“Ranaviruses infect mountain yellow-legged frogs (Rana muscosa and Rana sierrae) threatened by Batrachochytrium dendrobatidis” by Tom, Roland, and Angela Picco (United States Fish and Wildlife Service) appears in Herpetological Conservation and Biology. The paper (available here) documents the presence of a ranavirus in a small number of mountain yellow-legged frog populations. Despite causing occasional tadpole mortality events, ranaviruses play a small role in large scale mountain yellow-legged frog declines, especially when compared to the fungal pathogen Batrachochytrium dendrobatidis.
