Nonclostridial gas gangrene due to Streptococcus anginosus in a diabetic patient

Streptococcus anginosus was recently identified as a distinct species from the other members of Streptococcus milleri group (Streptococcus constellatu s, Streptococcus intermedius). We report a rare case of nonclostridial gas gangrene caused by S anginosus. A 62-year-old diabetic woman was admitted w ith gas gangrene of the perineal area. She had been taking her oral hypogly cemia medication regularly for 10 years, but the diabetes was inadequately controlled. She was treated with surgical debridement of the necrotic tissu e, insulin injection, and antibiotic therapy, and had a satisfactory clinic al course.
