The curious case of the expiring bats is one step closer to a solution, thanks to work done by UW–Madison researchers. For several years, scientists were baffled by falling bat populations in North America, as the flying mammals died due to a mysterious ailment called white-nose syndrome. But a team led by School of Veterinary Medicine honorary fellow David Blehert has proven that the animals are victims of a fungus called Geomyces destructans. In a controlled study, the group took several dozen little brown bats and divided them into three groups. The first had no contact with G. destructans; the second was infected with the fungus; and the third was not infected directly but was exposed to the bats that had the fungus. By the end of the study, the bats in the first group remained healthy, while nearly all the bats in the other two groups showed signs of white-nose syndrome. But the mystery isn’t completely solved, notes Jeff Lorch ’05, PhDx’12, lead author of the study. G. destructans is widespread in Europe, yet doesn’t seem to be killing bats there. “We can now continue to look at both the fungus and North American bats to try to find out what about the fungus makes it so deadly here,” he says.
