The coordinated global response to chytrid fungus combines captive insurance populations, probiotic research, and habitat management to address the world's worst wildlife disease.
Individual amphibians infected with chytrid suffer from electrolyte imbalance causing heart failure - a distressing death. The scale of mortality is staggering: billions of individual amphibians have died from chytrid globally. Probiotic treatment programs that help surviving populations develop resistance represent a welfare advance - preventing the disease rather than treating affected individuals. Captive breeding programs must maintain natural behaviors and appropriate environmental complexity for amphibians to remain physically and psychologically healthy.
