Abstract
Ten cattle were infected or superinfected with Trypanosoma spp. of the subgenera Nannomonas (T. congolense), Duttonella (T. vivax) and Trypanozoon (T. brucei), respectively. The complement fixation test (CFT) and the indirect fluorescent antibody test (IFAT) were employed to investigate the possible differentiation of subgenera by serological methods and the persistence of antibodies. The serological results were compared with parasitological and hematological findings. After monospecific infections and most superinfections a subgenus differentiation of antibodies was possible with the IFAT, but not with the CFT. Specific antibodies were demonstrated 285 days after the last parasites were seen.
