Resumen:
OBJECTIVE: Chlamydia trachomatis is the most prevalent bacteria causing sexually transmitted infections. In women, this infection can cause cervicitis and urethritis, although it's usually asymptomatic. The aim of this study was to investigate the prevalence of C. trachomatis in women attending the lab Instituto de Previsión Social and detect the genotypes. METHODS: Endocervical samples from 505 symptomatic and asymptomatic women were assayed. It was determined the presence of C. trachomatis by PCR through amplification of a fragment of the cryptic plasmid. Positive samples were genotyped by the partial amplification of the ompA gene and analyzed phylogenetically. RESULTS: Forty-three positive samples were detected to infection with C. trachomatis, obtaining a prevalence of 8.5% (IC 95%: 6.4-11.3%). The prevalence of C. trachomatis was higher in women with vaginal symptoms [11.3% (30/265) vs. 5.4% (13/240)] (p = 0.018), as well as in women under 26 year-old [11.5% (28/244) vs. 6.2% (15/246)] (p = 0.021). Based on phylogenetic analysis, it was observed that 62% of the samples were genotype E, 15% genotype J, 15% genotype D, and 8% genotype F. CONCLUSIONS: This work is the first contribution on the molecular epidemiology of C. trachomatis in the Misiones province, Argentina, which shows the rate of prevalence of this bacterium and offers information on circulating genotypes.
