[Necrotizing fasciitis. A rapid fatal course of Streptococcus pyogenes, Lancefield group A serotype M1 (killer streptococci), infection].

The case history of necrotizing fasciitis in a previously healthy man aged 37 years is presented. The disease ran a rapidly fatal course. The only finding on bacterial culture was Streptococcus pyogenes, Lancefield group A, serotype M1, ("killer streptococci"). The therapeutic possibilities are briefly outlined and the importance of rapid surgical intervention is emphasized. It is concluded that this patient was actually beyond therapeutic aid less than 12 hours after admission. Necrotizing fasciitis caused by Streptococcus pyogenes, Lancefield group A, serotype M1, is comparable with meningococcal disease. It appears probable that the disease had developed in this patient as a sequel of streptococcal arthritis.
