Clinico-pathological findings and coagulation disorders in 45 cases of canine babesiosis in Spain.

A retrospective study of clinical cases of babesiosis in dogs examined at the Veterinary Teaching Hospital, Rof Codina, from January 2003 to October 2004 is presented. The diagnosis was confirmed by direct observation of large piroplasms in stained blood smears. Dogs with concurrent diseases were excluded from the study. Clinical signs, complete blood count, serum biochemistry and hemostasis profiles were obtained. The observed clinical signs were due to hemolytic anemia and inflammatory responses but the most relevant clinico-pathological findings were related to alterations in hemostasis. All dogs presented with thrombocytopenia and 20% had disseminated intravascular coagulation syndrome. Anemia of variable severity was observed in most of the dogs.
