Tick-borne diseases are of global economic importance, especially due to the costs associated with disease treatment and productivity losses in livestock. In this study, 244 livestock animals (cattle N = 92, buffaloes N = 86 and sheep N = 66) from Menoufia, Egypt were tested for Anaplasma, Ehrlichia and Babesia species using PCR. Results revealed detection of A. ovis (9.1%) in sheep while Anaplasma spp. (14.1%), A. marginale (15.2%) , B. bigemina (6.5%) and B. bovis (5.4%) in cattle. On the other hand, Anaplasma spp. (1.2%), A. marginale (1.2%) and B. bovis (1.2%), were detected in buffaloes. Significantly higher detection rates were observed in cattle for Anaplasma spp. (P =.020), A. marginale (P =.001) and B. bigemina (P =.022) than in buffaloes. Sequence analysis of Anaplasma spp. isolates from cattle, revealed A. platys- like strains. Phylogenetic analyses of the A. platys -like isolates revealed variation among the strains infecting cattle. The A. marginale buffalo isolate, on the other hand, showed some level of divergence from the cattle isolates. This study reports the first detection of A. ovis in sheep and A. platys- like strains in cattle in Menoufia and Egypt at large. The results of the current study provide valuable information on the epidemiology and genetic characteristics of tick-borne pathogens infecting livestock in Egypt.
