Detection of Trichomonas vaginalis by microscopy and molecular methods in women referred to health centers in Tabriz, Northwest Iran.

ABSTRACT

Trichomoniasis is a parasitic disease that affects the human reproductive and urinary systems, representing a substantial non-viral sexually transmitted infection worldwide. Given its impact on reproductive health, and the limited available information on the prevalence of Trichomonas vaginalis, this study aimed to evaluate the prevalence of T. vaginalis among women referred to health centers in Tabriz, Northwest Iran. Study was conducted on 448 suspicious women who attended to 29Bahman hospital in Tabriz, Northwest Iran, during September 2020 to September 2021. Demographic data were collected according to the study protocol. Vaginal discharges were obtained using sterile swabs, and the prevalence of T. vaginalis was determined using Papanicolauo staining and PCR method. Among the 448 cases studied, 48 (10.7%) samples were suspected as a T. vaginalis infection, while 4 (0.89%) confirmed using the PCR method. The mean age of infected individuals was 41.7 ± 9.4 years. No statistical correlation was observed between inflammation, method of contraception and infection (p = 0.8). The present study revealed a relatively low prevalence of T. vaginalis infection within the study population. Additionally, the utilization of the PCR method can be beneficial in confirming suspected samples.
