We are trying to find some information on
dryland distemper in horses. Can you send us any info you might have?
The bacteria which causes this disease is
Corynebacterium pseudotuberculosis. The condition is also known as Pigeon fever due to the development of abscesses in
the ventral and pectoral region.
It is worldwide in distribution, the most common presentation is that of ulcerative lymphangitis, a severe
cellulites
of one or more legs. Other clinical signs include anorexia, lethargy, fever,
lameness and development of many small
draining sores. It often becomes a chronic condition resulting in chronic lameness and weight loss.
In the U.S., dryland distemper is most common in the west, particularly in California. It is characterized by pectoral,
ventral midline and inguinal abscesses. A large area of edema is usually associated with the abscess, which are
initially very hard. Fevers are moderate (up to 103). The process of abscess development can go on for several months
and once it is lanced, will generally resolve without further complication. Certainly a percentage of cases (10%)
develop recurrent problems and 1-2% will develop internal abscesses.
The usual treatment recommendations include:
1) Lancing the abscess.
2) Use of an appropriate antibiotic. (also read about Fastrack)
3) Use of no steroidal anti-inflammatory agents.
