Colorex™ mSuperCARBA™ ™ is a selective and differential chromogenic culture medium, intended for use in the qualitative direct detection of gastrointestinal colonization with carbapenem-resistant Enterobacteria (CRE).
CPE/CPO stands for Carbapenemase Producing Enterobacteriaceae / Carbapenemase Producing Organism. This group of bacteria, e.g., E. coli, Klebsiella spp. and Enterobacter spp., are highly resistant to antibiotics (including carbapenems).
Colorex™ mSuperCARBA™ was designed to simplify the detection of CPEs, including the “Big Five” such as OXA-48 like enzymes in Enterobacterales, allowing for improved monitoring of high-risk patient groups. The distinctive colony colouration produced by different species can allow for a presumptive positive result to be assessed within 24 hours of receipt of the specimen.
Typical colour reactions are as follows:
| Organism | Expected colour |
| CPE E.coli | Dark pink to reddish |
| CPE Escherichia coli | Metallic blue |
| CPO Klebsiella pneumoniae | Translucent, +/- natural pigmentation cream to green |
| CPO Enterococcus faecalis | Cream |
| Other Gram (-) CPO | Colourless, natural pigmentation |
| Non-CPE E. coli/Coliforms | Inhibited |
| Other Gram (-) non-CPO | Inhibited |
| Gram (+) bacteria | Inhibited |
