Trichomonas vaginalis is a protozoan parasite of the urogenital tract in men and women and causes a sexually transmitted disease, trichomoniasis, in about half of infected women. Infections are associated with pelvic inflammatory disease, adverse pregnancy outcomes, infertility, an increased incidence of aggressive prostate cancers, and an increase in HIV-1 transmission.
