Chytridiomycosis (Amphibian chytrid fungus disease)

About the fact sheet

Chytridiomycosis is an infectious disease that affects amphibians worldwide. It is caused by the chytrid fungus (Batrachochytrium dendrobatidis), a fungus capable of causing sporadic deaths in some amphibian populations and 100 per cent mortality in others.

The disease has been implicated in the mass die-offs and species extinctions of frogs since the 1990s, but its origin and true impact on frog populations remains uncertain and continues to be investigated.
