Analysis of Archival Specimens Confirms White-Nose Syndrome in Little Brown Bats (Myotis lucifugus) from New York, USA, in Spring 2007.

White-nose syndrome (WNS), an emerging fungal disease of North American bats, was first diagnosed in January 2008, although mortality and photodocumentation suggest the disease might have been present earlier. Using archived samples, we describe a definitive case of WNS in little brown bats (Myotis lucifugus) from New York, US, in spring 2007.
