Isosporosis among stray pups

Canine isosporosis is an enteric disease caused by the genus Isospora characterised by severe colitis and enteritis. The present study involved 12 non-descript stray pups of 2–3 months age which had diarrhoea, anorexia, dullness and found positive for Isospora canis by floatation method. On physical examination, pale mucous membrane, sub-normal temperature and dehydration were noticed. Haematology revealed anaemia (reduced haemoglobin, total erythrocyte count and packed cell volume). Pups were treated with sulphonamide trimethoprim @ 15 mg/kg intravenously for 5 days along with fluid therapy and iron supplementation. Marked clinical improvement was noticed by five days. The haematological parameters showed significant improvement after treatment.
