Bacteriology of necrotizing fasciitis.

Sixteen patients with necrotizing fasciitis were observed under clinical and laboratory conditions for collection, preservation, and culture that permitted optimal retrieval of anaerobes. The clinical observations of necrosis of fascia, subcutaneous fat and skin with thrombosis of the microvasculature, and absence of myonecrosis were clearly apparent in these patients. Two clear-cut groups of culture and gram stain results were found, suggesting that the clinical entity of necrotizing fasciitis can occur after infection by different infecting organisms. The cultivation of Streptococcus pyogenes (group A), either alone or in combination with staphylococcus, in three patients conforms to the culture results found by Meleney [1] in his original description.
