[Necrotizing soft tissue infections: role of the localization for the antibiotic management].

Necrotizing soft tissue infections (NSTI) are infrequent but life-threatening, and require prompt empirical antibiotic therapy. Current nosologic classifications have limited value because the criteria used are imprecise and their bacteriological specificity is uncertain. The aim of this study was to describe the bacterial flora and its antibiotic sensitivity in a cohort of patients with NSTI, and to derive guidelines for the choice of antimicrobial chemotherapy.
