History of Discovery

Trichomoniasis was first described by scientist Donne in 1836 . Donne identified the protozoan in an unstained “wet mount” preparation of vaginal discharge mixed with saline. In 1883, another researcher named Kunstle described the behavior of the parasite within the female urinary tract. One year later, Marchand identified the organism in the male urinary tract. All three men believed that the trichomonad was harmless and ubiquitous. As a result, doctors focused most of their efforts on the diagnosis and treatment of other sexually transmitted diseases such as gonorrhea and syphilis . It was not until almost 60 years later that doctors directed their attention towards T. vaginalis as a common cause of urogenital morbidity.
