Feral pig in Oregon, US, found infected with pseudorabies



A feral pig in the Central Oregon, the United States, has been found infected with pseudorabies, a contagious disease that can harm livestock and spread to some wildlife species, state officials said on July 10.


The infection was discovered through a surveillance programme that started in 2007 in Oregon. This is the first positive case since the programme started.


"While the presence of PRV in Oregon has so far been an isolated event, it shows that our disease surveillance programme is working. It is too early to know how this disease appeared in Oregon, but additional testing and investigation are ongoing," said Ryan Scholz, a district veterinarian with Oregon Department of Agriculture (ODA), in a press release.


Pseudorabies is a contagious, infectious and communicable viral disease of livestock, causing neurologic, respiratory and reproductive disorders.


Although other livestock species have occasionally become infected, the pig is the only natural host of this disease, ODA reports. The disease was eradicated from the US commercial pig industry in 2004 but remains in some localised feral swine populations.


According to Scholz, no local livestock in Oregon have been reported to be exposed to  pseudorabies. The latest case is also not expected to affect Oregon's PRV-free status.
