SUMMARY:

Bovine anaplasmosis is responsible for causing hemolytic anemia, whose occurrence is influenced by factors related to the agent, host and vectors, related to significant economic losses to livestock. This paper is aimed to carry out an epidemological retrospective, clinical and hematological study of bovine anaplasmosis diagnosed at the Clínica de Bovinos de Garanhuns, Universidade Federal Rural de Pernambuco from January 2012 to December 2021. At first, the screening of clinical cases of the disease was carried out by consulting the institution's record book, subsequently the clinical records were rescued for information collection and construction of the database. The simultaneous identification of Anaplasma marginale in the blood smear, anemia and the presence of clinical signs were adopted as case selection criterion, with 230 clinical cases being selected, emphasizing that all cases that co-occurred with infections, including cases of bovine parasitic sadness. The descriptive-analytical statistical model was used, observing the distribution of data through relative and absolute frequencies. The disease represented 79.9% of the hemoparasites diagnosed at the institution. Females aged ≥24 months of European lineage and their crosses, reared under intensive and semi-intensive systems, 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, appetite impairment, 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 the severity of anemia. Anaplasmid drugs were effective in reducing parasitemia, which, together with blood transfusion, were fundamental for the clinical improvement of the patients. 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 on the dairy basin in the state of Pernambuco, making it important to adopt preventive measures as early as possible, particularly at the end of the rainy season for the dry season in region, helping to control the disease.
