The virus was identified in dead largemouth bass collected by the Wisconsin Department of Natural Resources (DNR) during an investigation into a May 2015 fish kill in Pine Lake.Scientists at the U.S. Fish and Wildlife Service’s La Crosse Fish Health Center isolated the previously unknown virus, sending it to a “virus-hunting laboratory” operated by Tony Goldberg in the Department of Pathobiological Sciences at the University of Wisconsin-Madison’s School of Veterinary Medicine, reports Science News Line.There, the virus’ genome was broken down using “next generation sequencing” technologies and the hunt began. Goldberg and his colleagues scoured the genetic databases, looking to see if the virus was known or something unique and new. Goldberg says the virus is indeed, new to science. It has been dubbed largemouth bass reovirus (LMBRV).
