What causes equine enteritis?
• Intestinal horse parasites such as roundworms and small strongyles can inflame the lining of the intestines.
• Sand and gravel can irritate the lining of the intestines and cause inflammation, as can the ingestion of poisonous plants or chemicals.
• A bacteria, Clostridium perfringens, may cause an intestinal inflammatory reaction. Enteritis is more common in the southeastern US, possibly due to naturally occurring soil bacterium.
