4 cases of severe necrotising enteritis are dealt with. The small intestine was affected 3 times, the colon once, One patient died after resection of the affected bowel segment. In 2 additional cases a large resection of the small intestine became necessary. One patient was treated conservatively. The bacteriological evidence of Clostridium perfringens type C in the intestinal wall allows the assumption of a primarily bacterial genesis of this disease. Its aetiology, clinical and pathological-anatomic picture and the therapy are being discussed.
