Serological Survey of Babesia bigemina and Babesia bovis in Cattle and Water Buffaloes from Menoufia Province, Egypt.

Bovine babesiosis causes morbidity in tropical and subtropical countries worldwide. The present study aimed to determine the seroprevalence of Babesia bigemina and B. bovis in cattle and water buffaloes in Menoufia province, where the second-highest population of bovines in Lower Egypt are raised. A total of 506 blood samples were collected from cattle (N = 262) and water buffaloes (N = 244) in Menoufia province, Egypt. Seroprevalences of B. bigemina and B. bovis in the samples were determined using recombinant Babesia antigen-specific enzyme-linked immunosorbent assays (ELISA). In cattle, the seroprevalences of B. bigemina and B. bovis were 41.60 and 38.17% (37.40 and 35.88% for IgM and 9.54 and 6.11% for IgG), respectively, whereas those of water buffaloes were 35.66 and 31.97% (27.87 and 21.72% for IgM and 15.16 and 15.16% for IgG), respectively. Statistically significant changes in the seroprevalences of the two infective agents were recorded on the basis of region and season of sample collection. In conclusion, babesiosis is frequent and presents a threat of an epidemic among bovines in Menoufia province. In turn, control of bovine babesiosis is required because of its potential to detrimentally affect milk and meat production in Menoufia province.
