Serum of Babesia rodhaini infected mice down regulates catalase activity of healthy erythrocytes

► Healthy erythrocytes from un-infected mice were destructed after co-incubated with B. rodhaini-infected serum. ► Catalase activity of healthy erythrocyte was suppressed after co-incubated with hemolytic serum. ► In the presence of exogenous catalase, serum hemolytic activity was inhibited.
