  1. Emergence of antimicrobial resistance in gram-negative bacilli causing bacteremia during therapy.

    Article - En anglais

    Treatment of serious infections caused by gram-negative bacilli with beta-lactam antimicrobial agents can induce Class I beta-lactamase production.

    This phenomenon can result in resistant microorganisms, and has been postulated to be a cause of therapeutic failure.

    The charts of patients bacteremic with Pseudomonas aeruginosa, Serralia marcescens, Enterobacter cloacae, Citrobacter freundii, Proteus vulgaris, and Providencia species (n=120) during a 3-year period were reviewed to determine how common the emergence of resistance was, and to determine if in vitro susceptibility testing was a reliable therapeutic guide.

    Emergence of resistance was believed to occur when a subsequent bacteremic isolate showed at least a fourfold increase in minimum inhibitory concentration accompanied by a change of interpretive susceptibility category.
