Description

Sexually Transmitted Disease-Inducible Microorganisms}

The present invention relates to a method for simultaneously detecting a variety of microorganisms causing adult disease, and to a diagnostic kit for adult disease using the same.

Sexually transmitted diseases (STDs), also known as sexually transmitted infections (STIs) or venereal disease (VD), are due to human sexual activity such as sexual intercourse, oral sex and anal sex. Includes the spread of disease throughout. STD is mainly caused by causative agents of (a) sex-borne diseases, (b) vaginitis, (c) genital ulcers, and (d) nongonorrheal urethritis (NGU). In the past, adult disease was mostly regarded as STD or VD, but has recently been referred to as STI, which encompasses that anyone can be infected and potentially infect others without a sign of a particular disease. In addition, some STDs can be delivered via needles used by infected persons, as well as through childbirth or breastfeeding. In general, adult diseases are caused by bacteria, fungi, viruses, parasites or protists.

Non-gonococcal urethritis is but urethritis occurs in men Neisseria Kono Leah (Neisseria gonorrhoeae, Neisseria gonorrhoeae) represents the you do not see the disease, the most common cause of non-gonococcal urethritis is Chlamydia trachomatis (Chlamydia trachomatis), that besides urea plasma Yu reahra Iticum ( Ureaplasma urealyticum ) and Mycoplasma genitalium are also known as important causative organisms. All of these bacteria are common causes of anterior urethritis in men, can combine epididymitis and prostatitis, and become an important cause of infertility. It is also a major cause of cervicitis and pelvic inflammatory diseases in women, and can cause infertility and ectopic pregnancy by causing fallopian tube occlusion.

In the United States, chlamydial infection is the most common today, and in Korea, gonorrhea has recently decreased, but chlamydial infection and non-germ urethritis have increased.

Unlike other diseases, STD is latent asymptomatic and often worsens, and re-infection is easy. Therefore, it is important to develop a method for early detection of asymptomatic carriers of STD to effectively diagnose asymptomatic carriers. If urethritis is found in a patient, it must first be distinguished whether it is gonococcal or non-gonococcal because of different treatment methods and procedures. However, in recent years, there is a tendency that the distinction between the two due to the misuse of the antimicrobial agent and the increase of mixed infection tend to be ambiguous, and more efficient molecular genetic testing is required for accurate diagnosis.

For example, the diagnosis of Neisseria gonorrea that causes gonococcal urethritis primarily uses the Gram staining method. Depending on the Gram staining method, the presence of characteristic intracellular Gram-negative bacteria is a convenient and relatively accurate method of widespread use.However, in asymptomatic or minimally symptomatic gonococcal urethritis, the Gram staining may be ambiguous or false negative ( There are many drawbacks to false negatives. In addition, there are gonococcal culture methods for supplementing gonococcal culture gram staining method, but very useful and accurate test method has a disadvantage in that a lot of time and cost to know the test results. In addition, enzyme immunoassay (EIA) and immunofluorescence techniques have been used as new antigen identification methods for diagnosing Neisseria gonorrea-infected diseases, which are faster and more sensitive than culture tests. sensitivity and specificity, but with the disadvantage of high cost.

Non gonococcal urethritis has recently been increasing incidence in contrast to the reduction of gonococcal urethritis. Non gonococcal urethritis is not a single disease, but a type of syndrome that can be caused by a variety of microorganisms. Chlamydia trachomatis is the most important causative agent of non gonococcal urethritis. Chlamydia trachomatis is a microorganism that has a life cycle of intracellular parasitism. It contains both DNA and RNA in the genome, and there are 15 serotypes. to be. Human diseases that can be caused by this are STD including trachoma and respiratory infections, urethritis and cervicitis, epididymitis, pelvic inflammatory disease. Recently, it has been reported that chlamydia causes myocarditis.

Conventional methods for identifying Chlamydia trachomatis include (a) a method for confirming a specimen collected at an infected site through culture / separation; (b) a method of directly smearing and staining epithelial cells of the infected area to identify bacteria; (c) separating and identifying the antibody in the serum of the patient; And (d) a method using molecular genetic techniques such as polymerase chain reaction (PCR) and hybridization, but the method of (a) has a disadvantage in that it takes a long time and has low diagnostic sensitivity. The method of (b) is simple but also has low diagnostic sensitivity. In addition, the method of (c) has a relatively high sensitivity but has the disadvantage of high cost and dedicated equipment. Therefore, PCR-based molecular genetic methods are the main trend to be used.

PCR-based molecular genetic methods analyze the genotype of the bacterial genome, ie, the sequences of DNA and RNA. For example, diagnostic kits that only test for Neisseria gonorrea infection or chlamydia infection are already commercially available. Ultimately, the method of testing must be easy and simple, not only to obtain accurate results quickly, but also to simultaneously test multiple microorganisms in order to be cheap. Therefore, there is an urgent need in the art for the development of multiplex PCR technology capable of simultaneously analyzing several STD-causing bacteria and further knowing information such as antimicrobial resistance.

As used herein, the term " primer " means an oligonucleotide in which the synthesis of a primer extension product complementary to a nucleic acid chain (template) is induced, that is, the presence of a polymerizing agent such as a nucleotide and a DNA polymerase, It can act as a starting point for synthesis at suitable temperature and pH conditions. Preferably, the primer is a deoxyribonucleotide and is a single strand. The primers used in the present invention may include naturally occurring dNMPs (i.e., dAMP, dGMP, dCMP and dTMP), modified nucleotides or non-natural nucleotides. In addition, the primers may also include ribonucleotides.

The primer should be long enough to be able to prime the synthesis of the extension product in the presence of the polymerizing agent. The appropriate length of the primer is determined by a number of factors, such as temperature, application, and the source of the primer. The term " annealing " or " priming " means that the oligodeoxynucleotide or nucleic acid is apposited to the template nucleic acid, which polymerizes the nucleotide to form a complementary nucleic acid molecule to the template nucleic acid or a portion thereof .

PCR is the most well-known nucleic acid amplification method, and many variations and applications thereof have been developed. For example, touchdown PCR, hot start PCR, nested PCR and booster PCR have been developed by modifying traditional PCR procedures to enhance the specificity or sensitivity of PCR. In addition, multiplex PCR, real-time PCR, differential display PCR (DD-PCR), rapid amplification of cDNA ends (RACE), inverse polymerase chain reaction (inverse polymerase) chain reaction (IPCR), vectorette PCR and thermal asymmetric interlaced PCR (TAIL-PCR) have been developed for specific applications. For more information on PCR, see McPherson, MJ, and Moller, SG PCR . BIOS Scientific Publishers, Springer-Verlag New York Berlin, Heidelberg, NY (2000), the teachings of which are incorporated herein by reference.

When the method of the present invention is carried out using a primer, a gene amplification reaction can be performed to detect a target gene in an analyte (eg, a sample containing various microorganisms). Therefore, the present invention performs a gene amplification reaction using a primer that binds to cDNA synthesized from mRNA in the sample.

To obtain mRNA, total RNA is isolated from the sample. Isolation of total RNA can be carried out according to conventional methods known in the art. See Sambrook, J. et al. , Molecular Cloning. A Laboratory Manual , 3rd ed. Cold Spring Harbor Press (2001); Tesniere. , C. et al. , Plant Mol. Biol. Rep. , 9: 242 (1991); Ausubel, FM et al. , Current Protocols in Molecular Biology , John Willey & Sons (1987); and Chomczynski, P. et al. ., Anal Biochem 162:.. 156 (1987)). For example, Trizol can be used to easily isolate total RNA in cells. Next, cDNA is synthesized from the separated mRNA, and this cDNA is amplified. When the total RNA of the present invention is isolated from human samples, it has a poly-A tail at the end of the mRNA, and cDNA can be easily synthesized using oligo dT primer and reverse transcriptase using this sequence characteristic ( PNAS USA , 85: 8998 (1988); Libert F, et al. , Science , 244: 569 (1989); and Sambrook, J. et al. , Molecular Cloning.A Laboratory Manual , 3rd ed.Cold Spring Harbor Press (2001). Next, the synthesized cDNA is amplified through gene amplification reaction.

The primer used in the present invention is hybridized or annealed at one site of the template to form a double-stranded structure. Conditions suitable nucleic acid hybridization to form such double-stranded structure is Joseph Sambrook, such as, Molecular Cloning, A Laboratory Manual, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY (2001) and Haymes, BD, etc., Nucleic Acid Hybridization , A Practical Approach , IRL Press, Washington, DC (1985).

Various DNA polymerases can be used for amplification of the present invention and include “Clenow” fragments of E. coli DNA polymerase I, thermostable DNA polymerase and bacteriophage T7 DNA polymerase. Preferably, the polymerase is a thermostable DNA polymerase obtainable from a variety of bacterial species, including Thermus aquaticus (Taq), Thermus thermophilus (Tth), Thermus filiformis , Thermis flavus , Thermococcus literalis , and Pyrococcus furiosus (Pfu) .

When performing the polymerization reaction, it is preferable to provide the reaction vessel with an excessive amount of the components necessary for the reaction. The excess amount of the components required for the amplification reaction means an amount such that the amplification reaction is not substantially restricted to the concentration of the component. It is desirable to provide the reaction mixture with such joins as Mg ²⁺ , dATP, dCTP, dGTP and dTTP to such an extent that the desired degree of amplification can be achieved. All enzymes used in the amplification reaction may be active under the same reaction conditions. In fact, buffers make all enzymes close to optimal reaction conditions. Thus, the amplification process of the present invention can be carried out in a single reaction without changing conditions such as the addition of reactants.

In the present invention, annealing is carried out under stringent conditions that allow specific binding between the target nucleotide sequence and the primer. The stringent conditions for annealing are sequence-dependent and vary with environmental variables. This amplified target gene is analyzed by a suitable method to detect adult disease-causing microorganisms. For example, the target gene can be detected by performing gel electrophoresis on the result of amplification reaction described above, and observing and analyzing the band formed as a result.

The term " hybridization "as used herein means that two single-stranded nucleic acids form a duplex structure by pairing complementary base sequences. Hybridization refers to the complementarity between single- The degree of complementarity required for the hybridization can vary depending on the hybridization reaction conditions and can be controlled, inter alia, by temperature. The term " mismatch " Annealing " and " hybridization " are not different, and are used in this specification.
