Multivariate logistic regression analyses (covariates include contraception, gravidity (\u22651), abnormal vaginal discharge, adverse pregnancy outcomes, reproductive tract symptoms and abnormal cervical cytology) were performed to evaluate the associations between <jats:italic>Chlamydia trachomatis<\/jats:italic> genotypes and cervical intraepithelial lesions and genital clinical symptoms.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among 375 <jats:italic>Chlamydia trachomatis<\/jats:italic> positive cervical swabs, the prevalence of coinfection with <jats:italic>Neisseria gonorrhoeae, Candida albicans, Trichomonas vaginitis, Vulvovaginal candidiasis<\/jats:italic>, and HPV were 0.8%, 2.7%, 2.4%, 10.1% and 15.5%, respectively. 306 were genotyped successfully, and nine genotypes were identified.
