Chytridiomycosis, caused by the fungal pathogen Batrachochytrium dendrobatidis, has driven over 90 amphibian species to extinction and threatens hundreds more. The disease causes suffering and death on an enormous scale.
The suffering caused by chytridiomycosis is immense in both scope and intensity. Infected amphibians experience progressive debilitation as fungal growth prevents skin respiration and electrolyte regulation, leading to seizures and cardiac failure over days to weeks. Given that many amphibian species possess nociception and stress response systems, this disease likely causes significant suffering. Beyond individual welfare, the ecological collapse of amphibian populations disrupts food webs, insect population control, and nutrient cycling. Biosecurity failures in the international wildlife trade represent the primary driver of disease spread, making regulatory intervention critical.
