Abstract

Anaemia and thrombocytopenia are common in blood parasite infection in dogs. The diagnostic investigation of non-regenerative anaemia (NRA) in canine practice is more challenging than regenerative anaemia.  A 4-year-old, intact non-descript male dog weighing 20 kg was presented to the clinics at Thrissur, Kerala with the complaint of continuous weight loss and inappetence for the past few weeks.  Major findings were splenomegaly, non-regenerative anaemia and thrombocytopenia. The dog was positive for Trypanosoma evansi and Babesia gibsoni by species-specific PCR.  The dog responded to treatment with diminazene aceturate, quinapyramine chloride/ sulphate and doxycycline.  This article reports non-regenerative anaemia and thrombocytopenia in a T. evansi – B. gibsoni natural mixed infection in a dog and its successful management. This article reinforces the importance of PCR-based tests in the diagnostic investigation of non-regenerative anaemia and thrombocytopenia.
