Animal owners beware

I was warned a few days ago that our neighbors horses had all come down with Pigeon fever and was warned to keep a good eye on Peaches as well. I hadn't a clue as to what "Pigeon fever" was so I looked it up online. This is what I found.


Pigeon Fever
Cases of pigeon fever have once again been reported throughout Oregon, particularly in the Central and Eastern part of the state. Caused by the bacteria Corynebacterium pseudotuberculosis, pigeon fever is highly contagious, but rarely fatal. The disease is seasonal, with peak incidence in the fall months, and the incidence fluctuates from year to year within a site.

It is characterized by intramuscular abscesses, primarily in the pectoral area and ventral part of the abdomen, which gives the horse a puffed-out appearance similar to that of a pigeon. The infection is confirmed with a bacterial culture and by symptoms. Horse should be checked daily; look closely at the underside and check for swelling. In some cases, the infection can spread to the horse’s legs, causing a syndrome called ulcerative lymphangitis, which is difficult to treat.

The bacteria lives and multiplies in dry soil and manure. Hot, dry weather facilitates this bacterial growth. Horses contract the disease through an open wound or fly bite, with bacteria entering through these abrasions or wounds and, sometimes, mucous membranes. Fly control (sprays, sheets and repellents) can help to limit disease risk.

Humans can also be carriers of the bacteria on their boots, hands, and tools. Proper disinfection protocols should be utilized to limit the spread of the bacteria. Bedding, water buckets, and any other material that might come in contact with pus should be disinfected or disposed of and not shared with other horses.

Treatment involves lancing and draining the absecesses and, in some cases, antibiotics. An ultrasound can help to locate deep internal abscesses and find the best place to drain them.
Ruminants, such as sheep, goats and cattle can also become infected by this bacteria. Vaccines are available for sheep and goats, but there is no vaccine for horses. Pigeon fever is difficult to manage, as it is transmitted so easily and can linger in the horse's system, undetected, for months.

Yikes! What is really worrying me is that dear Peaches has a nasty cut on her face. It's healing but the process is slow.
