Resistant Drug	Cefoxitin		Drug Info
Molecule Alteration	Expression	Up-regulation
Experimental Note	Identified from the Human Clinical Data
In Vitro Model	Staphylococcus aureus RN4220		1280
	Staphylococcus aureus M10/0061		1280
	Staphylococcus aureus M10/0148		1280
	Staphylococcus aureus WGB8404		1280
Experiment for Molecule Alteration	Whole genome sequence assay; Allelic frequency measurement assay
Experiment for Drug Resistance	Disk diffusion test assay; Etest assay
Mechanism Description	Methicillin resistance in staphylococci is mediated by penicillin binding protein 2a (PBP 2a), encoded by mecA on mobile staphylococcal cassette chromosome mec (SCCmec) elements.Whole-genome sequencing of one isolate (M10/0061) revealed a 30-kb SCCmec element encoding a class E mec complex with highly divergent blaZ-mecA-mecR1-mecI, a type 8 cassette chromosome recombinase (ccr) complex consisting of ccrA1-ccrB3, an arsenic resistance operon, and flanking direct repeats (DRs).
