CHROMagar™ mSuperCARBA™


CHROMagar has launched a brand new medium for the detection of gram-negative bacteria with a reduced susceptibility to most of the carbapenem agents.  

Short Background
CDC: «Carbapenem-resistant Enterobacteriaceae (CRE) are usually resistant to all β-lactam agents as well as most other classes of antimicrobial agents. The treatment options for patients infected with CRE are very limited. Healthcare-associated outbreaks of CRE have been reported. Patients colonized with CRE are thought to be a source of transmission in the healthcare setting. Identifying patients who are colonized with CRE and placing these patients in isolation precautions may be an important step in preventing transmission».

Detection Methods
Alain Rambach and Patrice Nordmann have joined their efforts to develop a highly sensitive chromogenic medium, CHROMagarTM mSuperCARBATM, the new generation of chromogenic media that reaches unprecedented performances: detection of a large variety of carbapenemases KPC, NDM, VIM, IMP, OXA…with an impressive limit of detection (10 CFU/ml) even for weakly expressed carbapenemases like OXA-48, while maintaining a high level of selectivity.
