Abstract:
Batrachochytrium salamandrivorans (Bsal) is a recently discovered fungal pathogen that has caused declines of wild Fire Salamander (Salamandra salamandra) populations across Europe. Risk models based on environmental suitability suggest that Bsal poses high risk to North American amphibian biodiversity, especially in the southeastern and northwestern USA. Our goal was to estimate the susceptibility of 29 North American amphibian species to Bsal infection and chytridiomycosis. Experimental animals were exposed to one of four Bsal zoospore doses (103-6), and their condition monitored for at least six weeks. We swabbed animals every six days to estimate Bsal infection intensity.
