Chromatic CRE

Chromatic CRE contains a mixture of carbapenems for screening a wide variety of carbapenem-resistance mechanisms and provides presumptive identification of E. coli and the Klebsiella, Enterobacter, Serratia and Citrobacter (KESC) group directly from clinical specimens.

Carbapenems, successfully used to treat multi-resistant Gram-negative bacterial infections, including ESBL positive strains, are not efficacious against the Enterobacteriaceae resistant to carbapenems, thus generating a significant risk of hospital-acquired infections.
