Spread of Amphibian Diseases (Image 2)

July 27, 2010
Infectious diseases are affecting populations of amphibians, from frogs to salamanders. Salamanders in bait shops in Arizona, Colorado and New Mexico are infected with ranaviruses, and those in Arizona with a chytrid fungus called Batrachochytrium dendrobatidis (Bd). The commercial amphibian bait trade may be a source of 'pathogen pollution.' Pathogens are disease-causing agents such as some viruses and bacteria.
