Cyclic changes in vaginal populations of experimentally induced trichomonas vaginalis infections in rhesus monkeys

It is generally observed by clinicians that exacerbations of human vaginal trichomoniasis occur around the time of menstruation and that symptoms are usually more severe during this interval. However, detailed studies on the trend of parasite population in individual patients seem not to have been reported. Such facts, if available, could be of importance in diagnosis and in assessing the efficacy of a therapeutic regimen. It is the purpose of the present study to report observations on the course of the infection in monkeys, with the hope that similar studies on strictly isolated human patients may be forth-coming.
