First Report of Ophidiomycosis in a Free-Ranging California Kingsnake (Lampropeltis californiae) in California, USA.

Ophidiomycosis (snake fungal disease) is an emerging threat to snake health worldwide. We report a case of disseminated ophidiomycosis in a California kingsnake (Lampropeltis californiae) from Plymouth, Amador County, California, US, which is the first report of the disease in this species and in a free-ranging snake in California.
