Disease may also occur later if bacterial or plant-derived trypsin inhibitors are present in the feed.

Enteritis caused by C perfringens type E is rare but has been reported in goats, calves, and adult cattle. The main factor responsible for this age restriction is the susceptibility of the beta toxin to destruction by trypsin discussed further for C perfringens type C.
