Isolation, cultivation, low temperature preservation, and infectivity titration of Trichomonas vaginalis.

Abstract

The diagnosis of Trichomonas vaginalis (Donne, 1837) infection by direct recognition of the parasite is comparatively easy in the acute phase in the female, more difficult in the male and in the female in the non-acute phase. Because of this difficulty con- clusive epidemiological studies on T. vaginalis infection are few. We considered that immunological studies might improve the diagnosis of T. vaginalis infection and facilitate studies on the epidemiology and clinical significance of this organism.
