A fairly frequent problem is infection by the urogenital protozoan Trichomonas vaginalis. It is perhaps the most common clinically recognized sexually transmitted disease in the United States, with about 2.5 million new cases occurring annually. Approximately 180 million new cases occur each year worldwide [1]. The infection has a continuous endemic source, for as many as half of the female carriers are totally asymptomatic. Newer treatments have greatly improved therapy for this disease, but diagnosis and the detection of carriers remain significant challenges. Symptomatic or asymptomatic urethritis or vaginitis due to T. vaginalis is the usual scenario. The spectrum of symptoms associated with this disease is wide. Ultimately, the diagnosis is established by identifying the causative organisms.
