Prevalence of Trichomoniasis and Vulvovaginal Candidiasis among Married Women in Duhok City, Kurdistan Region, Iraq.

Trichomonas vaginalis and Candida spp. are the most common causes of vaginal infections among reproductive-age women. T. vaginalis is a sexual protozoa parasite that causes trichomoniasis. Candida spp. are fungal and cause infection in the female genital tract named candidiasis. Both microorganisms if not treated correctly may lead to various complications, such as abortion, premature delivery, disorders of menstrual cycle, and infertility. The current study aimed to study the frequency of infections with T. vaginalis and Candida spp., including C. albicans, C. krusei, and C. glabrata, among females with vaginal infection in Duhok City, Kurdistan region, Iraq. A total of 400 vaginal swabs were collected from women with vaginal infections that attended the Vin Private Laboratory (n=250) and Arveen Private Laboratory (n=150). Out of these 400 vaginal swabs samples, 24 samples were recorded positive for T. vaginalis by direct smear and 100 samples for candidiasis by culturing on the CHROMagar^TM Candida. Three species of Candida were isolated, namely C. albicans, C. krusei, and C. glabrata, and their prevalence rates were obtained at 60.9%., 28.25, 7.3%, and 3.6%, respectively. Vaginal infection was commonly found in the age group of 25-35 years (49.6%), followed by the age group of 35-45 years (36.4%). Moreover, 3.2% of samples were found to have a mixed infection with trichomoniasis and candidiasis. Because these two causative agents cause numerous complications in women, it is highly recommended proper controlling measures, such as health education, personal hygiene, and treatment of infected women, be implemented to prevent or decrease vaginal infection.
