(Salem, OR) -- A deadly fungus to bats has been found in seven dead bats in Oregon. White-nose syndrome was found in bat guano last year at a roost in Clatsop County. The National Wildlife Health Center has confirmed the disease was found in six Yuma myotis bats in Columbia County and one little brown myotis bat in Benton County. They were all found dead in residential areas. The fungus grows on the bat's skin causing irritation. When they're supposed to be hibernating, they frequently wake up to groom off the fungus and that uses up critical energy they need for hibernation.
