L’analyse antigénique de Trichomonas vaginalis, par les techniques de diffusion en gel et d’immunoélectrophorèse, semble révéler qu’il existe une différence qualitative entre 2 clones (A2, A3) d’une même souche, aussi bien qu’entre un clone « jeune » et un clone « vieux », c’est-à-dire en culture depuis 12 mois, provenant d’un même clone initial. Les absorptions croisées réduisent le phénomène à une différence quantitative, ce qui remet en question les variations antigéniques signalées chez Trichomonas.
Abstract
Antigenic analysis of Trichomonas vaginalis by gel diffusion and immunoélectrophoretic technics released indications that there seemed to be a qualitative difference between 2 clones (A2, A3) of the same strain, as well as between a young clone A2 and an old one (the latter having been in culture for 12 months) both of them originating from the same initial clone. Such differences are reduced to quantitative level by the results of cross absorptions. Antigenic variations mentionned by the previous authors are to be questionned.
