... Ranaviruses are emerging as serious pathogens across ectothermic taxa, recently causing mass die-offs including entire chelonian populations. Amphibians may serve as reservoirs for chelonian infections. To assess this idea and determine whether chelonians in the Midwest are infected with (or at risk for) ranavirus infections, we tested for presence of ranavirus infections among sympatric larval am ...

... The Maryland Zoo in Baltimore experienced an outbreak of Frog virus-3 (FV3)-like ranavirus during the summer of 2011, during which 14 of 27 (52%) of its captive eastern box turtles (Terrapene carolina carolina) survived. To assess survival, immunity, and viral shedding, an experimental challenge study was performed in which the surviving, previously infected turtles were reinfected with the outbre ...
... An eastern box turtle (Terrapene carolina) was found in a stream in the southeastern US, with a mass affecting the distal right forelimb. The turtle developed complications during hospitalization, including lethargy and oral caseous plaques and eventually died. Postmortem analyses diagnosed a mixed infection of phaeohyphomycosis and Ranavirus. ...
... Ranaviruses are a group of emerging infectious pathogens that threaten reptiles around the world; however, their geographic and taxonomic distribution in wild reptiles is understudied relative to amphibians. We sampled tissues from 2 reptile species: Terrapene Carolina carolina (Eastern Box Turtle) and Sceloporus undulatus (Eastern Fence Lizard) in central Virginia to determine if they carried the ...

Abstract:
... Mortality events in eastern box turtles (Terrapene carolina carolina) threaten conservation efforts across the species range. These events are often under-diagnosed and, when observed, predictive health factors are unavailable prior to death. At Kickapoo State Park in central Illinois, USA, ranaviruses caused observed mortality events in amphibians and chelonians in 2014 and 2015. Following these ...
