LOUISVILLE, Ky. (AP) — A disease responsible for killing millions of bats in North America has spread to caves at two state parks in eastern Kentucky that are homes to federally endangered bats, parks officials said Friday.

White-nose syndrome has been detected in caves at Carter Caves State Resort Park and Kingdom Come State Park, said state parks department spokesman Gil Lawson. Small numbers of bats have died so far from the disease, he said.
