MICRONAUT-S Carbapenemases
2-test plate MICRONAUT-S Carbapenemases Detection system
Phenotypic confirmation of KPC, MBL as well as OXA-48-like type D carbapenemases in Enterobacterales. The new inhibitor combination meropenem-avibactam and determination of high-level temocillin resistance improves phenotypic detection of OXA-48-like enzymes in enterobacteria.
By selection of the concentration ranges of meropenem as mono compound (0.06 – 128 mg/L) and the inhibitor combinations meropenem-3-amino-phenyl-borate (3-APB), meropenem-EDTA and meropenem-avibactam (each 0.031 – 32 mg/ml), the detection of type A carbapenemases (e.g. KPC), metallo-β-lactamases and OXA-48-like type D carbapenemases is possible when the meropenem screening cut-off concentration for enterobacteria is exceeded1.
1EUCAST guidelines for detection of resistance mechanisms and specific resistances of clinical and/or epidemiological importance. EUCAST Version 2.0, July 2017.
MICRONAUT-S ß-Lactamases
- MIC determination of antibiotics and antibiotic combinations against all relevant gram-negative bacteria (Enterobacterales, Aeromonadaceae, Pseudomonadaceae etc.)
- ESBL: 3 extended spectrum cephalosporins and their combination with clavulanic acid
- Amp-C: 3 extended spectrum cephalosporins and their combination with 3-Amino-Phenyl-Borate (3-APB)
- KPC: MIC determination of meropenem as a mono substance and in combination with 3-Amino-Phenyl-Borate (3-APB)
- MBL: MIC determination of meropenem as a mono compound and in combination with the divalent cationic chelator EDTA
- OXA-48-like type D-carbapenemases based on determination of high-level temocillin resistance
- Low-level carbapenem resistance based on introduction of ertapenem / meropenem screening cut-off value according to EUCAST
