A fungus that has killed about 6 million bats in North America and Canada has been found for the first time in Kentucky's Mammoth Cave National Park, federal authorities said.
White-nose syndrome has been confirmed in nine national parks and 19 states as far west as Missouri.
A bat killed by the fungus was found in Long Cave, an undeveloped cave about 1.3 miles long, not connected to Mammoth Cave.
The park service will continue giving tours of Mammoth Cave. To prevent spread of the disease, the parks service screens all visitors before they go on a tour and has them walk across decontamination mats as they exit.
