Question

a 22-year-old woman complains of a greenish \fishy\ malodorous vaginal discharge that itches. what is the most likely organism responsible for her discharge?
chlamydia trachomatis
trichomonas vaginalis
neisseria gonorrhea
candida albicans
genital herpes simplex ii

Explanation:

To determine the most likely organism, we analyze the symptoms: greenish, "fishy" malodorous vaginal discharge with itching. Trichomonas vaginalis causes trichomoniasis, which presents with these symptoms (greenish, frothy, malodorous discharge, itching). Chlamydia and Neisseria cause mucopurulent discharge without the "fishy" smell. Candida causes white, curdy discharge (not greenish/fishy). Genital herpes causes ulcers/vesicles, not this discharge pattern.

Answer:

B. Trichomonas vaginalis
