The Kentucky State Veterinarian's office reported that results of testing performed and reported today by the University of Kentucky Veterinary Diagnostic Laboratory has confirmed a diagnosis of West Nile virus (WNV) affecting a second Kentucky horse in 2017.
The confirmation of West Nile virus is based on detectable WNv specific IgM antibody with compatible clinical symptoms demonstrated.
The 18-year-old female Tennessee Walking Horse was located in Franklin County. She is alive at this point.
She presented with clinical signs on July 24. She showed muscle fasciculation (predominantly on and above both front shoulders), mild lip paresis, inappetence and reluctance to move. She had no history of West Nile virus vaccination.
As of July 27 the mare was described as being in stable condition with some improvement noted.
