background: sexually transmitted infections (stis) are among the most common causes of illness in the world and have far-reaching health, economic and social consequences for many countries. failure to diagnose and treat stis at an early stage may result in serious complications and sequels. objective: this study aimed to determine the prevalence of chlamydia trachomatis infection in patients w...

background: although a simple and direct method does not exist for the detection of chlamydial infections, there are situations in which reliable serological tests, with sensi-tivity related to a specific antigen, could be helpful. objective: the aim of this study was to clone the first 1100 bp of the c. trachomatis outer membrane protein 2 (omp2) gene in order to prepare a recombinant protein ...

an amplification polymerase chain reaction (pcr) test for the direct detection of chlamydia trachomatis in urethral and endocervical swab specimens from symptomatic and asymptomatic women and men were compared to standard culture technique. during 6 months, 300 endocervical swab specimens from 205 asymptomatic women (64.4%) and 95 symptomatic women (31.6%), and 187 urethral swab specimens from ...

background: chlamydia trachomatis is the most reported bacterial sexually transmitted disease, especially among young women worldwide. aim of this study was comparison to evaluate the prevalence of chlamydia trachomatis infection in woman with tubal infertility by means of pcr and cell culture techniques. methods: fifty-one women with confirmed tfi were enrolled in this study in (avicenna infer...

Chlamydiae are intracellular, gram-negative, and prokaryotic microorganisms. Capable of causing disease in many mammalian avian species, there three types that cause humans: Chlamydia trachomatis, pneumoniae, psittaci. Among the chlamydia C. trachomatis is most studied encountered type because it a leading trachoma sexually transmitted diseases. known pathogen genital tract, can also be routine...

The aims of this study were to compare a novel PCR-based Chlamydia trachomatis detection and genotyping (Ct-DT) assay with the FDA-approved, commercially available C. trachomatis detection Hybrid Capture 2 (HC2) assay and to investigate the C. trachomatis serovar distribution among young women in a rural Costa Rican study population. A total of 5,828 sexually active women participating in a com...

Taxonomy The order chlamydiales has one family, chlamydiaceae, and one genus, chlamydia. Currently four species are recognized, Chlamydia trachomatis, Chlamydia pneumoniae, Chlamydia psittaci , and Chlamydia pecorum. To date, 19 different Chlamydia trachomatis serovars (41) and several Chlamydia psittaci serovars are known (6 avian (65), 9 mammalian (29)), but only one Chlamydia pneumoniae (40,...

Abstract Background The LabGenius C-CT/NG-BMX assay (LabGenius CT/NG; BIOMEDUX, Gyeonggi-do, Republic of Korea) is a recently developed real-time polymerase chain reaction that can simultaneously detect sexual transmitted pathogens (Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG)) in vaginal swab specimen or urine specimen. Methods To evaluate the analytical performance, total 343 167...

OBJECTIVES Using polymerase chain reactions, this study aimed to evaluate the incidence of neonatal chlamydial conjunctivitis in our region of Hong Kong and explore any association between such conjunctivitis and nasopharyngeal colonisation with Chlamydia trachomatis. DESIGN Prospective epidemiological study. SETTING Regional hospital, Hong Kong. PATIENTS Consecutive patients with neonata...

BACKGROUND The WHO seeks to control trachoma as a public health problem in endemic areas. Achham District in western Nepal was found to have TF (trachoma follicular) above 20% in a 2006 government survey, triggering 3 annual mass drug administrations finishing in 2010. Here we assess the level of control that has been achieved using surveillance for clinical disease, ocular chlamydia trachomati...
