Which STI is most commonly associated with a frothy, greenish vaginal discharge?

• A. Chlamydia
• B. Gonorrhea
• C. Trichomonas
• D. Syphilis

Answer: (C)

The presence of a frothy, greenish vaginal discharge is most commonly associated with Trichomonas, a sexually transmitted infection (STI) caused by the protozoan parasite Trichomonas vaginalis. This particular discharge is a hallmark symptom of the infection, alongside other potential signs such as itching, irritation of the vulva, and dyspareunia (pain during intercourse). Trichomoniasis is often characterized by a distinctive "frothy" appearance resulting from the inflammation and irritation of the vaginal mucosa caused by the organism. It's essential to note that this STI can be asymptomatic, but when symptoms are present, the frothy discharge is quite noticeable. The differentiation from other infections is based on the discharge's appearance. For instance, Chlamydia and Gonorrhea generally cause a more purulent or mucopurulent discharge, usually yellow or white, without the frothy quality seen in Trichomonas. Syphilis, on the other hand, does not typically present with vaginal discharge as a symptom but rather with other systemic manifestations such as chancres and skin rashes. Recognizing the characteristics of the discharge is critical for diagnosing Trichomonas, allowing for appropriate management and treatment.
