Bactericidal in-vitro activity of beta-lactams and beta-lactamase inhibitors, alone or associated, against clinical strains of Acinetobacter baumannii: effect of combination with aminoglycosides.

Abstract excerpt

Five Acinetobacter baumannii strains of various phenotypes were selected on the basis of the results of a national survey in France in 1991. beta-Lactamases in Acinetobacter isolates were characterized by isoelectrofocusing. We carried out a 24 h time-kill study to assess the bactericidal effect of antibiotic alone or in combination against A. baumannii strains. The initial inoculum was 10(6) cfu/mL. Antibiotics...
