Avian influenza, rabies, mad cow disease, and even chronic wasting disease are animal diseases that make the headlines because of their threat to human health, and the ease in which they spread among animals, regions – even countries. But nongame wildlife diseases are less known.
Although an alert for global amphibian declines began almost 30 years ago, it took another decade for ecologists to realize that diseases were a top threat to amphibians.
Today, the groundwork laid by studying earlier threats may make a difference for hundreds of North American amphibians that could be in danger from an exotic pathogen that is hitchhiking along global trade routes, and may soon appear on this continent.

Did you know: Bsal and other exotic infections or diseases are most likely to be introduced to a new ecosystem via an infected amphibian or carrier imported as a pet. You can help prevent exotic diseases from spreading by ensuring you purchase pets only from reputable breeders or suppliers, and that they raise only certified disease-free, legally-imported animals.
