[The detection of the surface antigens of Trichomonas vaginalis by using the scanning electron microscope].
The method for the detection of surface antigens, based on antibody aggregation phenomenon, was used in scanning microscopy of T. vaginalis. After Trichomonas treatment with immune blood serum diluted 1:5000--1:10,000 aggregates were detected, consisting of subunits 30-80 nm in diameter, localized on the protozoal cilia, projections, and, less frequently, body. Analysis of the results following the material treatment with colloid gold-conjugated anti-IgG permits a conclusion that the detected aggregates are antibodies to immunogenic surface antigens of T. vaginalis.
