Reveal pathogens! bioMérieux CHROMID   range puts it in living color

Multi-drug resistant organisms (MDRO) and healthcare-associated infections are major patient-care and economic challenges for healthcare systems. CHROMID chromogenic media for simultaneous culture and identification offers easy-to-read results with color intensity and specificity. 






Detect resistant organisms

Urinary tract infections


CHROMID CARBA SMART and the new CHROMID Colistin R (COLR) are part of bioMérieux’s CHROMID MDRO range for the screening of multi-drug resistant organisms.

  • Help ensure patients get the right treatment at the right time.
  • Help fight antimicrobial resistance and sustain antibiotic efficacy for the future.

CHROMID Colistin R: What do the experts say?

“CHROMID Colistin R agar represents a selective and specific method to perform surveillance studies to detect colistin-resistant Enterobacteriaceae using both stool and swabs samples.”
– Garcia-Fernandez, et. al., 2018 (see ref. below)

CHROMID   Colistin R (COLR)

Multidrug-resistant Gram-negative bacteria infections are serious and hard to treat. A last-line antibiotic, Colistin might offer a solution… but what about colistin resistance? The new CHROMID Colistin R agar (COLR) can be used for screening colistin-resistant Gram-negative bacteria and for qualitative resistance detection to colistin from isolated colonies.

  • Screening of Enterobacteriaceae colistin-resistant micro-organisms in clinical and veterinary samples: E.coli, K.pneumoniae, Enterobacter spp and Salmonella spp
  • Results in 18-24 hours after 4-5 hour enrichment* 
  • Facilitates identification of colistin-resistance carriers

Carbapenemase-producing Enterobacteriacae (CPE) are multidrug-resistant bacteria sometimes implicated in healthcare-associated infections (HAI) and even epidemics. Rapid detection of CPE contributes to better infection prevention and control, patient care and epidemiological monitoring. Screen for all CPE in just one step with CHROMID CARBA SMART selective chromogenic media bi-plate.

  • Bi-plate for complete screening:
       - OXA-48 on one side
       - Other CPE, notably KPC and NDM-1, on the other
  • Easy-to-use, single-step process
  • Validated for both rectal swabs and stool specimens*
  • Incubation in 18/24 hours


CHROMID CARBA SMART: What do the experts say?

“When [CHROMID OXA-48 is] used with CHROMID CARBA, this combination of media potentially offers a highly effective solution for detection of Enterobacteriaceae with any commonly encountered carbapenemase.”
– Zarakolu P., et al., 2015 (see ref. below)


Urinary tract infections (UTIs) are among the most commonly seen infections in the clinical environment. UTIs are involved in up to 40% of healthcare-associated infections (HAI) and are increasingly caused by multidrug-resistant organisms.

CHROMID   CPS   Elite for urinary tract infections

CHROMID CPS Elite enables the isolation, enumeration and direct or presumptive identification of organism involved in urinary tract infections.

  • Sensitivity of detection and specificity of coloration: Easy reading – even with mixed cultures*
  • Transparent or opaque versions available
  • Incubation: 16/18 hours for E. Coli



CHROMID CPS Elite: What do the experts say?

“CHROMID CPS Elite is accurate for uropathogen identification, reduces consumable usage, and may expedite the identification of E. coli in clinical specimens.”
– Yarbrough, et. al., 2016 (see ref. below)
