CWHL undergraduate researcher, Dante Napoletano, is revisiting archival samples from a diamondback terrapin (Malaclemys terrapin) die-off in 2015 associated with saxitoxin. During the original diagnostic investigation of the die-off, preliminary evidence of herpesvirus was found in a handful of tested animals. Now, he is working to clarify whether these samples truly have herpesvirus and characterize the specific virus if it is found. While herpesvirus would be a secondary finding to the primary toxicant cause of the die-off, this work can help us better understand the diverse threats to our marine turtle populations.
