The first positive case of an equine contracting West Nile virus (WNV) was confirmed last week at the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL). The horse is from Limestone County. This follows a year where WNV cases were confirmed from the Gulf Coast to the Panhandle.
In 2015, the Texas A&M Veterinary Medical Diagnostic Laboratory (TVMDL) confirmed 40 Texas horses infected with West Nile virus (WNV) and six cases of Eastern Equine Encephalitis (EEE). The positive cases were found from the Panhandle to Dallas, to South Texas and the Houston area. The most prolific area with positive cases was the southeastern region of the state. The common factor in each case was confirmation from the owner or veterinarian that the horse had not been vaccinated for these common neurologic diseases.
Vaccination for WNV and other neurologic diseases like Eastern and Western Equine Encephalitis is recommended. Additionally, Equine Herpesvirus-1 cases have been confirmed in several states in 2016; this neurologic disease has similar clinical signs as those diseases stated above.
TVMDL offers veterinarians diagnostic testing options to aid in diagnosing a horse that exhibits neurologic clinical signs.
- Equine Encephalitis Panel (WNV,EEE,WEE IgM-capture ELISA)
- West Nile Virus (qPCR or IgM Capture ELISA)
- Eastern Equine Encephalitis IgM (ELISA)
- Western Equine Encephalitis (VN or IgM ELISA)
- Equine Herpesvirus-1 (qPCR)
