A Report of a Hepatozoon Canis Infection in a Dog with Transmissible Venereal Tumour

Abstract In the present study, a case of a Hepatozoan canis infection in a dog with a sexually transmissible venereal tumour is reported. Haematological examination revealed marked decrease in haemoglobin, PCV and RBC counts and the blood smear revealed rouleaux formation of RBC, hypochromasia, leptocytes and neutrophilia. Neutrophils were parasitized with both non-nucleated and stained nucleated forms of H. canis. Serum biochemistry results showed elevated levels of alkaline phosphatise, whereas blood urea nitrogen, creatinine, total protein, albumin and globulin were in the normal range.
