Double intussusception fatally complicated by clostridial infection in a dog (a case report).

A 10-month-old Alsation dog with history of anorexia, diarrhoea, dehydration and vomition developed a double intussusception which affected the distal jejunum and proximal ileum. Necropsy revealed the intussusception to be swollen and congested with fibrinous adhesions between the intussusceptum and intussuscepiens. Two pieces of bone believed to be the inciting cause were found within the intussusceptum. Clostridium welchii and Clostridium bifermentans were isolated from the lesions.
