Trypanosoma cruzi infection in a dog from Oklahoma.
A dog with signs of weakness, labored breathing, and generalized edema was examined. It was heavily infested with fleas and had wounds resulting from a recent fight. Hematologic findings were not remarkable, except for parasites in the blood. The dog was treated for fleas and given antibiotics, but was euthanatized when it failed to respond. Blood and tissue specimens were found to contain Trypanosoma cruzi, and the serum contained antibodies to the organism. We believe this is the first confirmed case of T cruzi infection in dogs from Oklahoma. The public health implications of this finding are underscored by a report on the detection of T cruzi in raccoons in the same season and geographic area.
