Structures of SCCs and SCCmecs carried by BD GeneOhm MRSA assay-negative strains. Structures of elements are illustrated based on the nucleotide sequences deposited in the DDBJ/EMBL/GenBank databases as follows: panel A (JCSC6838), AB774373; panel B (J266), AB774374; panel C (JCSC4610), AB773816; panel D (JCSC7481), AB774378. Red arrowheads indicate the location of integration site sequences of SCC that comprise sequences of direct repeats (DRs). Open reading frames (ORFs) are colored as follows: yellow, transposase insertion sequences; red, resistance genes; green, ORFs related to sorbitol utilization; pink, ORFs in ccr gene complexes carrying ccrA and ccrB genes; blue, ORFs in ccr gene complexes carrying ccrC.
