Chromogenic media for ESBL screening
Help promote effective infection control through reliable screening* of extended-spectrum beta lactamase-producing enterobacteriaceae (ESBL) with CHROMID® ESBL selective chromogenic media.
- ESBL screening in 18-24 hours
- Validated on variety of specimens: rectal swabs, urine, respiratory secretions and others
- Patented substrate and antibiotic mix enables direct identification
*ESBL production must be confirmed
Do you need more information
Today’s healthcare environment is more complex and challenging than ever before, with multi-drug resistant organisms (MDRO) and related risk of healthcare associated infection (HAI) outbreaks among the most critical concerns. Many healthcare associated infections are caused by enterobacteriaceae. When these bacteria produce extended-spectrum β-lactamase (ESBL) enzymes, they become resistant to our most common antibiotics, and are particularly likely to lead to morbidity and mortality from bloodstream infections. ESBL-producing enterobacteriaceae are recognized worldwide as nosocomial pathogens of major importance, listed as a “serious threat” by the Centers for Disease Control1. Rapid, reliable screening of ESBL is essential to improved patient care, infection control and outbreak management.

Support effective infection control
CHROMID® ESBL is part of the bioMérieux SMART range of media, developed specifically to address the challenges of MDRO and HAI. CHROMID® ESBL is based on an agar with a patented mixture of antibiotics designed specifically to enable the selective growth of ESBL-producing enterobacteriaceae* and chromogenic substrates for the direct identification of the most frequently encountered ESBL-producing enterobacteriaceae. CHROMID® ESBL provides results in 18-24 hours, enabling timely delivery of results to support effective infection control measures for better patient outcomes and cost-containment thanks to faster responses.
CHROMID® ESBL provides rapid, easy-to-read results
* ESBL production must be confirmed by additional tests
Rapid, sensitive and specific
CHROMID® ESBL provides high sensitivity thanks to the inclusion of the antibiotic Cefpodoxime, the marker of choice for this resistance mechanism. Time-to-results is also shortened by a high level of specificity and the reduced number of confirmation tests needed. After optimal incubation of 18 hours, you’ll be confident in the reliability of easy-to-read results with the specific coloration enhanced by chromogenic media:
- Escherichia coli: pink to burgundy colouration of ß-glucuronidase-producing colonies
- KESC (Klebsiella, Enterobacter, Serratia, Citrobacter): green/blue to browny-green colouration of ß-glucosidase-producing colonies
- Proteeae (Proteus, Providencia, Moraganella): dark to light brown colouration of deaminase-expressing strains.
