Protozoa - Trichomoniasis

Trichomoniasis

Caused by Trichomonas vaginalis

This protozoa has no cyst form.
Thus, its trophozoites, which can’t survive outside the host, are transmitted during sexual contact in urogenital secretions.
Trichomoniasis is the most common non-viral STI in the United States.

– However, most infected individuals, especially males, are asymptomatic carriers. – When symptomatic, trichomoniasis produces vaginitis or urethritis, and sometimes prostatitis. – Vaginitis and urethritis are characterized by a burning, itchy sensation, and may be accompanied by a foul-smelling “frothy” discharge. Trichomonas vaginalis morphology* – Oblong shape – Axostyle runs the length of the body and extends posteriorly – Four anterior flagella, and the undulating membrane, which is a modified fifth flagellum.
