A fungal disease called ophidiomycosis is spreading among wild snakes around the world. This disease is caused by a fungus that interacts with the natural bacteria living on snake skin and with oils naturally produced by the skin. Certain helpful bacteria on snake skin can fight off the fungus by producing special compounds, but when the fungus takes over, it damages these protective bacteria, leading to worse infection. Understanding these interactions could help develop new ways to protect snakes from this emerging disease.
