"Is the Fatal Amphibian Chytrid Fungus Spread via Pet Frogs?"

Researchers are studying whether the chytrid fungus -- which has decimated frog and salamander populations around the world -- is being spread among wild amphibians by the release of infected animals bought at pet stores. The fungus has devastated some 200 species globally, and may be responsible for the greatest known disease-caused loss of biodiversity in recorded history.
