Hemolytic activity for animals infected with various Babesia species is well reported. In this study, we confirmed that serum of Babesia rodhaini-infected mice also showed hemolytic activity. Erythrocytes from non-infected mice were lysed by co-incubation with B. rodhaini-infected serum. Catalase activity of the non-infected target erythrocytes was suppressed after this co-incubation with the hemolytic serum of B. rodhaini-infected mice. Furthermore, serum hemolytic activity was inhibited when target erythrocytes were incubated with hemolytic serum in the presence of exogenous catalase. Our study indicated that hemolytic serum can down-regulate the antioxidant capacity of non-infected healthy erythrocytes, possibly as a result of catalase activity, thereby leading to hemolysis.
