Field Reports: Oregon wolf dies from parvovirus

 The first case of parvovirus in Oregon wolves has been documented by the Oregon State University Veterinary Diagnostic Lab.

The wolf known as OR19, found dead by Oregon Department of Fish and Wildlife biologists on May 19, died of complications of canine parvovirus, according to the lab's preliminary report.

The disease is contagious in canids and usually fatal. Domestic dogs usually are protected by vaccinations, but parvo has been found in wolf populations throughout the West, causing short-term wolf declines, state officials said.
