Trichomoniasis Trichomonas vaginitis is caused by Trichomonas vaginalis, a microscopic organism.
Some women have no symptoms.
Male sexual partners rarely display symptoms. Diagnosis is usually made by identifying the motile or moving organism under the microscope. Treatment of both partners is recommended since trichomonas vaginalis is readily transmitted by sexual contact. Treatment involves the use of an oral medication called metronidazole. Alcoholic beverages should not be consumed while taking the medication and 24 hours before and thereafter.
