An evaluation of screening methods for the detection of extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella pneumoniae in environmental samples from healthcare settings

Esther Picton-Barlow, Claudia McKeown, Sally Forrest…·Fabrice E. Graf

This study evaluates screening methods to detect ESBL-producing E. coli and K. pneumoniae in healthcare environmental samples, finding that 18-hour pre-enrichment and specific selective agar improve detection.
