Phenotypic and genotypic characterizations of extended-spectrum beta-lactamase-producing in Thailand.

Purpose: Extended-spectrum β-lactamases (ESBLs) have become an issue in community worldwide due to an increase in antibiotic resistance over the past decade. This study was aimed to investigate the phenotypic and genotypic characteristics of ESBL-producing in Thailand.

Materials And Methods: In this study, all clinical isolates collected from tertiary hospitals in Thailand were identified as by biochemical tests and MALDI-TOF mass spectrometry.
