[Urogenital trichomoniasis and vaginal mycosis in female offenders--a repeat study 20 years later].

The prevalence of urogenital trichomoniasis and vaginal mycosis in 698 female prison inmates in Bratislava was compared with the occurrence of the diseases recorded twenty years ago. The occurrence rate of urogenital trichomoniasis (40.97%) was only slightly reduced compared to the sixties (59.

Differential susceptibility of fresh Trichomonas vaginalis isolates to complement in menstrual blood and cervical mucus.

The ability of complement in human menstrual blood and cervical mucus to kill Trichomonas vaginalis was compared with that of complement in serum, and 95 fresh trichomonal isolates obtained from vaginal wash material were evaluated for susceptibility to complement immediately after isolation. Only serum and menstrual blood with haemolytic activity produced total cytolysis of T vaginalis. The cytolytic abilities of these fluids were totally inactivated by treatment with heat or edetic acid (EDTA), which confirms the role of complement in cytolysis.

Fewer Trichomonas vaginalis organisms in vaginas of infected women during menstruation.

The aims of the present study were to count Trichomonas vaginalis organisms recovered from the vaginas of patients with trichomoniasis, and to obtain data concerning changes in sizes of trichomonal populations during the menstrual cycle. In about 80% of symptomatic as well as symptomless patients, more than 1 x 10(5) parasites per ml could be obtained from vaginal washes. During menstruation, however, the number of trichomonads decreased appreciably, with subsequent increases within three to six days after bleeding.

Phenotypes and protein-epitope phenotypic variation among fresh isolates of Trichomonas vaginalis.

Fresh isolates of Trichomonas vaginalis were examined for reactions to a panel of five monoclonal antibodies (MAbs). Four MAbs (C20A3, DM126, DM116, and C55) were to distinct surface immunogens and one MAb (L64) was to a cytoplasmic component. The fresh isolates were evaluated by indirect immunofluorescence (IF), immunoblotting, and radioimmunoprecipitation.
