Novel organization of the arginine catabolic mobile element and staphylococcal cassette chromosome mec composite island and its horizontal transfer between distinct Staphylococcus aureus genotypes

Antimicrob Agents Chemother. 2013 Nov;57(11):5774-7. doi: 10.1128/AAC.01321-13. Epub 2013 Sep 3.


In this study, 425 methicillin-resistant Staphylococcus aureus (MRSA) isolates recovered in the Dutch-German Euregio were investigated for the presence of the arginine catabolic mobile element (ACME). Sequence analysis by whole-genome sequencing revealed an entirely new organization of the ACME-staphylococcal cassette chromosome mec composite island (SCCmec-CI), with truncated ACME type II located downstream of SCCmec. An identical nucleotide sequence of ACME-SCCmec-CI was found in two distinct MRSA lineages (t064-ST8 and t002-ST5), which has not been reported previously in S. aureus.
