HardyCHROM CRE Banner mockup

Hardy Diagnostics is proud to introduce HardyCHROM CRE for the screening of E. coli, K. pneumoniae,
K. aerogenes, K. oxytoca, Enterobacter cloacae complex, and Serratia marcescens.

HardyCHROM™ CRE is a selective and differential chromogenic agar medium intended for the qualitative and presumptive detection from stool specimens of Escherichia coli that are non-susceptible to carbapenems as pink colonies and KES (Klebsiella aerogenes, Klebsiella oxytoca, Klebsiella pneumoniae, Enterobacter cloacae complex, and Serratia marcescens) that are non-susceptible to carbapenems as blue colonies.

HardyCHROM™ CRE is intended as an aid in the detection, identification of colonization and control of these bacteria in a healthcare setting. HardyCHROM™ CRE is not intended to diagnose infection or guide therapy. Results can be interpreted after incubation for 18-24 hours. Subculture to non-selective medium is required for confirming identification, antimicrobial susceptibility testing and epidemiological typing.

A lack of growth or the absence of pink or blue colonies on HardyCHROM™ CRE does not preclude the presence of Escherichia coli and KES that are non-susceptible to carbapenems.

Growth Interpretation

  • Non-susceptible E. coli produces colonies that are rose to magenta in color with darker pink centers.

  • KlebsiellaEnterobacter, and Serratia spp. produce large, dark blue colonies (with or without a pink halo), are presumptive positive for carbapenem non-susceptible KES (Klebsiella aerogenesKlebsiella oxytocaKlebsiella pneumoniaeEnterobacter cloacae complex, and Serratia marcescens).

  • Colonies that are not pink to magenta, blue, or blue with pink halos are negative – No carbapenem non-susceptible Escherchia coli or KES detected.

Elevate your testing for carbapenemase producing Enterobacterales and Pseudomonas aeruginosa with NG-Test® CARBA 5

Rapid detection and differentiation of the five most common carbapenemases produced by Enterobacteriaceae and Pseudomonas aeruginosa resistance mechanisms.

NG-Test® CARBA 5 is a lateral flow assay for quick, clear detection of the “big 5” carbapenemase enzymes produced by Enterobacteriaceae and P. aeruginosa. NG-Test® CARBA 5 is the rapid test you’ve been waiting for:
  • Cost effective – Requires no special equipment. The cost per test versus PCR makes it extremely economical.
  • Easy to implementNG-Test® CARBA 5 naturally fits into your workflows and requires no specialized training, unlike molecular tests.
Patient care is the highest priority when dealing with infection control and resistant bacteria. Every minute spent searching is a minute delaying accurate treatment.
Find what you’re looking for more quickly than ever before.
With NG-Test® CARBA 5, you don’t need to guess. Simply perform the test from bacterial culture and in 15 minutes, you’ll save more than money; you’ll be saving lives.
