[RC] New Vesicular Stomatitis case - Patti Kuvik

Just got this - if you're travelling from, to or through NM, it may be
worthwhile to check with your home or destination State Vet for any
restrictions. (Last year's restrictions also applied to horses from states
bordering VS case states.)

Emergency Management Warning 1: Positive Case of Vesicular Stomatitis in
Horses in the State of New Mexico

On 27 Apr 2005, the National Veterinary Services Laboratories (NVSL) in
Ames, IA, confirmed the finding of vesicular stomatitis virus (VSV) in
horses at one premises in Grant County, New Mexico.  This is the 1st
confirmed case of vesicular stomatitis in the United States in 2005.

Vesicular stomatitis is a viral disease which primarily affects horses,
cattle, and swine.  The agent that causes vesicular stomatitis, VSV, has a
wide host range and can occasionally infect sheep and goats.  In affected
livestock, VSV causes blister-like lesions to form in the mouth and on the
dental pad, tongue, lips, nostrils, hooves, and teats.  These blisters
swell and break, leaving raw tissue that is so painful that infected
animals generally refuse to eat and drink and show signs of lameness.
Severe weight loss usually follows, and in dairy cows a severe drop in milk
production commonly occurs.  Affected dairy cattle can appear to be normal
and will continue to eat about half of their feed intake.

The affected premises has 6 horses and approximately 110 head of cattle.
Only 2 horses are known to have clinical signs and none of the cattle are
showing clinical signs. All animals susceptible to vesicular stomatitis are
being held on the premises.

Laboratory results showed that both ill horses were positive on the
complement fixation (CF) test and virus isolation was achieved from 1
horse. The isolate is the New Jersey strain of VSV.

The last case of vesicular stomatitis in the United States was confirmed in
the State of Colorado in December 2004.

APHIS Veterinary Services and the New Mexico Livestock Board will continue
to monitor the situation and conduct response activities in an effort to
minimize trade restrictions.

Please forward this information to your federal, State, and industry
counterparts as necessary.
