Conteúdo: 	This study aimed to determine the seroprevalence of Babesiosis and Anaplasmosis in cattle from the municipalities of Ouricuri and Petrolina, state of Pernambuco, Brazil, and to define the risk factors for the occurrence of the diseases. Blood samples were collected for serologic testing by Indirect Immunofluorescence Assay (IFA). Sanitary epidemiological questionnaires were applied to the producers aiming to identify possible risk factors. Ticks were collected, identified and tested by Polymerase Chain Reaction (PCR) for the diagnosis of infection by Anaplasma marginale, Babesia bigemina and Babesia bovis. The study was conducted with 861 cattle, being 468 in Petrolina and 393 in Ouricuri. The seroprevalence of A. marginale, B. bigemina and B. bovis in Petrolina was of 35.0% (164/468), 35.9% (168/468) and 32.3% (151/468), respectively; and in Ouricuri was 45.5% (179/393), 38.6% (152/393), and 54.9% (216/393), respectively. Co-infection for Anaplasma spp. and Babesia spp. was observed in 31.6% and 32.1% samples of Petrolina and Ouricuri, respectively. The detection of DNA of Babesia spp. by PCR was possible in 5.8% (8/137) ticks; which 62.5% (5/8) was detected later infection with B. bovis; and 23.3% (32/137) with A. marginale. The presence of ticks, the use of acaricide, age, race, and county of residence of the animals were identified as risk factors for TBD by univariate analysis and multivariate. This study allowed the characterization of the municipalities studied as enzootic instability areas for these hemoparasitic, and consequently alert for adoption of adequate control measures and new studies.
