BABESIOSIS IN CAPTIVE NORTH AMERICAN POPULATIONS OF MANED WOLVES (Chrysocyon brachyurus)

摘要

Canine babesiosis is an important tick borne disease that is characterized by acute onset, hemolytic anemia and thrombocytopenia. Over the last 10 years, five cases of Babesia species have been diagnosed in maned wolves (Chrysocyon brachyurus) in U.S.zoos. Common presenting clinical signs are acute onset inappetance, vomiting, distended abdomen, and lethargy. Physical exam findings include icteric, pale mucous membranes, hypothermia, hyperthermia, severe dehydration, and brown to port-wine urine.5'6Clinical pathology usually reveals a severe hemolytic anemia with profound parasitemia on blood smears, thrombocytopenia, elevated urea nitrogen, hyperbilirubinemia, hypocalcemia and hypokalemia.
