title: [Study of in vitro activity of 3 cephalosporins and their combination with 2 beta-lactamase inhibitors against 4 enterobacteria strains producing extended spectrum beta-lactamase].
abstract: The in vitro antibacterial activity of cefotaxime, cefepime and cefpirome was evaluated alone and in association with two beta-lactamase inhibitors: clavulanic acid and sulbactam against 65 extended broad spectrum beta-lactamase producing enterobacteriaceae strains [Klebsiella pneumoniae (35), Proteus mirabilis (9), Escherichia coli (11), Enterobacter aerogenes (10)]. The lowest MICs were observed for cefepime and cefpirome used alone. In association with inhibitors cefotaxime was less effective against E. aerogenes. Most isolates of K. pneumoniae, P. mirabilis, E. coli were susceptible to all the different tested associations.
