Trichomonas

 [trik″o-mo´nas]
a genus of flagellate protozoa parasitic in birds and mammals, including humans. T. ho´minis and T. te´nax are nonpathogenic species found in the human mouth and intestines. T. vagina´lis is found in the vagina and male genital tract and is the cause of trichomoniasis.

Trichomonas

(trik'ō-mō'nas, trik'ō-mon'as), Although the correct pronunciation of this word is trichom'onas, the pronunciation shown is more commonly heard in the U.S.
A genus of parasitic protozoan flagellates (subfamily Trichomonidinae, family Trichomonadidae) causing trichomoniasis in humans, other primates, and birds. Specificity is more marked for its precise microhabitat than for host species. The genus has been divided into several genera: Trichomonas, Pentatrichomonas, Tetratrichomonas, and Tritrichomonas.

Trichomonas

[trik′əmon′əs]
a genus of flagellate protozoa that includes many species that are parasitic. Some live in the mouth of humans and are found around carious teeth. Other species are found in the vagina and urethra of women. They are a cause of trichomoniasis.

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.
