A fungus known as Geomyces destructans is indeed responsible for the dusting of white across bat noses and wings that has wiped out entire populations of the flying mammals, new research shows. By purposefully infecting healthy bats with the fungus--and confirming that seemingly healthy "control" bats from the same population did not get sick from a prior but hidden fungal infection--microbiologist David Blehert of the U.S. Geological Survey and his colleagues showed in a paper published online October 26 in Nature that G. destructans is in fact responsible for the disease known as white-nose syndrome (WNS), which has devastated bat populations across the northeastern U.S., killing an estimated one million of the animals.
