Bd can spread rapidly through amphibian populations and has been blamed for numerous extinctions around the globe. The mechanism by which the fungus killed these animals, however, was unknown. Histological preparations of the skin of infected frogs showed clear signs of infection, but other known cutaneous infections are...
