Chlamydiae are obligate intracellular bacterial pathogens that exhibit a broad range of host tropism. Differences in host tropism between Chlamydia species have been linked to host variations in IFN-gamma-mediated immune responses. In mouse cells, IFN-gamma can effectively restrict growth of the human pathogen Chlamydia trachomatis but fails to control growth of the closely related mouse pathog...

Infection with the bacterium Chlamydia trachomatis can lead to a variety of diseases, including ectopic pregnancy, infertility and blindness. Exposure of the host to C. trachomatis stimulates multiple innate and adaptive immune effectors that can contribute towards controlling bacterial replication. However, these effectors are often insufficient to resolve the infection and prevent re-infectio...

This study was conducted to determine the prevalence and distribution of urogenital Chlamydia trachomatis genotypes in symptomatic male patients who were referred to the clinics of the Istanbul Faculty of Medicine. Of 419 urogenital swabs, 57 samples (13.6 %) were positive for C. trachomatis. Genotype distribution of C. trachomatis-positive samples identified five genetic variants namely genoty...

Chlamydia trachomatis is a sexually transmitted disease (STD) commonly diagnosed in pregnancy. C. trachomatis has been linked to several pregnancy complications including premature rupture of membranes (PROM), preterm labor and birth, low birth weight, intrauterine growth retardation, and postpartum endometritis. Infants born to mothers through an infected birth canal are at risk for acquiring ...

Chlamydia trachomatis is an important cause of postpartum endometritis and neonatal conjunctivitis. However, the prevalence of chlamydial genital infection varies considerably from one population group to another. A study was thus conducted to determine the incidence of C trachomatis infection of the cervix in an unselected group of women attending a Belfast antenatal clinic. One hundred and si...

In a study to evaluate the possible role of Chlamydia trachomatis and Neisseria gonorrhoeae in acute salpingitis, 26% of 106 patients with severe symptoms had positive culture results for C. trachomatis; 43% of the 72 patients from whom paired sera were obtained had either positive culture results for or seroconversion in the single antigen immunofluorescence test to C. trachomatis. Twenty-six ...

Chlamydia trachomatis is a Gram-negative obligate intracellular bacterial pathogen. It is the leading cause of bacterial sexually transmitted disease in the world, with more than 100 million new cases of genital tract infections with C. trachomatis occurring each year. Animal models are indispensable for the study of C. trachomatis infections and the development and evaluation of candidate vacc...

Since genital infection with Chlamydia trachomatis may be associated with cervical abnormalities 160 patients with grandular ectopia attending a gynaecological outpatient clinic were examined for antibodies against C trachomatis, the presence of C trachomatis infection, and cytological and histopathological abnormalities of the cervix.A significantly higher incidence of histological dysplasia w...

The Chlamydia trachomatis plasmid is a virulence factor. Plasmid copy number, C. trachomatis load and disease severity were assessed in a treatment-naive population where trachoma is hyperendemic. By using droplet digital PCR, plasmid copy number was found to be stable (median, 5.34 [range, 1 to 18]) and there were no associations with C. trachomatis load or disease severity.

OBJECTIVES Sampling of both the cervix and urine increases the chance of detection of Chlamydia trachomatis compared with sampling either site alone. We determined the effect of combining urine and cervical swab specimens in the clinic setting on the sensitivity of C trachomatis polymerase chain reaction (PCR) testing. METHODS For each of 100 women attending a genitourinary medicine clinic wi...
