This is the first report of Babesia vogeli molecular detection in dogs from the state of Acre, northern Brazil. This study aimed to perform the molecular detection of Babesia vogeli in dogs in the municipality of Rio Branco, Acre. Blood samples were collected from 47 dogs presenting with clinical signs comparable to hemoparasitosis. These were dogs which were attended in veterinary clinics from Rio Branco municipality, Acre. Physical examinations, packed cell volume (PCV) determination, platelet number estimation, hemoparasite investigation in the blood (collected from the pinna and peripheral blood), and polymerase chain reaction (PCR) for piroplasm based on the 18S rRNA gene, were performed. One dog (1/47, 2.1%; CI 95%: 0.1-11.3%) tested positive to Babesia vogeli in the polymerase chain reaction (PCR) assay for piroplasms and the resulting sequence showed 100% identity with Babesia vogeli isolates deposited in GenBank®. Co-infection with Ehrlichia spp. was also observed by direct examination (via blood smear). The clinical and hematological alterations observed in the positive animal were anorexia, dehydration, white mucous membranes, anemia and thrombocytopenia.
