Chytridiomycosis caused by chytrid fungus has driven numerous amphibian extinctions and affects the welfare of wild populations globally. Disease management is a growing conservation and welfare priority.
Chytridiomycosis causes prolonged suffering in affected amphibians as the progressive skin disease disrupts the physiological functions these animals depend on. The disease has driven some of the most dramatic wildlife population collapses ever recorded, with welfare harm compounded by conservation significance. Active disease management through probiotic treatments, habitat management, and captive breeding insurance populations represents the current best available welfare response. The global scale of the amphibian chytrid crisis means that addressing it requires international coordination of research, captive breeding capacity, and habitat protection.
