Characterization of a novel cfr/fexA-carrying SCCmec variant from a Mammaliicoccus sciuri isolated from henhouses.

The article discusses the characterization of a novel composite SCCmec ⅢA variant from a multi-resistant M. sciuri strain isolated from a henhouse in China. The strain, WHA07, exhibited resistance to oxacillin, linezolid, and florfenicol, and contained resistance genes such as cfr, fexA, tet(M), and qacG. The study provides evidence of the integrative recombination of cfr and fexA from plasmid to mobile SCCmec element in the chromosome, suggesting potential transfer of these resistance genes among staphylococci.
