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...

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,...

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...

background : as prenatal screening for sexually transmitted infections and treatment of infected pregnant women is not routinely performed in iran and prevalence of two sexually transmitted pathogens, chlamydia trachomatis and mycoplasma genitalium , in sabzevar (east of iran) is unknown, we decided to perform this prospective study. methods : one hundred ninety-six urine specimens of pregnant ...

Worldwide Chlamydia trachomatis and Neisseria gonorrhoeae are two of the most prevalent sexually transmitted pathogens. The present study aimed to estimate the prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae infection in women from Taif, western region, KSA. A polymerase chain reaction (PCR) method was carried using DNA extracted from 144 female urine samples. Primer pairs specifi...

Synovial fluid cells from 12 patients with reactive arthritis (ReA) triggered by Chlamydia trachomatis were studied for the presence of Chlamydia DNA using the ligase chain reaction (LCR) LCx (Abbott) and the polymerase chain reaction (PCR) Amplicor (Roche). In addition, peripheral blood leucocytes from 11 of these patients were analysed by LCR. As controls, seven patients with newly diagnosed ...

BACKGROUND Chlamydia trachomatis is a ubiquitous pathogen worldwide and causes ocular. urogenital, and respiratory infections in humans. C. trachomatis infection of lower genital tract is one of the most prevalent sexually transmitted diseases (STDs) in different parts of the world. Their treatment, follow-up, and hopefulness for future is very important. Objectives of this study were to see th...
