Anatomical site prevalence and genotypes of Chlamydia trachomatis infections among men who have sex with men: a multi-site study in China.

ABSTRACT: BACKGROUND:Chlamydia trachomatis (CT) infection is one of the most pervasive sexually transmitted infections and has high prevalence in urogenital and extra-urogenital sites among men who have sex with men (MSM). This study investigated anatomical site-specific prevalence and genotypes of CT among MSM recruited from three geographic areas in China. METHODS:We collected urine specimens and anorectal, pharyngeal swab specimens from 379 MSM. CT infection was identified using polymerase chain reaction and CT genotyping was determined by sequences of the ompA gene. RESULTS:The results indicated that the overall prevalence of CT infection was 18.2% (95% confidence intervals [CIs], 13.9-22.5%) and significantly different between the cities (p = 0.048). The infection was most common at the anorect
