White Nose Syndrome (WNS) is a rapidly spreading fungal infection responsible for killing millions of bats within the past 9 years."Geomyces-destructans" is the causative fungal agent of the characteristic skin lesions seen on the exposed skin, particularly on wings and nose, and in the hair follicles of affected bats. WNS has only recently been discovered, in Howe's Cave, New York during the winter of 2006-2007, but affects 25% of the hibernating species. Six species of bats have been fatally effected by this panzootic; big brown bat, small-footed bat, little brown bat, northern long-eared bat, Indiana bat, and tricolored bat, and current bat population surveys suggest a 2-year population decline in excess of 75%. The geographical range of WNS has spread throughout 33 states, and 4 Canadian provinces.
