Long-term Carriage of Extended-Spectrum β-Lactamase–Producing Escherichia coli and Klebsiella pneumoniae in the General Population in The Netherlands

摘要

Extended-spectrum and plasmid-encoded AmpC β-lactamase–producing (ESBL/pAmpC) Escherichia coli and Klebsiella pneumoniae carriage persisted for >8 months in one-third of participants. Carriage of E. coli belonging to phylogenetic group B2 and D and travel to ESBL high-prevalence countries were associated with prolonged carriage.
