Sections of the small intestine were taken under general anaesthesia from a normal calf and from a calf with enteric colibacillosis and examined by scanning electron and light microscopy. In the normal calf villi were long and oval throughout the intestine and in the challenged calf there was villous stunting and fusion in the distal small intestine.
