Abstract

Pulsed-field gel electrophoretic analysis of 2,144 methicillin-resistant Staphylococcus aureus (MRSA) strains isolated from patients in Spanish hospitals over a 7-year period revealed 17 predominant profiles. Typing showed the replacement of Iberian clone E1 (ST247-MRSA-I) by two prevalent clones, E7 and E8, that are closely related to each other and have the same genetic background as ST125-MRSA-IV.

PFGE patterns of representative predominant MRSA clones identified from 2,144 nosocomial MRSA strains during a 7-year period (1996 to 2002). The clones, including Iberian clone (E1) subtypes (E1a to E1d), E5 (Brazilian clone), E7 subtypes (E7a to E7c), E8 subtypes (E8a and E8 b) and λ molecular markers are shown above the lanes.
