PCR detection of Babesia ovata from cattle reared in Japan and clinical significance of coinfection with Theileria orientalis

Abstract

We describe here the clinical significance of coinfection with Theileria orientalis and Babesia ovata in cattle. Anemia status in a herd of dairy cattle in Japan was investigated in relation to infection with these parasites. Our findings indicate that while B. ovata infection might not be the primary cause of anemia in the cattle, it may contribute to the clinical development of anemia in animals coinfected with both B. ovata and T. orientalis.
