Linezolid is an important antibiotic because it has a broad spectrum of activity against a variety of pathogenic Gram (+) bacteria particularly resistant to other antibiotics, such as MRSA, VRS and VRE.

However, the emergence of strains resistant to linezolid (LIN-R) and horizontal spread of resistance linked to the cfr gene, are being increasingly reported.

Although the prevalence of linezolid resistance remains low, linezolid resistance in Gram (+) is monitored by surveillance programs in Europe and in the United States; like the LEADER initiative or the Antimicrobial Surveillance program, SENTRY.

An essential element for these surveillance programs is a tool to facilitate rapid detection of resistant isolates carriers. CHROMagar™ has therefore decided to complete its line of AMR tests to support hospital infection control teams in their fight against outbreaks.

We have developed CHROMagar™ LIN-R, the first chromogenic screening medium designed for the detection, isolation and differentiation of Staphylococci and Enterococci resistant to Linezolid.

Why choose CHROMagar™ LIN-R?

• Highly-sensitive: Detection of MIC as low as 8 μg/mL.


• Plate directly from specimen


• Easy interpretation: MALDI-TOF species identification can be carried out directly from colony


• With experience, a trained eye can differentiate between E. faecium and E. faecalis, and between S. aureus and S. epidermidis.
