ABSTRACT
The aim of this study was to evaluate the performances of MicroScan (Siemens Healthcare, USA) and Phoenix (Becton Dickinson Diagnostic Systems, USA) automated systems for the detection of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae. ESBL-producers were detected from 18 E. coli strains and 26 K. pneumoniae strains using MicroScan, Phoenix, and double-disk synergy test (DDST). The ESBL types were determined by PCR direct sequencing. ESBL genes were detected in 38 (86.4%) of the 44 test strains. The sensitivities of MicroScan, Phoenix, and DDST were 94.6%, 79%, and 89.5%, respectively. Both MicroScan and Phoenix provided acceptable results for the examination of clinical isolates.
