Q

what is the pathophysiology of anterior enteritis?

A

Clostridium difficile spores ingested and enter the stomach > spores then pass through pylorus to reach the duodenum > proximal SI rich in bile acids secreted via major duodenal papilla > spores interact with bile and germinate into vegetative cells > cells multiply, colonize, and produce toxins > epithelial damage and inflammation > ileus and colic signs
