Description : For overnight detection of Gram-negative bacteria producing Extended Spectrum Beta-Lactamase MEDIUM PERFORMANCE CHROMagarTM ESBL allows the detection of ESBL-producing bacteria while inhibiting the growth of other bacteria, including most of those carrying AmpC type resistance. This is an important feature because intrinsic AmpC resistance has less epidemic relevance, but often leads to ESBL false positive reading in the classical testing methods. Detection of resistant isolates is diff
