bacterium. For this purpose, a specific probe candidate group for the bacterium was selected first. Specific probe candidate group is present only in each microorganism by aligning and comparing the sequences of all possible bacteria identified in Example 1 or known in GenBank with the 23S rRNA and ITS nucleotide sequences so far through multiple alignments. Specific base sequences were separately classified to prepare probe candidate groups present therein. Probe candidates were determined within the 23S rRNA gene and / or ITS site for bacteria and 18S rRNA gene site for fungi. The specificity of the probe candidate group was confirmed by comparing the similarity between the fungus by BLAST search. As a result, selected probe candidate groups are listed in Tables 4 to 49 below.

Example 3

Synthesis of Nucleic Acid Probes

Each probe candidate group selected in Example 2 was synthesized for application to a DNA chip. Mononucleotide (Proligo Biochemie GmbH Hamburg Co.) was put into an automated synthesizer (Expedite ^™ 8900, PE Biosystems Co.) and input the sequence and scale of the desired probe to obtain a pure nucleic acid probe of 0.05 umole, respectively. The obtained probe was subjected to electrophoresis to confirm synthesis.

Example 4

Fabrication of DNA Chips

In order to immobilize the DNA probe, a bond between the aldehyde group and the amine group was used. When synthesizing all DNA fragment probes to immobilize the DNA probe, a base having an amino residue was inserted using an aminolinker column (Aminolinker column, Cruachem, Glasgrow, Scotland) in the 3-first position, and a glass plate. Slide glass was coated with an aldehyde residue (CEL Associates, Inc. Huston, Texas, USA).

To fix the probe, use a microarrayer made according to a known technique in a state in which the probe was dissolved in 3X SSC (0.45 M NaCl, 15 mM C ₆ H ₅ Na ₃ O ₇ , pH 7.0) buffer solution. Yoon, SH, et al, J. Microbiol.Biotechnol. 10 (1), 21-26, 2000—the entire contents of this document are incorporated herein by reference), followed by a humidity of about 55%. The DNA probe was immobilized by inducing a chemical reaction for at least 1 hour and leaving it for at least 6 hours under the above conditions. In the bacteria detection probe, the total probe was integrated at a concentration of 100 pmole at intervals of 280 μm in order to prepare a DNA chip fixed with the probe.

In order to confirm that the reaction between the amine group of the probe and the aldehyde on the glass plate was smooth and well immobilized, it was confirmed by staining with SYBRO green II (Molecular Probe, Inc., Leiden, Netherlands).

A fragment gene was prepared by using the DNA of the isolated strain as a template and performing asymmetric amplification (Asymmetric PCR). Fragment gene was obtained by one polymerase chain reaction by differentiating the ratio of forward and reverse primers at 1: 5. In order to identify DNA bound to the probe during PCR, binding was confirmed by fluorescence by amplification using a primer attached with 5-FITC (fluorescein isothiocyanate).

Hybridization and Washing

In order to confirm the specificity and sensitivity of the probe candidate group, the hybridization reaction was performed by applying the PCR product (Example 5) amplified from the cells to a DNA chip (Example 4) to which a nucleic acid probe was immobilized. The nucleic acid probe was tested for cross-reaction (specificity) for the remaining species when a signal appeared after hybridization with a genomic gene isolated from its standard strain.

The DNA plate having the nucleic acid probe immobilized on the glass plate was hydrolyzed by steaming, and then immersed in 70% ethanol to remove the probe that was not immobilized on the glass plate. Subsequently, during the hybridization process, the fluorescent material was attached to an aldehyde residue remaining on the surface of the glass plate, thereby increasing the overall signal and preventing the glass plate from blocking the effect of the specific probe signal (1.3 g NaBH _4). , 375ml PBS, 125ml 100% ethanol) and then reacted for 5 minutes in a shaker (shaker). After washing for 5 minutes with 0.2% SDS, washed 2-3 times with sterile water for 1 minute, and then the water in the glass plate was removed using a centrifuge (1,000rpm, 2 minutes).

To hybridization solution hybridization buffer solution (hybridization buffer: 6 × SSPE; 20XSSPE; 3M NaCl, 0.2M NaH 2 PO 4 · H 2 O, 0.02M EDTA, pH 7.4, 20% (v / v) formamide; Sigma Co , St. Louis) was added to the 30 amplified gene amplified by asymmetric amplification method (Asymmetric PCR) was prepared so that the total volume is 200 μl. The prepared solution was dispensed onto the glass plate on which the probe was immobilized and then covered with a probe-clip press-seal incubation chamber (Sigma Co., St. Louis, Mo.).

To prevent drying around the glass plate during hybridization, a wet tissue was placed in the hybridization chamber and then reacted for 6 hours in a 30 ° C shaking incubator to induce complementary binding. After elapse of time 3 × SSPE (0.45M NaCl, 15 mM C ₆ H ₅ Na ₃ O ₇ , pH 7.0), 2 × SSPE (0.3M NaCl, 10 mM C ₆ H ₅ Na ₃ O ₇ , pH 7.0), 1 After washing for 5 minutes in each of SSPE (0.15 M NaCl, 5 mM C ₆ H ₅ Na ₃ O ₇ , pH 7.0), the water in the glass plate was removed using a centrifuge (1,000 rpm, 2 minutes).
