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. 1098-660X 10.1128 /JCM.03614-13 https://hdl.handle.net/20.500.14352/35279 http://dx.doi.org/10.1128 /JCM.03614-13 Rapid detection of β-lactamase-hydrolyzing extended-spectrum cephalosporins in Enterobacteriaceae by use of the new chromogenic βLacta test
