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 photo-documentation suggest the disease may have been present earlier. Using archived samples, we describe a definitive case of WNS in little brown bats (Myotis lucifugus) from New York, USA, in spring 2007.
