A disease that some scientists have compared to the illness killing bats by the millions has been documented in a wild snake in Georgia. An emaciated mud snake from Bulloch County tested positive last month for Snake Fungal Disease, according to the Southeastern Cooperative Wildlife Disease Study. The mud snake is the first free-ranging snake from Georgia that the Athens-based cooperative has confirmed with Ophidiomyces ophiodiicola, the fungus associated with the disease.
