Survey of Aquatic Turtles on the Savannah River Site, South Carolina, USA, for Prevalence of Ranavirus

摘要

Ranaviruses have the ability to infect amphibians, fish, and reptiles, and they have caused multiple amphibian die-off events in the US and Europe. Their prevalence in amphibian populations is much more commonly studied than in chelonian populations. We examined blood samples (n=286) from eight aquatic turtle species collected during 2008-14 on the Savannah River Site, South Carolina, US, as part of long-term mark-recapture efforts. Previous studies in the southeastern US found high prevalence of Ranavirus in amphibians, but we did not detect Ranavirus in any of the turtles sampled, suggesting the absence of the virus or its presence at a very low prevalence in aquatic turtles across the Savannah River Site during the years tested.
