This document describes an outbreak of Ranavirus, Herpesvirus, and Mycoplasma infection in a captive population of 22 Eastern Box Turtles. The outbreak was first detected in July 2011, when several turtles were found dead or moribund. Living turtles were quarantined and treated with antibiotics, antivirals, fluids, and nutrition. Molecular monitoring found high prevalence of Ranavirus shedding that decreased with treatment. After 5 months of follow up, all surviving turtles were virus-free. The intensive intervention improved survival compared to previous reports, though co-infection did not affect outcomes. Further study of antivirals and immune response is warranted.
