چکیده
It has been approved that the infection caused by Chlamydia trachomatis (C. trachomatis) is one of the major causes of infertility and adverse birth outcomes in populations. The C. trachomatis epidemiology among childbearing-age women in Iraq has not been recognized yet. This study aimed to detect the prevalence of C. trachomatis infection among pregnant and non-pregnant women using the polymerase chain reaction (PCR) assay and phylogenetic analysis of local isolates. In total, 200 endocervical swabs were collected from adult married pregnant (n=100) and non-pregnant women (n=100) from June to July 2021. Targeting the omp1 gene, 9% of the total samples were positive for C. trachomatis, and significant increases were reported among non-pregnant compared to pregnant women. The PCR products of five positive local isolates were selected randomly, sequenced, and documented in the National Centre for Biotechnology Information (NCBI) with the accession numbers OK094104.1, OK094105.1, OK094106.1, OK094107.1, and OK094108.1. Analysis of the homology sequence of the local and NCBI-BLAST isolates revealed a significant association with the Russian (MF288585.1) isolate. Statistical analysis of reproductive data revealed a higher prevalence, odds ratio (OD), and risk in asymptomatic, compared to symptomatic cases. Although no significant variation was detected in prevalence rate among single and multiple symptomatic women, increases were observed in OD values and risk of multiple symptomatic women. Reportedly, chronic pelvic pain was more prevalent than pelvic inflammatory diseases, ectopic pregnancy, and infertility in single symptomatic women. Regarding the demographic characteristics (i.e., age, the place of residence, and occupation), prevalence and risk of infection were higher in women who were <30 years, lived in urban areas, and had a job, compared to women who were ≥30 years, lived in suburban and rural areas, and had a free job. In conclusion, the course of chlamydial infections is usually unpredictable, diverse, and asymptomatic and has remained almost unrecognized. Therefore, PCR-based methods can apply successfully to detect C. trachomatis in both pregnant and non-pregnant women.
