%X The chromogenic βLacta test developed for the rapid detection of β-lactamase-hydrolyzing extended-spectrum cephalosporins in Enterobacteriaceae revealed good performance with extended-spectrum β-lactamase (ESBL) producers (97.5% true-positive results). However, false-negative results occurred with chromosomal AmpC hyperproducers and plasmid AmpC producers, whereas uninterpretable results were mostly due to VIM-1 carbapenemase producers and possibly low levels of expressed ESBLs.
