Cephalosporins resistance is increasing in Escherichia coli in Spain. We characterize infections by E. coli with reduced susceptibility to third-generation cephalosporins (3GCs) with the AmpC phenotype. Between January 2004 and March 2007, 121 E. coli isolates with the AmpC phenotype were collected (4.8% of all the 2538 E. coli isolates with reduced susceptibility to 3GCs). These isolates were further...
