Chytrid fungus found on amphibians in Oklahoma

-

SHARE


The Herpetology Department of the Sam Noble Museum was funded through grants from the Oklahoma Department of Wildlife Conservation (ODWC) and Oklahoma City Zoo Conservation Action Now (CAN) to determine the presence and prevalence of the amphibian infectious disease Batrachochytrium dendrobatidis (also know as Bd or chytrid) in Oklahoma. This project will be ongoing for three years and covers field research in multiple areas of the state. In 2015, our field sampling efforts were focused on central and southeastern Oklahoma. Members of the Siler Lab spent August–October extracting DNA from swabs that had been rubbed along the exterior of live amphibian bodies. Currently, our collaborating lab at the University of South Dakota is screening our samples for Bd. Preliminary results suggest that Bd is more common in Oklahoma than previously thought.
