Question: What are the characteristics of trichomoniasis?

Answer:

Trichomoniaisis is an STD caused by a unicellular organism, Trichomonas vaginalis. Women present with pruritus and increased discharge. On exam, the discharge can be copious. The pH is elevated. Examination of the vaginal fluid in a saline preparation under high power (400x) shows the organism. Trichomonads are tear-shaped or ovoid, mobile, and flagellated. They are usually identified by their motility and their visible flagella.
Treatment is with a single dose of oral metronidazole (Flagyl). Treatment is usually highly effective, but there can be resistant cases requiring a longer course of therapy. Sexual contacts should also be treated.

    Yeast infections are not considered to be sexually transmitted infections (STI) because a celibate woman can develop them, but having unprotected sex can pass them along. A man who has unprotected sex with a woman who has an active yeast infection can get a penile yeast infection. Transmission of genital yeast infections from woman to man is uncommon, but it does happen.
