(Thanks to Elizabeth for calling my attention to this story.)
Bd causes devastating chytrid disease, first identified about a decade ago. In the past few years, a number of studies have shown that it is an important factor in the recent drop-off in amphibian numbers. Worldwide, chytrid disease has caused extinctions and declines in 200 species of frogs. Ranaviruses also cause large die-offs, but scientists do not yet know whether they can contribute to extinctions.
