The disease is suspected when relentless itching (pruritus), excessive salivation, and sudden death are observed, especially when exposure to feral swine has occurred. Ingestion is the most common route, but transmission can also occur via inhalation or minor wounds. Dogs become infected after direct or indirect contact with infected swine infected dogs do not shed enough virus to transmit to other dogs. Even though PRV is prevalent in feral swine, most dog owners, veterinarians, hunters, and wildlife biologists are unaware of the risk. Prior to elimination of the disease in commercial swine, infection in dogs ( Canis lupus familaris) was commonly reported. commercial swine in 2004, the disease is still endemic in feral swine, thus posing a threat to the industry’s disease-free status, and potentially causing substantial economic losses. with a widespread geographic range extending across the country. įeral swine ( Sus scrofa) are an invasive species in the U.S. The virus can also establish latency in swine with reactivation occurring after natural stimuli, or as a result of stressors. Adult swine usually recover after infection, but high mortality rates in piglets, and abortions in pregnant sows are typical. Though swine (i.e., suids) are the only known reservoirs or natural hosts of the disease, numerous mammals, with the exception of humans, are susceptible to infection. Pseudorabies (PRV), also referred to as Aujeszky’s disease, is a viral disease caused by Suid alphaherpesvirus 1. Conclusionsĭogs that are used for hunting feral swine are at high risk of exposure to pseudorabies because the disease is considered endemic in feral swine in the U.S. The antibody prevalence of feral swine in the two states where the dogs were exposed is also examined. The second case occurred in multiple dogs in Arkansas after hunting feral swine, and subsequent consumption of the offal. The first case occurred in a dog in Alabama after participation in a competitive wild hog rodeo. The following report describes the progression of pseudorabies infection in dogs in two states after exposure to feral swine. Since dogs are commonly used for hunting feral swine, they are at high risk of exposure. Infected feral swine pose a threat to the disease-free status of the commercial swine industry, and to other animals, including dogs, that come in direct or indirect contact with them. commercial swine in 2004, though the virus remains endemic in feral swine. The risk to susceptible mammals was assumed to decrease when PRV was eliminated from U.S. Infection in mammals, with the exception of humans, typically causes extreme itching, facial swelling, and excessive salivation, followed by death in non-suid species. Pigs ( Sus scrofa) are the natural hosts of pseudorabies virus (PRV), also known as Aujeszky’s disease.
