Conteúdo: | Trypanosoma evansi is a salivarian trypanosome belonging to subgenus Trypanozoon. It is the causative agent of Surra in the Old World and Mal de Caderas in the subtropical area of Argentina and Pantanal, Brazil. Different methods are used for protection against salivarian-trypanosome infection: a) infection with irradiated trypanosomes, b) infection withtrypanosome components and c) infection and quimiotherapy. Only the ultimate is used with successful results for homologus but not heterologous challenges. Survival of acute Trypanosoma cruzi infection has been suggested to be develop in naturally susceptible host and can be enhanced in inherently resitant animals by prior immunization. Highly susceptible C3H/He strain of laboratory mice can be protected from an otherwise lethal infection by prior immunization with an avirulent T. cruzi strain. Enhanced resistance of Balb/c mice to T. congolense infection with... but not... of homologous variants was related. Also has been reported protection its conferred for non-surface compionents antigens in homologous T. evansi challenge. Athimic mice are capable of control T. brucei and T, rhodesiense replication and become resistant to subsequent challenge with homologous parasites.
