It is only recently that GGS infections have been reported in the literature. These infections are rare, but they are serious when they occur. The organism is not very virulent, and serious infections occur only in patients who are immunocompromised, have some serious underlying disease such as cancer or intravenous drug abuse, or are at the extremes of age. I have described a fatal case of GGS meningitis and endocarditis in a previously healthy 84-year-old who had obtundation, irritability, and cellulitis. Many of the separately reported characteristics of serious GGS infections were present together in this case.
