The aim was to carry out a retrospective study of bovine anaplasmosis diagnosed at CBG/UFRPE over a period of 10 years. Descriptive analysis of epidemiological, clinical and hematological data from 230 clinical records was performed. The disease represented 79.9% of the hemoparasites diagnosed at the institution. Females aged ? 24 months of European lineage and their crosses, reared in an intensive and semi-intensive system, were the most affected. As for seasonality, a higher occurrence of the disease was observed in the months of August to December. The most frequently observed clinical findings were apathy, decreased appetite, icteric mucous membranes and tachycardia. Abortion occurred in 12.8% of pregnant cows. Hematological findings revealed regenerative anemia, whose greater intensity of medullary response was associated with anemia severity. Antimicrobials (oxytetracycline LA and enrofloxacin) were effective in reducing parasitemia, which, together with blood transfusion, were essential for the patient's clinical improvement. Clinical resolution with hospital discharge occurred in 82.6% of patients with a mean hospital stay of eight days. Anaplasmosis was the most frequent hemoparasitosis in the care provided by CBG/UFRPE, confirming the economic impact, and it is important to adopt measures to guide producers in the region, especially at the end of the rainy season for the dry season, so that the diagnosis and disease treatment are carried out as early as possible, allowing a faster recovery and return of the animals to production, minimizing the economic impact that the dairy basin of the state of Pernambuco.
