Abstract
Canine monocytotropic ehrlichiosis and thrombocytotropic anaplasmosis are frequent infectious diseases in small animal medicine. They are caused by obligate intracellular bacteria transmitted by ticks that have a variable incubation period and unspecific clinical signs, being considered multisystem diseases, so the importance of laboratory evaluation and the use of serological tests such as immunochromatographic tests that help the clinician in the diagnosis. Therefore, the objective of the present study was to determine the frequency of hematological and biochemical alterations in dogs diagnosed with ehrlichiosis and anaplasmosis using immunochromatographic serological test. A retrospective study was carried out between 2015 and 2021 with dogs from the routine of the Roque Quagliato Veterinary Hospital that had a diagnosis based on history, laboratory evaluation and immunochromatographic serological test reactive for canine monocytic ehrlichiosis and canine thrombocytic anaplasmosis. The hemogram was performed in an automated veterinary cell counter and in stained blood smears using optical microscopy and biochemical analyzes were performed in a semi-automated photocolorimeter. The most frequently observed changes in the erythrogram were reduction of red blood cells, hemoglobin and hematocrit, lymphopenia was common in the leukogram, thrombocytopenia in the plateletogram, in addition to serum and plasma hyperproteinemia, concomitantly with hyperglobulinemia and hypoalbuminemia. It is concluded that some hematological and biochemical alterations occur more frequently in seroreactive dogs for ehrlichiosis and anaplasmosis, which may help in the diagnosis of these hemoparasitoses.
