Ranavirus has caused disease epidemics and mass mortality events globally in free-ranging fish, amphibian, and reptile populations. Viral isolation and conventional PCR are the most common methods for diagnosis. In this study, a quantitative real-time PCR (qPCR) assay was developed using a TaqMan probe-based assay targeting a highly conserved region of the major capsid protein of frog virus 3-like virus (FV3-like) (Family Iridoviridae, genera Ranavirus). Standard curves were generated from a viral DNA segment cloned within a plasmid. The assay detected viral DNA 1000 times lower than conventional PCR. Thirty-one clinical samples (whole blood and oral swabs) from box turtles were tested using these assays and the prevalence of the virus determined. Quantitative PCR allows for a superior, rapid, sensitive, and quantitative method for detecting FV3-like virus in box turtles, and this assay will be useful for early detection and disease monitoring.
