| Popis: | Background and Objectives: Chlamydia trachomatis is an obligate intracellular pathogen. Infection with C. trachomatis in pregnant women can result in maternal and fetal death, due to pelvic inflammatory disease. Therefore, we aimed to evaluate this infection in pregnant women and identify circulating genotypes of C. trachomatis in Tehran, Iran. Materials and Methods: Endocervical swabs were obtained from 101 pregnant women and tested by PCR assay to detect cryptic plasmid gene. Positive isolates were analyzed for C. trachomatis genotypes through amplification and sequencing of the omp1 gene and alignment with deposited sequences in Gene Bank. Results: Infection with C. trachomatis was observed in 11 cases, yielding an overall prevalence of 10.8% in total. The majority of infected women were asymptomatic and the rate of infection was found more in women at the age of ≥30 years. However, no statistical association was found between C. trachomatis infection and risk factors in pregnant women. Analysis of isolated sequences revealed genotypes E (44.4%), D and F (both 22.2%), and K (11.2%) as main genotypes of C. trachomatis in this region. Conclusion: Results of this study showed the prevalence of C. trachomatis infections among pregnant women is relatively high. Identifying the precise rate of infection and associated genotypes in other regions is suggested. |
