　　VOICE ONE:

　　Cases of white nose syndrome have been confirmed in New York, New Jersey, Connecticut, Vermont, Massachusetts and Pennsylvania. It is difficult for scientists to know the exact number of bats that have died as a result of white nose syndrome. However, some estimate that hundreds of thousands of bats have already disappeared.

　　The United States Geological Survey says the disease has affected six bat species. They include little brown bats, northern bats, tricolored bats, Indiana bats, small-footed myotis and big brown bats.

　　Biologists are currently studying possible ways to keep the disease from spreading. Tests are needed to guarantee a plan that will be effective.
