Pathogenicity islands occurrence in epidemic MRSA strains from Russia and Kazakhstan

摘要

Background: MLST analysis of MRSA isolates from Southern Europe, the United States, and South America showed that nearly 70% of them belong to five major pandemic clones, namely the Iberian (MLST sequence type [ST] 247; SCCmec IA), Brazilian (ST 239; SCCmec IIIA), Hungarian (ST 239; SCCmec III), New York/Japan (ST 5; SCCmec II), and Pediatric (ST 5; SCCmec IV) clones [Aires de Sousa, M., de Lencastre H., 2004]. It is hypothesized that these clones are particularly transmissible and/or well adapted to the hospital environment [Blanc, D.
