Among the major diseases that affect cattle and water buffaloes, the tick-borne diseases are detaches. Bovine babesiosis caused by Babesia bigemina and Babesia bovis, and anaplasmosis, caused by Anaplasma marginale rickettsia, are of great economic importance to cattle diseases. The aim of this study was to compare the serologic occurrence for the agents of tick fever in cattle and water buffaloes in the middle region southeast of the state of Pará, northern Brazil. Blood samples were collected from 679 beef cattle (Nelore) and 430 water buffaloes (Mediterranean and Murrah) in eight cities of middle region southeast of Pará, Brazil. The research of antibodies IgG against A. marginale, B. bigemina and B. bovis was performed through of the indirect enzyme-linked immunosorbent assay (iELISA). Cattle compared to buffaloes showed higher occurrence of antibodies against B. bovis (97,34% and 33.95%), B. bigemina (97,34% and 27.21%) and A. marginale (74,52% and 47.90%), respectively. The probability of cattle are serologically positive to A. marginale, B. bovis and B. bigemina was 1,5 (74,52/47,90%), 3,58 (97,34/27,21%) and 2,87 (97,34/33,95%) times higher than that buffaloes, respectively. These results suggest that buffaloes may be more resistant to vectors being subjected to a lower rate of infection than cattle.
