Prevalence and quinolone resistance of fecal carriage of extended-spectrum beta-lactamase-producing Escherichia coli in 6 communities and 2 physical examination center populations in Shanghai, China

摘要

Objectives: To characterize extended-spectrum beta-lactamase (ESBL)-producing Escherichia colt isolates from the community, determine their antibiotic sensitivity profiles and quinolone resistance mechanisms, and identify any horizontal transfer of ESBL genes.
