Amphibian chytrid is a disease that infects the skin of amphibians, a vital organ through which many drink and breathe. It was discovered a decade ago; dozens of frog species have already vanished because of it. In environments where it thrives, the fungus can kill 80 percent of the native amphibians within months. Currently, it is unstoppable and untreatable in the wild, even in ‘protected’ areas. Amphibian chytrid is believed to have originated in Africa. The export of African clawed frogs (likely resistant carriers of the fungus) around the world for human pregnancy testing and lab studies spread this disease worldwide. Recently, the food and pet trades may have contributed to the problem as well. The chytrid’s spread and effects may be exacerbated by climate change – warmer temperatures dry the moist areas where amphibians live, causing stress that may lead to greater susceptibility to the disease.
