Misleading medical information will be conveyed if extended-spectrum beta-lactamase producers are resported as sensitive when they are actually resistant. Strains of K. pneumoniae and E. coli and a few other genera of the family enterobacteriaceae that produce ESBLs may clinically be resistant to therapy with penicillins, cephalosporins, or aztreonam, despite apparent in vitro susceptibility to some of these agents if only routine susceptibility testing is performed.
