Abstract: A 5‐month‐old intact male Boerboel dog, imported from South Africa 1 week previously, was presented to a Texas veterinarian for lethargy, anorexia, and labored breathing. The dog was febrile, anemic, leukopenic, thrombocytopenic, and slightly azotemic. Results of the IDEXX SNAP‐4Dx enzyme immunoassay were negative for Dirofilaria immitis antigen and antibodies against Ehrlichia canis, Borrelia burgdorferi, and Anaplasma phagocytophilum. An EDTA blood sample analyzed at Oklahoma State University Center for Veterinary Health Sciences revealed nonregenerative anemia, neutropenia, and large protozoal piroplasms in 0.7% of the RBCs. Piroplasms were 2–5 μm long and varied in shape from round to oval to piriform; extracellular merozoites were also observed. Nested PCR was per…
