Low Prevalence of Cfr-Mediated Linezolid Resistance among Methicillin-Resistant Staphylococcus aureus in a Spanish Hospital: Case Report on Linezolid Resistance Acquired during Linezolid Therapy
نویسندگان
چکیده
Linezolid is an effective antimicrobial agent to treat methicillin-resistant Staphylococcus aureus (MRSA). Resistance to linezolid due to the cfr gene is described worldwide. The present study aimed to analyze the prevalence of the cfr-mediated linezolid resistance among MRSA clinical isolates in our area. A very low prevalence of cfr mediated linezolid resistance was found: only one bacteremic isolate out of 2 215 screened isolates. The only linezolid resistant isolate arose in a patient, previously colonized by MRSA, following linezolid therapy. Despite the low rate of resistance in our area, ongoing surveillance is advisable to avoid the spread of linezolid resistance.

Sir, Linezolid is a last-resort antimicrobial agent in human medicine approved for the control of serious infections caused by Grampositive pathogens. Transferable linezolid resistance is based on the multiresistance gene cfr. Although originally found in staphylococci, this gene has meanwhile been reported in various Grampositive and even Gram-negative bacteria. The emergence of the multiresis...

Linezolid, which targets the ribosome, is a new synthetic antibiotic that is used for treatment of infections caused by Gram-positive pathogens. Clinical resistance to linezolid, so far, has been developing only slowly and has involved exclusively target site mutations. We have discovered that linezolid resistance in a methicillin-resistant Staphylococcus aureus hospital strain from Colombia is...

Linezolid is often the drug of last resort for serious methicillin-resistant Staphylococcus aureus (MRSA) infections. Linezolid resistance is mediated by mutations in 23S rRNA and genes for ribosomal proteins; cfr, encoding phenicol, lincosamide, oxazolidinone, pleuromutilin, and streptogramin A (PhLOPSA) resistance; its homologue cfr(B); or optrA, conferring oxazolidinone and phenicol resistan...
