1 Meticillin-resistant Staphylococcus aureus with a novel mecA homologue in human and bovine populations in the UK and Denmark: a descriptive study  Laura García-Álvarez, PhD, Matthew TG Holden, PhD, Heather Lindsay, BSc, Cerian R Webb, PhD, Derek FJ Brown, PhD, Martin D Curran, PhD, Enid Walpole, FIMLS, Karen Brooks, BSc, Derek J Pickard, PhD, Christopher Teale, MRCVS, Prof Julian Parkhill, PhD, Stephen D Bentley, PhD, Giles F Edwards, FRCPath, E Kirsty Girvan, MSc, Angela M Kearns, PhD, Bruno Pichon, PhD, Robert LR Hill, PhD, Anders Rhod Larsen, PhD, Robert L Skov, MD, Prof Sharon J Peacock, PhD, Prof Duncan J Maskell, PhD, Dr Mark A Holmes, VetMB  The Lancet Infectious Diseases  Volume 11, Issue 8, Pages (August 2011) DOI: /S (11) Copyright © 2011 Elsevier Ltd Terms and Conditions

2 Figure 1 Comparison of the type XI SCCmec of LGA251 with other SCC elements Schematic diagram of type II SCCmec of meticillin-resistant Staphylococcus aureus MRSA252 (top), type IV SCCmec of MW2 (upper middle), type XI SCCmec of LGA251 (lower middle), and the SCCmec-like element of Macrococcus caseolyticus JCSC7096 (bottom). The names of the coding sequences associated with drug and metal resistance are provided. Coding sequences are marked in the direction of transcription as arrows. Coding sequences belonging to the mec and ccr complexes, and IS431 are coloured, with homologues given the same colour; the individual genes belonging to these groups are named. Light pink shading joins regions that are conserved between elements. The coloured boxes at the end of the SCC elements mark the integration site sequence (blue, attL; green attR).

3 Figure 2 Geographical distribution of the bovine and human meticillin-resistant Staphylococcus aureus strains carrying the mecALGA251 gene in England The colouring of the symbols and labels indicates common lineage, defined on the basis of spa typing, multilocus sequence typing, or both. spa types and multilocus sequence types are indicated in the labels.
