Colorex™ mSuperCARBA™ is a selective chromogenic medium that has been developed for the detection and isolation of carbapenemase producing Enterobacteriaceae (CPE). Nosocomial infections due to CPE are particularly difficult due to the limited treatment options. Therefore, this medium is designed to simplify the detection of CPE carriers and to allow for improved monitoring of high risk patient groups. The distinctive colonial colouration of the various species can reduce the need for additional follow up testing allowing many positive results to be issued within 24 hours of receipt of the sample. All presumptive positive colonies should be confirmed for carbapenemase production.
Typical colour reactions are as follows:
Escherichia coli – Red/Pink colonies;
Klebsiella spp., Enterobacter spp., & Citrobacter spp. – Metallic blue colonies;
Other Gram –ve CPE – Colourless colonies;
Carbapenem sensitive bacterial species, Gram +ve bacterial species & yeasts – Inhibited.
