Methods BALB/c mice were immunized with SDS-PAGE purified major outer membrane protein (MOMP) from CT and the monoclonal antibodies were obtained subsequently. Two-site ELISA was developed to detect CT infection. Results: The established assay was able to detect as low as 1.248ug/ml MOMP with interrun and inrun CV 6.9% and 3.1% respectively. 94% (34/36) of culture-positive samples were found to be positive in the current examination, indicating the high sensitivity of this assay. Conclusion: The assay is applicable for clinical diagnosis of CT infection.展开更多

Objectives: To find out the level and functions of Chlamydia trachomatis heat shock protein (C-hsp60) antibody, anti-spermantibody(ASAb), interleukin 1(IL-1), interleukin 6 (IL-6),interleukin 8 (IL-8), Tumor necrosis ...Objectives: To find out the level and functions of Chlamydia trachomatis heat shock protein (C-hsp60) antibody, anti-spermantibody(ASAb), interleukin 1(IL-1), interleukin 6 (IL-6),interleukin 8 (IL-8), Tumor necrosis factor alpha (TNF-α)and γ-interferon (IFN-γ) in patients with CT-related infertility. Methods: CT-DNA of cervical secretions was detectedthrough polymerase chain reaction (PCR) and migrationinhibiting factor (MIF) was employed to measure IgG titre ofCT MOMP antibody. Western blot was used to determinepresence of C-hsp60 antibody and enzyme-linkedimmunoadsorbent assay (ELISA) measured ASAb of IgG typein blood serum and determine the content of IL-1, IL-6. IL-8.TNF-α. IFN-γ in uterine tube fluid. Results: 68 patients had positive CT-DNA, among which 57(83.8%) had C-hsp60 antibody. Among the 172 patients withnegative CT-DNA, 64 patients (37.2%) also had C-hsp60Antibody. There was a significant difference (P<0.01) betweeninfertile patients and control group patients in the presence ofAAb. Infertile patients with positive CT-DNA had higher levels of IL-1、IL-6. IL-8. TNF-α. IFN-γ in uterine tube fluidcompared to control group patients (P<0.01). Conclusion: Firstly, those patients with negative CT testingfrom cervical secretions cannot be ruled out for CT infectionin deep parts of the body (such as oviduct, pelvic kidney).Detection of C-hsp60 Antibody may help to diagnose suchcases of CT. Secondly, CT infection of the oviduct can raiselevels of IL-1、IL-6、 IL-8、 TNF-α. IFN-γ. The pathogenesis ofinfertility caused by CT infection in the reproductive tractmay be related to cytokine production and inflammatoryresponses mediated by C-hsp60 Antibody, IL-1, IL-6, IL-8,TNF-α, and IFN-γ.展开更多
