Abstract

This article aims to describe seven cases of dogs naturally infected with Rangelia vitalli. Clinical findings, hematological parameters, parasitological diagnosis, and treatments were evaluated. On physical examination, these animals showed pale mucous membranes, hyperthermia, apathy, and blood dribbling down from the ear margins. R. vitalli merozoites were observed inside of erythrocytes, neutrophils, and macrophages in blood smear. Important hematological findings observed in these cases were severe anemia and thrombocytopenia. The animals were treated with therapeutic protocol based on prednisone, doxycycline, and dipropionate which had great curative efficacy to rangeliosis.
