Prevalence
Most cases of cytauxzoonosis in the United States are reported from the southeastern and south-central states between March and September, when the tick vectors are active. However, disease due to C. felis also occurs in the mid-Atlantic states and upper Midwest and on the West Coast.
Diagnosis
Clinical pathologic changes in cats with C. felis include non-regenerative anemia, leukopenia, thrombocytopenia, elevated liver enzymes, hyperbilirubinemia, and hypoalbuminemia. Bilirubinuria is also a common finding.
