VESICAL INFECTION WITH TRICHOMONAS VAGINALIS

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.
