Trichomonas vaginalis is a protozoan belonging to the group of flagellates which was long considered nonpathogenic. Recently several gynecologists, notably Davis1 of Milwaukee and De Lee2 of Chicago, have reported many cases of irritating vaginitis due to it, and considerable doubt has been raised concerning its harmlessness.
Marchand3 was the first to report a case of infection of the bladder with this organism. Miura,4 Davis,5 Dock,6 Baatz,7 Arnold,8 Kunstler,9 Escomel,10 CČapek,11 Dastidar,12 Rasmussen,13 and Lewis and Carroll14 have since reported similar cases. Most of these observers report single cases, so that this condition is certainly not common. In some cases the infection caused an irritating urethritis in the male, and in one case, described at length by Lewis and Carroll,14 it caused a severe acute pyelitis. The case reported here resembles closely the one described by them.
