Abstract
Diagnostic algorithms in commonly used automated bacterial identification systems fail to reliably identify a metallo-beta-lactamase in the Enterobacteriaceae. Misidentification as an extended-spectrum beta-lactamase may result in inappropriate dismissal of drugs such as aztreonam in favor of carbapenems, which may in turn select for a highly carabapenem resistant phenotype.Keywords
