Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Recognise the classic discharge pattern. A frothy, profuse, greenish vaginal discharge is the hallmark of trichomoniasis, a sexually transmitted infection of the child-bearing age group.
Step 2: Trichomonas vaginalis also produces multiple punctate "strawberry spots" on the vaginal vault and cervix, and culture is about 98% reliable for diagnosis.
Step 3: Candida albicans causes a thick, white, curdy discharge with itching, not a green frothy one, so option b is wrong. Herpes simplex causes painful genital ulcers, and normal flora gives no abnormal discharge, ruling out options a and d.
Step 4: Therefore the green frothy discharge points to Trichomonas vaginalis.
