What diseases do bullfrogs carry?

Bullfrogs can carry various diseases and parasites that may affect other amphibians and even humans. Notably, they can harbor the chytrid fungus, which is responsible for significant declines in amphibian populations worldwide. Additionally, they may carry the Asian amphibian chytrid pathogen, as well as parasites like the trematode Ribeiroia ondatrae, which can cause deformities in other amphibians. While bullfrogs themselves are generally resilient, their role as carriers can pose risks to biodiversity and ecosystem health.
