Health Issues Which May Affect This Animal

What Causes This Disease?

Chytridiomycosis is caused by a fungus, Batrachochytrium dendrobatidis, which seems to be specific to amphibians.

Where Is The Disease Found?

Chytridiomycosis is found throughout most of North America. It has been documented in a variety of amphibian species in Idaho.

Signs of Disease

Chytridiomycosis usually presents as a high mortality event in affected bodies of water. The fungus usually affects the skin and causes water balance problems. Adult amphibians infected with chytrid fungi have exhibited symptoms such as extended back legs, lethargy, and loss of the righting reflex. In larvae, jaw sheaths and tooth rows of tadpoles lack pigment or appear deformed, which may impede feeding activity. Chytrid can affect growth of juvenile amphibians and cause stunting or limb or mouthpart deformities.
