Beschreibungen/Notizen

• The aim of this study was to analyze the presence of 62 kDa proteinase and anti-62 kDa proteinase antibody in clinical samples of symptomatic and asymptomatic infected women. Proteinase was detected in all the swabs vaginal of infected women. Significantly, amounts of antigen (mean optical density (OD) values) were detected in swabs vaginal of symptomatic as compared to asymptomatic women. This protein was not detected in the group of patients with Trichomonas vaginalis-culture-negative results and in the groups of samples infected with other agents. Antibody to 62 kDa was detected in the swabs vaginal the only 66.6% of the symptomatic and 55.5% of the asymptomatic infected women. Antibody to 62 kDa was also detected in 7/30 of the swabs vaginal from uninfected women. No significant difference was observed in mean OD values of vaginal swabs of T. vaginalis-infected symptomatic as compared to asymptomatic women. The presence of proteinase in 100% of T. vaginalis-infected women suggested that 62 kDa proteinase could be a virulence factor.
