Abstract
Monoclonal antibodies which react with culture forms ofTrypanosoma dionisii andTrypanosoma cruzi were tested for their agglutination capacity. In these studies developmental stage specificity for the epimastigote form could be observed. This specificity meant it was possible to develop a quick and simple method to isolate cultured metacyclic trypomastigotes ofT. dionisii andT. cruzi group 2. After agglutination of the epimastigote form with the monoclonal antibody Dion 4.6 the purity of metacyclic trypomastigote developmental forms derived from culture was 96% to 99%.
