Seroepidemiologic studies on Babesia equi and Babesia caballi infections in horses in Jilin province of China.
The prevalence of equine piroplasmosis caused by Babesia equi and Babesia caballi in northeast China has remained unknown, although the People's Republic of China is recognized as an endemic country for the diseases. In the present study, we investigated the prevalence of equine piroplasmosis in Jilin province, a part of northeast China. A total of 111 serum samples were taken from horses in eastern Jilin, and examined for diagnosis of B. equi and B. caballi infections by the enzyme-linked immunosorbent assays with recombinant antigens, equi merozoite antigen-1 and P48, respectively. Of the 111 samples, 38 (34%) and 36 (32%) samples were sero-positive for B. equi infection and B. caballi infection, respectively. In addition, 14 (12%) samples were sero-positive for both B. equi and B. caballi infections. These results indicate that equine piroplasmosis is widespread and therefore a cause for serious concern in northeast China.
