Immune response and degree of protection in mice immunized with Trichomonas vaginalis antigen

The immune response and degree of protection of mice immunized with T. vaginalis sonicated antigen injected by intraperitoneal route, intraperitoneal and intravaginal only has been studied. Humoral response has been evaluated by indirect immunofluorescence and agglutination techniques; moreover, cytotoxicity of vaginal secreta has been investigated. Cellular response has been evaluated by stimulation of peripheral lymph-node cells and spleen lymphocytes with T. vaginalis antigen. It has been observed that inoculation by intraperitoneal plus intravaginal route induced a marked humoral and cellular response and a greater degree of protection.
