Athlete’s foot therapy tapped to treat bat-killing fungus
Over the past four years, a mysterious white-nose fungus has struck hibernating North American bats. Populations in affected caves and mines can experience death rates of more than 80 percent over a winter. In desperation, an informal interagency task force of scientists from state and federal agencies has just launched an experimental program to fight the plague. Their weapon: a drug ordinarily used to treat athlete’s foot.
