Partial Purification of Integral Membrane Antigenic Proteins from Trypanosoma evansi That Display Immunological Cross-Reactivity with Trypanosoma vivax.

Trypanosoma evansi and Trypanosoma vivax, which are the major causative agents of animal trypanosomosis in Venezuela, have shown a very high immunological cross-reactivity. Since the production of T. vivax antigens is a limiting factor as this parasite is difficult to propagate in experimental animal models, our goal has been to identify and isolate antigens from T.
