Two cases of necrotizing fasciitis due to Acinetobacter baumannii.

Necrotizing fasciitis has conventionally been associated with the streptococci, and when it is caused by other organisms, it is most often the result of a polymicrobial infection. We report on two cases of fatal monomicrobial necrotizing fasciitis due to Acinetobacter baumannii, an unusual finding that may be an indication of enhanced virulence of the organism.
