The Relationship Between Antecedent Antibiotic Use and Resistance to Extended-Spectrum Cephalosporins in Group I -Lactamase-Producing Organisms
1 Nov 1995
Abstract excerpt
Gram-negative pathogens are increasingly resistant to extended-spectrum cephalosporins (ESCs). Using a prospective, case-controlled observational study, we examined the prevalence and the risk factors for development of resistance to ESCs in group I beta-lactamase-producing organisms. Of the 386 isolates of Enterobacter species, Pseudomonas aeruginosa, Citrobacter species, and Serratia marsescens from 340...
