Tips

PHF (Potomac Horse Fever) is a disease frequently seen in horses that causes gastrointestinal upset, including diarrhea and enteritis. Neorickettsia risticii and Ehrlichia risticii cause PHF. These are organisms that tend to live in many cells within a horse's body. PHF may also be called equine ehrlichial colitis or equine monocytic ehrlichiosis.
