title: [Detection methods for drug-resistant bacteria in routine examination--ESBL].
abstract: Extended-spectrum beta-lactamases(ESBLs) confer resistance to cefotaxime, ceftazidime, aztreonam, extended-spectrum penicillins, and structurally related beta-lactams in clinical isolates of K. pneumoniae and E. coli. Some ESBLs, however, show a lower level of resistance and these isolates may not reach NCCLS breakpoints for resistance. Optimal methods for confirmation of ESBL-producing isolates are described.
