Abstract:
The aim of this study was to compare methicillin-resistant Staphylococcus aureus strains collected in eight hospitals located in the same region of France (Brittany) over a short period (January 1999-July 2000). Ninety-two isolates of methicillin-resistant S. aureus were characterised by their pulsotype and their antibiotype. Pulsotype analysis permitted the definition of three clusters. Two of them comprised 83% of the studied isolates. Phenotypic analysis showed two major antibiotypes, widespread in Brittany but with a heterogeneous geographic distribution and one antibiotype fitting the definition of glycopeptide intermediate S. aureus. These data argue for the high epidemicity of methicillin-resistant S. aureus among the same region.
