First identification and characterization of a plasmid co-harbouring poxtA and cfr in a clinical linezolid-resistant Staphylococcus aureus isolate
Abstract Background Linezolid remains an important treatment option for serious infections caused by Gram-positive pathogens; however, acquired oxazolidinone resistance genes carried by mobile genetic elements are an increasing clinical concern. In Staphylococcus aureus , cfr and poxtA have previously been reported together in the chromosomal mosaic transposon Tn 6349 , whereas complete plasmid-borne structures co-harbouring these genes remain poorly defined. Methods Isolate D2958 was identified by matrix-assisted …
