A reliable phenotypic assay for detection of ESBLs and AmpCs in MBL-producing gram-negative bacteria with the use of aminophenylboronic acid, dipicolinic acid and cloxacillin.

Abstract excerpt

ESBLs and AmpCs may escape detection when they coexist with metallo-β-lactamases such as New Delhi Metallo-β-lactamases-1. In this study a combination disk assay was established using cefotaxime, cefotaxime/clavulanic acid, cefotaxime/clavulanic acid/cloxacillin, cefoxitin and cefoxitin/phenylbor...
