Canine babesiosis is a hemoparasitosis caused by etiological agents of the Babesia genus. The use of clinical diagnosis is imprecise due to the existence of unspecific clinical signs, and routinely used tests such as the blood smear have many false negative results. Objective comparison of diagnostic efficiency by hematological patterns, blood smear, and by polymerase chain reaction (PCR). Method this is a research carried out with 80 dogs that were under the responsibility of the Zoonoses Control Center. By collecting 3 ml of venous blood per animal for testing. Results, there was mild to moderate anemia in the 80 samples analyzed, but without significant differences in the blood count parameters of dogs positive and negative for babesiosis. Although the diagnosis by blood smear was negative, PCR was 46.2% (37/80) positive for Babesia canis. A high rate of positive results for Babesia canis was identified in dogs parasitized by the vector tick. Final considerations from the
results found, it is concluded that there is weakness in the tests routinely used for the diagnosis of canine babesiosis when compared to molecular diagnosis. Evidencing the need to implement new methodologies for more efficient diagnosis.
