The Sam Noble Museum Herpetology Department was recently funded by Oklahoma Department of Wildlife Conservation (ODWC) and Oklahoma City Zoo Conservation Action Now (CAN) to conduct Oklahoma statewide surveys to test for the presence and prevalence of the amphibian infectious disease Batrachochytrium dendrobatidis (also know as Bd or chytrid) over a three year period (2015-2017). Members of the Siler Lab spend August–October of each year extracting DNA from swabs that had been rubbed along the exterior of live amphibian bodies in the Spring of each year. You can also view our current chytrid results by Oklahoma county or a summary of both chytrid and ranavirus via the following infographic.
