Plain-English summary

A 2.5-year-old male German Shepherd in Vietnam was brought to the vet because he was not eating, seemed weak and tired, and didn't want to go for walks. He also had a fever and showed signs of pale gums and swelling in his back legs. Blood tests revealed he had severe anemia and other issues, and the vet found a parasite called Trypanosoma evansi in his blood. This case is notable as it's the first reported instance of this parasite affecting dogs in Vietnam. Treatment details were not provided, but identifying the cause is a crucial first step for recovery.

Abstract

A 2.5-year-old male German Shepherd was presented to a private veterinary clinic in Hanoi, Vietnam showing anorexia, weakness, lethargy, reluctant to go for walks with a recent history of intermittent fever. Clinical examination of the dog showed pale mucous membrane, impaired eyesight, edema of the back legs. Complete blood count revealed severe anemia; red blood cell 3.8 × 1012/l, hemoglobin 8.7 g/dl, hematocrit 26.4%, associated with thrombocytopenia 145 × 109/l. Biochemical analysis showed a moderate increase of alanine transaminase (150.7 UI/l) and alkaline phosphatase activities (266 UI/I) with mild hypoglycemia (71.46 mg/dl). Trypanosoma evansi was observed in Giemsa-stained blood smears under microscopic observation which was confirmed by PCR. This is the first report of canine trypanosomiasis caused by T. evansi in Vietnam.
