Disease

Chytridiomycosis


What is chytrid?

Chytridiomycosis is a disease caused by the fungus Batrachochytrium dendrobatidis, sometimes called Bd, the chytrid fungus or just chytrid.

The disease is thought to be a major factor in the decline and extinction of many amphibian species across the world, particularly in Australia, the Caribbean and North, Central and South America.

It is thought it affects the animals skin tissue and causes problems with respiration and water uptake. As the fungus only affects keratinised tissue it does not cause the death of tadpoles - they only have keratin in their mouthparts and so carry the disease until they metamorphose.

In the UK, toads appear more susceptible than other amphibian species. The disease has had a lot of press coverage which is excellent for raising awareness but it is important to stress that if you are finding dead amphibians it is far more likely there is another cause.
