Relapse of infection in single and mixed trypanosome infections in rats after diminazene aceturate treatment

Four groups (A, B, C and D) of 10 rats in each group were used to investigate relapse of infection in single and mixed trypanosome infections. Groups A served as uninfected control, groups B and C were infected with Trypanosoma brucei (Wamba strain) and T. congolense (Federe strain), respectively, and group D was infected with both species (50% of each species in the infective inoculum). Each infected rat received 1×10 6 trypanosomes
