To download the certificate of analysis, please indicate your lot number below :


1. High Sensitive: Detection of MIC as low as 8 µg/mL.

2. Directly from specimen

3. Easy identification: Species identification by MALDI-TOF can be carried directly from a colony. 

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


Medium Description

Gain flexibility using powder rather than ready to use plates: Use the entire pack, or if there is a need for a smaller number of plates, just a portion. If kept under appropriate storage temperature, CHROMagarTM LIN-R has a more than 18 months shelf life. This flexibility is essential to avoid the waste resulting from expired-unused plates.


Focus on Linezolid-Resistant Bacteria

Gram (+) cocci pose a global threat to human health due to the emergence of resistance to antibiotics. Linezolid has a broad spectrum of activity against a variety of pathogenic Gram (+) microorganisms, 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, have been increasingly reported after approval of its clinical use. 

Although the prevalence of linezolid resistance remains low, the emergence of LIN-R strains is still a great concern. Today, linezolid sensitivity in Gram (+) clinical specimens is primarily monitored by surveillance programs in Europe and in the United States. Clinical isolates for surveillance of LIN-R strains include swabs from the nose (for screening of Staphylococcus), perianal and rectal areas (for screening of Enterococcus).
