Blood samples from 300 calves were collected, followed by DNA extraction and nested PCR using oligonucleotide primers to amplify fragments of the semi-nested for the msp5 gene (A. marginale), sbp-4 (B. bovis) and rap-1a (B. bigemina) Among the examined calves, the prevalence of A. marginale was 55.6% (n=167\/300), B. bovis was 4.0% (n=12\/300) and B. bigemina was 15.3% (n=46\/300), by PCR techniques. Parasitic forms of A. marginale and B. bigemina were found in 36,3% and 2,6% of the blood smears while B. bovis was not detected. There was a statistical difference between the positivity of infected animals in the age groups 1 (10-70 days) and (&gt;70-300 days) for A. marginale and B. bigemina. A total of 15 calves with the classic symptoms of disease were examined, and the samples obtained were confirmed as a simple infection by A. marginale through semi-nested PCR. These results confirm bovine anaplasmosis as the primary cause of CTF among the calves of dairy cattle within the studied area.<\/jats:p>","DOI":"10.1590\/s1984-29612020011","type":"journal-article","created":{"date-parts":[[2020,4,11]],"date-time":"2020-04-11T19:21:14Z","timestamp":1586632874000},"source":"Crossref","is-referenced-by-count":12,"title":["Characterization
