Serological diagnosis of babesia bigemina infecting Egyptian cattle and buffaloes

ABSTRACT

In the present study, the obtained results showed that a total incidence of 7.26%, 10.19%, 19.72% and 71.56% as well as 5.91%, 7.86%, 16.25% and 16.32% of B. bigemina infected cattle [1364] and buffalos [203] and that through examination by thin blood films, capillary tube agglutination test, indirect hemagglutination test and indirect ELISA technique respectively. Hence, the incidence of B. bigemina among buffalos was found to be lower than among cattle. Concerning the seasonal incidence of B. bigemina, it was noticed to be predominated in both summer and autumn and less in spring, while it reached its lowest peak in winter among both cattle and buffalos recording an incidence rate of 16%, 10%, 8.46% and 4.55% among cattle and 11.3%, 8%, 7.62% and 4% among buffaloes using the C. A. test respectively. Using the IHAT, the incidence rates were 28.81, 21.69%, 16.09% and 12.13% in cattle as well as 20.31%, 16.98%.13.33% and 12.19% in buffalos, respectively. While, 90.32%, 87.50%, 84% and 58.26% in cattle as well as 20%, 18.18%, 15.38% and 10.69% in buffalos were obtained by means of ELISA test, respectively
