Background: Trichomoniasis resulted in negative health issues that may be connected to infertility and pelvic inflammatory disease. Objectives:This study aimed to find an evidence of a link between T. vaginalis and various pelvic organs, such as adnexal, cervical, and vaginal erythema, friability, and mucopurulent discharge. Patients and methods: One hundered and sixty married women who visited some private clinics in Baghdad between October 2020 and February 2021 were included in the study. Lower abdominal pain and vaginal discharge were both present in all of these women. The women were split into two groups: those with pelvic inflammatory disease (PID) (n=41) and those without (n=119). All woman had pelvic and vaginal organs examination and vaginal swabs were obtained. Results: The research showed a strong association between T. vaginalis and pelvic inflammatory illness (P<0.05). The results showed that vaginal erythema (60%) and other symptoms such as cervical friability (21.7%), cervical motion discomfort (13.3%), and adnexal tenderness (26%), were not significantly associated to T. vaginalis positive diagnosis. While the correlation between T. vaginalis positivity and mucopurulent discharge was significant (P< 0.05). Conclusions: This research provided information on several clinical traits of trichomoniasis in women with PID. T. vaginalis was very predictable among adult female who had PID.
