Backgrounds: Trichomoniasis is one of the most common sexually transmitted infections in the world. The main aim of the present descriptive study was to determine the prevalence rate and clinical symptoms of trichomoniasis among women referring to the hospital in Mahshahr city in Khuzestan province, southwest of Iran. Materials & Methods: Urine samples were collected from ۲۲۰۰ women referring to Imam Musa Kazim hospital in Mahshahr city. In addition, ۵۰۰ Pap smear samples were used for early detection of Trichomonas vaginalis. At first, parasitological tests were performed to detect T. vaginalis in urine and dissolved Pap smear samples using microscopic examination. Finally, DNA extraction was performed on ۳۴ parasites isolated from positive urine and Pap smear samples. Then the ۱۸s rRNA gene of the parasite was amplified by PCR method. The PCR products of the ۱۸s rRNA gene were finally sequenced. Findings: The prevalence rate of this parasite was determined to be ۱.۵۴%. The highest prevalence rate of infection and clinical symptoms were observed in women aged ۳۱-۴۰ years. Totally, clinical symptoms were observed in ۶۴.۷۰% of infected women, including vaginal itching and irritation (۶۴.۷۰%) and abnormal discharge (۲۶.۴۷%). Conclusion: The prevalence rate of Trichomonas infection was relatively low in women living in Mahshahr. In addition, about ۳۵.۲۹% of infected women were found to be clinically asymptomatic.
