Genomic islands in ST72 HL1 compared to USA300 and USA400.

<p>A, vSaα genomic island. B, vSaβ genomic island. C, vSaγ genomic island. Broken lines, missing ORFs; red, virulence determinants; green, type I restriction-modification system specificity subunit; yellow, lipoproteins; blue, bacteriocin-related genes; yellow, determinants; grey= ORF not identical to other strains.</p

SCC<i>mec</i> IVa of ST72 HL1.

<p>The HL1 SCC<i>mec</i> IVa element and the adjacent unique downstream region are compared to the SCC<i>mec</i> IVa elements of USA300 and USA400. SCC<i>mec</i> regions are shaded in grey boxes. Colored internal boxes in the case of HL1 show differing regions. Regions present in USA300 and USA400, but absent from HL1 are in dark grey, internal boxes. Solid grey bar, class B <i>mec</i> region; dotted grey bar, left extremity (L–C) region. Rep, replication protein; Mob, plasmid mobilization protein; Bleo-Resis, bleomycin resistance protein; Kan Nucl-T, kanamycin nucleotidyltransferase; (R), (R)-specific enoyl-CoA-hydratase; HMGCoA, hydroxymethylglutaryl CoA reductase; ACME, arginine catabolic mobile element (downstream of SCC<i>mec</i> in USA300).</p
