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.
