Conditions or ailments that are the cause of a problem that you see - your observation.

Your vet may diagnose

Salmonella Colitis (in Growing Foal or Adult)

Synonyms: Paratyphoid, Non-typhoidal Salmonellosis


Salmonella is the most common cause of bacterial colitis in the horse. It causes severe, usually foul smelling diarrhea, life threatening dehydration, endotoxemia, and shock.

It is a common cause of hospital borne infection. In past years, Salmonella outbreaks have forced many large private and veterinary school hospitals to close and institute quarantine and bio-security protocols.
