An Martel of Ghent University in Belgium and her colleagues first discovered Bs when analyzing samples from salamanders that had died a week after infection. To understand the potential impact this fungus could have on amphibians globally, the researchers experimentally infected 35 species, including frogs, toads, caecilians, salamanders, and newts. The infection was lethal to most of the European salamander species tested, but frogs and toads showed no signs of the fungus.
