Ruth Correll: Potomac horse fever identified nearby
Potomac horse fever is an acute gastrointestinal disease that can result in mild colic, fever and diarrhea in horses of all ages, as well as abortion in pregnant mares. Initially, the disease was named due to the number of cases along the Potomac River in the eastern United States. It has also been referred to as ditch fever, Shasta river crud and equine ehrlichial colitis. The causative agent is neorickettsia risticii, a gram-negative bacteria that was identified in freshwater snails. The disease is commonly seen in spring, summer and early fall and associated with pastures bordering creeks, rivers or irrigated pastures.
