Redefining a Structural Variant of Staphylococcal Cassette Chromosome mec , SCC mec Type VI

Previously we identified a SCCmec variant similar in size to type IV but with a new ccrAB allotype, allotype 4. We addressed the epidemiological relevance of this variant and found it among several strains belonging to the same clone. We propose to rename this structural variant SCCmec type VI.
