During 2008, the ninth year of a long-term biologic monitoring program, 3 eastern massasauga rattlesnakes (Sistrurus catenatus catenatus) with severe facial swelling and disfiguration died within 3 weeks after discovery near Carlyle, Illinois, USA. In spring 2010, a similar syndrome was diagnosed in a fourth massasauga; this snake continues to be treated with thermal and nutritional support and antifungal therapy. A keratinophilic fungal infection caused by Chrysosporium sp. was diagnosed after physical examination, histopathologic analysis, and PCR in all 4 snakes. The prevalence of clinical signs consistent with Chrysosporium sp. infection during 2000–2007 was 0.0 and prevalence of Chrysosporium sp.–associated disease was 4.4% (95% confidence interval [CI] 1.113.2 for 2008 and 1.8% (95% CI 0.011.1 for 2010.
