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。强制强制强制执行（LIN-R）和强制执行（resistance）linked to the horizontal spread of resistance linked to thecfrgene，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 of 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 ofStaphylococcus），perianal and rectal areas（for screening ofEnterococcus）。
CHROMagar™，™LIN-R is a chromogenic screening medium for the detection，isolation and differentation of strains ofStaphylococcusand，andEnterococcusresistant to linezolid。
