Chlamydia trachomatis는 인간에게 각종 질병을 일으키는 병원균이며 최근 그 중요성 이 크게 증가하였다. Chlamydia trachomatis감염에 대한 재래식 진단방법은 낮은 정밀도와 낮은 특이성을 갖고 있으며 방법의 수행 자체도 어렵다는 문제점을 지니고 있다. 이들 재래식 진단방법들이 안고 있는 문제점들을 해결하기 위하여 항-병원균 모노클로날 항체를 생산하는 하이브리도마 세포주를 만들 최종목표를 갖고 우선 생쥐에 면역시킬 항원으로 사용할 Chlamydia trachomatis를 동물 숙주 세포내에서 증식시키는데 끼치는 각종 인자들에 대한 영향을 조사연구하였다. 동물 세포 유래의 McCoy 세포내에서 충분한 양의 Chlamydia tracthomatis를 증식시킨 후 불연속 Urografin 구배 원심분리에 의해 정제하였다. Mc-Coy 세포 내에서의 Chlamydia trachomatis의 생성 개체수를 늘리기 위하여 화학제제를 사용했던 바 IUdR 처리가 cycloheximide 처리보다 더 효과적이었으며 Chlamydia trachomatis 증식을 위해 쓸 수 있는 방법이었다. 원심력의 증가가 Chlamydia tracho chomatis의 McCoy 세포 표면에의 흡착을 증진시켰으며 약 3000g 근처에서 최대 감염율을 보였다. 분리 정제한 Chlamydia trachomatis는 SPG 용액 내에서 4$^{\circ}C$에서 48시간 동안 저장될 수 있었으며 더욱 오래 동안 저장시키기 위해서는 -7$0^{\circ}C$까지 냉동시키는 것이 필요하였다.

The present study was performed to identify pathogenic factors of Chlamydia trachomatis, which invade the host cell membrane. We prepared monoclonal antibody against C. trachomatis and searched for pathogenic factors using this antibody, and subsequently identified the surface components of the elementary body of C. trachomatis, i.e., major outer membrane protein (MOMP), lipopolysaccharide (LPS), and two other surface exposure proteins. These proteins are believed to be important in the pathogenesis of host cell chlamydial infection. Additionally, to identify factors related to the host cell and C. trachomatis, we prepared C. trachomatis infected and non-infected McCoy cell extracts, and reacted these with anti-chlamydial LPS monoclonal antibody. We found that anti-chlamydial LPS monoclonal antibody reacted with a 116 kDa proteinaceous McCoy cell membrane component.

Chlamydia trachomatis has now shown that this interesting intracellular parasite is a cause of nongonococcal urethritis, infantile pneumonia, pelvic inflammatory disease and epididymitis, in addition to lymphogranuloma venerum and inclusion conjunctivitis. There are several diagnostic methods for C. trachomatis, but the method using monoclonal antibody is the most sensitive and specific. The hybride cell were prepared by fusion of myeloma cell($P_3X_{63}\;Ag_8{\cdot}V_{653}$) of mouse and lymphocyte of mouse(BALB/c) that were immunized with formalin killed C. trachomatis serotype D. The cell mixtures after fusion were dispensed into 640 wells of the 96 well culture plates and continuously cultured in HAT medium for 2 weeks. The supernatants of culture media in 83(13%) wells were reacted with C. trachomatis, which were determined by enzyme-linked immunosorbent assay in 96 well microplate. The clones that secreted antibody to C. trachomatis were cloned by limiting dilution. Only six monoclones secreted antibody to C. trachomatis. The antibody titer of ascitic fluid that collected from same BALB/c mice bearing hybridoma cells was above 1:100,000. These monoclonal antibodies that were IgG reacted with elementary and reticulate bodies of all serotypes(Ba, D, E, F, G, H, J and LGV type-I) using ELISA and indirect immunofluorescence stain, but there were no cross reaction with other bacteria(coagulase negative Staphylococcus, Proteus and E. coli). We concluded these six monoclones secreted the same monoclonal antibody to C. trachomatis. The sensitivity and specificity of the monoclonal antibody compared with Microtrak(confirmatory test of C. trachomatis, Syva) was 100%, respectively.

Background: Cervical cancer is one of the most common cancers in developing countries and the second most common type of cancer in women globally. Several recent studies suggested a co factor role for Chlamydia trachomatis in pathogenesis of cervical cancer. This study aimed to evaluate existence of C. trachomatis DNA in pathologic blocks of patients with cervical cancer. Materials and methods: Seventy-six formaldehyde fixed paraffin embedded tissue specimens from patients with histologically proven history of cervical cancer as well as 150 blocks from healthy peoples were included in the present study. Thin slices were prepared from selected blocks followed by deparaffinization and DNA extraction; the presence of C. trachomatis DNA was examined by Taq Man real-time PCR. Results: Our TaqMan real time PCR assay with cervical specimens of patients with cervical cancer showed that there was no C. trachomatis DNA. Also, we found three positive specimens among our control group. Conclusion: It seems that based on results obtained from the specimens examined in the present study, there is no association between the presence of C. trachomatis DNA in cervical specimens and cervical cancer.

A total of 339 urethral, vaginal swab and eye discharge materials from the out-patients in the hospitals of Seoul area was microbiologically collected for the detection of Chlamydia trachomatis infection during May through August, 1985. McCoy cell culture system (MCC) and enzyme-likned immunosorbent assay (EIA) methods were employed in this study as the tools for the detection of C. trachomatis, and the detectabilities of two methods were compared. The results obtained in this study are summarized as follows: 1. The positive rate of C. trachomatis in 339 swab specimens was 18.6%, and the rate in females (20.1%) was much higher than that in males (7.1%). 2. The positive rate of C. trachomatis infection the prostitutes was the highest (24.2%), and the rate in the eye discharge specimens obtained from the new barns was 12.8%. 3. The positive rates of C. trachmoatis infection detected in the specimens from the patients with vaginitis and leucorrhea, with infertility, with cystitis and with nongonococcal urethritis were 17.2%, 21.9%. 18.0% and 7.1%, respectively. 4. The positive rate of C. trachomatis infection in 20-25 age group was 30.5%. This rate was the highest among the other age groups. 5. The positive rate of C. trachomatis infection in the randomly screened 89 swab specimens by EIA (30.3%) was much higher than the rate detected by MCC (18.6%). 6. The positive rate of C. trachomatis infection in females detected by EIA was also much higher than in males, and the 20-25 age group showed the highest positive rate as compared to the other age groups. 7. Sensitivity and specificity of EIA for the detection on C. trachomatis were 100% and 88.6%, respectively, in case that MCC was regarded as perfect method. In summarizing the above results, it is known that considerable cases with genital diseases and with eye discharges were associated with C. trachomatis, and that EIA method is recommendable for the detection of C. trachomatis especially in the specimens swabed from the genital tracts.

목 적 : C. trachomatis는 성인의 성 매개성 질환중의 하나로 감염된 산모로부터 수직 전파에 의해 영유아에서 호흡기 감염과 결막염을 일으킨다. 영유아에서 호흡기 감염의 원인으로 C. trachomatis외에도 호흡기 바이러스가 흔한 원인이 되고 있어 최근 영유아에서의 C. trachomatis에 의한 호흡기 감염의 임상양상과 빈도를 알아보고 호흡기 바이러스와의 중복감염에 대해 알아보고자 하였다. 방 법 : 2002년 1월에서 2007년 7월까지 단국대학교병원에 호흡기 감염의 증상으로 입원한 6개월 이하의 환아를 대상으로 하였고 이들에게서 입원 2일 이내 인후 면봉법 혹은 비인두 흡인으로 채취한 객담검체에서 PCR에 의한 Chlamydia PCR 검사를 시행하였다. 또한 Chlamydia 양성인 환아의 $-70^{\circ}C$ 냉동고에 보관되어 있던 비인두 흡인 검체에서 호흡기 바이러스에 대한 multipex PCR 검사를 시행하였다. 의무기록을 후향적으로 검토 분석하였다. 결 과 : 5년 6개월의 연구기간동안 C. trachomatis 항원에 대한 PCR 검사를 시행한 환아 690명으로 그중에서 36명(5.2%)에서 양성을 보였다. Chlamydia 양성인 36명의 환아를 보면 남아가 28명이었고 이들의 평균 나이는 45.4일(12-183일) 이었으며 36명중 30명이 자연분만이었고 제왕절개가 6명 있었다. 36명중 26명에서 호흡기 바이러스를 검사를 시행하였으며 이중 12명에서 호흡기 바이러스가 검출되었다. 검출된 호흡기 바이러스의 종류를 보면 RSV 6명, RV 2명, 그 외 IFV A, PIV 3, AdV, CoV OC43, HMPV가 각각 한명에서 검출되었다. Chlamydia PCR 양성인 환아의 임상양상을 보면 기침, 수포음, 흉부견축, 빈호흡을 보였고 7%에서 발열 증상이 있었다. 호흡기 바이러스와 중복감염이 있는 12명의 환아와 비교한 결과 발열과 수포음이 의미있는 차이를 보였으며 혈액 검사상 호흡기 바이러스 중복감염이 있는 환아에서 CRP의 증가로 의미있는 차이를 보였다. 결 론 : C. trachomatis에 의한 호흡기 감염은 자연분만이 아닌 환아에서도, 또한 생후 6개월인 환아에서도 감염을 보였으며 46%에서 호흡기 바이러스와 중복감염을 보였다. 호흡기 바이러스와 중복감염이 있는 경우 RSV가 가장 많은 빈도를 보였다. C. trachomatis에 의한 호흡기 감염에서 발열을 동반하거나 CRP가 높은 경우 호흡기 바이러스와의 중복감염을 의심할 수 있다. 생후 6개월 이하의 환아에서 호흡기 감염의 원인으로 C. trachomatis의 감염을 고려해야 하며 호흡기 바이러스와의 중복감염에 대한 지속적인 연구가 필요하다고 생각된다.

Cervical cancer continues to be an important public health problem in Thailand. While the high risk human papillomavirus (HPV) types have been established as the principle causative agent of both malignancies and the precursor lesions, cervical intraepithelial neoplasia (CIN), other factors may also be involved like other sexually transmitted diseases, as well as smoking. Chlamydia trachomatis is an obligate intracellular Gramnegative bacterium which has a tendency to cause chronic infection featuring inflammation and therefore might be expected to increase the risk of cervical cancer. In the present nested case-control study, 61 cases of cervical cancer and 288 matched controls with original serum samples were identified from the Khon Kaen Cohort, established in the North-East of Thailand, by linkage to the Khon Kaen population based cancer registry. C. trachomatis specific IgG antibodies at recruitment were measured by microimmunofluorescence and assessed for association with cervical cancer using STATA release10. No significant link was noted either with all cancers or after removal of adenocarcinomas. The results suggest no association between Chlamydia infection and cervical cancer development in North-East Thailand, but possible influencing factors must be considered in any future research on this topic.

Fitz-Hugh-Curtis 증후군은 골반 내 염증성 질환을 가진 환자의 직접적 간 실질 침범이 없는 간피막 염증에 의한 간주위염으로, 1930년대에 Thomas Fitz-Hugh와 Arthur Curtis에 의해 보고되었다. Neisseria gonorrhea나 Chlamydia trachomatis에 의해 발병하며, 항생제로 치료되는 양성 성교전파질환이다. 대부분 가임기의 젊은 여성에서 발견되지만, 15세의 청소년에서 진단된 증례가 있어 보고하는 바이다. 15세 여자 환자가 1개월 전부터 발생한 간헐적인 우상복부와 하복부의 통증을 주소로 내원하였다. 환자는 한 달 전 남자친구와 첫 성교를 한 이후, 5일 전까지 10여 차례정도 성교를 하였다. 사회력 상 고등학교 1학년 생이고, 월경 주기는 28-30일로 규칙적이었다. 내원 당일 시행한 임신 반응 검사는 음성이었다. 시행한 복부전산화단층촬영에서 우측 간엽의 가쪽 부분이 동맥기 조영증강을 보이며 골반내감염을 동반하고 있었다. 부인과 검진 상 질경부 면봉 검사에서 Chlamydia trachomatis 양성소견을 보였으며, 소변배양검사에서 Neisseria gonorrhea가 동정되었다. Fitz-Hugh-Curtis 증후군 진단 하에 4주간 doxycycline과 metronidazole의 경구용 항생제 복용 후 호전되었다.
