VS Reported in New Mexico Horse

A horse in De Baca County, N.M., is reported to be positive for vesicular stomatitis, according to a statement released by the Texas Animal Health Commission.

The premises has been under quarantine since June 18, 2009. No other horses are exhibiting signs of the disease. At this time there are no other investigations.

Vesicular stomatitis (VS) is a sporadically occurring virus that is endemic to the United States. It most recently occurred in 2006 in Wyoming. It primarily affects horses, cattle, and swine, but it can also affect sheep, goats, and deer. The disease causes blister-like lesions in the mouth and on the dental pad, tongue, lips, nostrils, hooves, prepuce, and teats of livestock. When the blisters break, they can leave painful raw areas that can precipitate lameness and a reluctance to eat.

This is the second positive horse reported this year. The other case occurred in a horse in Starr County, Texas. Read more. That case resulted in some additional transport restrictions on Texas livestock. Texas has now added additional requirements for animals entering the state from New Mexico (see the code).  

Livestock owners in New Mexico who think their animals might be infected should have them examined by a veterinarian. Vesicular stomatitis is on the list of reportable diseases and suspected cases should be immediately reported to the USDA and the N.M. Livestock Board.
