Working to understand risk factors that could contribute to the emergence of the pathogen Batrachochytrium salamandrivorans (Bsal) in North America

Batrachochytrium salamandrivorans (Bsal) is a fungal pathogen that likely originated in Asia, where local species harbor infections without signs of clinical disease.

Bsal has recently been documented in Europe, where it is causing mass die-offs of some salamander species. It is hypothesized to have been introduced through unregulated international trade.

To date, Bsal has not been detected in amphibian populations in North America. However, North America is a global hotspot for salamander biodiversity, accounting for 50 percent of species worldwide, so there is substantial concern about the possibility of Bsal’s introduction to the continent.
