beta-Lactamases involved in resistance to broad-spectrum cephalosporins in Escherichia coli and Klebsiella spp. clinical isolates collected between 1994 and 1996, in Barcelona (Spain)

Abstract excerpt

The aim of this study was to evaluate the incidence of decreased susceptibility to broad-spectrum cephalosporins in Enterobacteriaceae that lack inducible chromosomal bla genes, and to determine the enzymes responsible for resistance. From all clinically relevant Enterobacteriaceae strains isolated between 1994 and 1996, 88 of 7054 Escherichia coli, seven of 581 Klebsiella pneumoniae and 23 of 166 Klebsiella...
