Trich·o·mo·nas va·gi·na·'lis

a species frequently found in the vagina and urethra of women (in whom it causes trichomoniasis vaginitis) and in the urethra and prostate gland of men (the only known natural hosts); considerable differences in pathogenicity exist among various strains of this species.

Trichomonas vaginalis

A species found in the vagina that produces discharge. T. vaginalis is fairly common in women, esp. during pregnancy or following vaginal surgery. It is sometimes found in the male urethra and may be transmitted through sexual intercourse. See: illustration; colpitis macularis

Symptoms

T. vaginalis causes persistent burning, redness, and itching of the vulvar tissue associated with a profuse vaginal discharge that may be frothy or malodorous or both. Occasionally, infection with T. vaginalis is asymptomatic.

Treatment

Metronidazole (Flagyl) is taken orally by the woman and her sexual partner. The drug is contraindicated during the first trimester of pregnancy because of potential damage to the developing fetus; clotrimazole vaginal suppositories provide symptomatic relief during the first 12 weeks of gestation.

CAUTION!

Alcohol should not be consumed during metronidazole therapy.

It is difficult to assess the implications this study has for clinical practice due to the wide variety of infections (Cardnerella vaginalis, Escherichia coli, Streptococcus, Staphylococcus, Chlamydia trachomatis, and even Trichomonas vaginalis), and due to new knowledge we now have as far as the high rate of resolution of CIN I and even high-risk HPV without any treatment at all.
