Abstract
Juvenile carps were used in the infection of Trypanosoma danilewskyi strain FCc 1 in the laboratory experiments to asses the protective immunity developed in fish after the clearance of trypanosomes from their blood. The fish recovered from infection were protected from re-infection as well as challenges of infection for at least until 195 days p.i. due to the presence of protective immunity. Fish can be passively immunized against Trypanosoma danilewskyi strain FCc 1 infection by injecting immune plasma from recovered fish. Moreover, the immune plasma was capable of lysing live trypanosomes at optimal temperatures. Fish can also be immunized by injecting lysed trypanosomes in immune plasma at 10°C and 20°C.
