Abstract: The sensitivity of NG-test CTX-M Multi assay and BL-RED test incubated 10 min for the detection of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae was 80.6% and 90.3% respectively. Using an extended 60 min incubation with the BL-RED test, its sensitivity was increased to 100% and 60.9% for ESBL-producing and cephalosporinase-overexpressing Enterobacteriaceae respectively.<br />Competing Interests: Declaration of Competing Interest None concerning the subject of this study.<br /> (Copyright © 2022 Elsevier B.V.
