Figure. Incidence of non–multidrug-resistant methicillin-resistant Staphylococcus aureus (MRSA) strains, Geneva, Switzerland, 1993–2005. A) Number of strains collected since 1993 showing an atypical multidrug-susceptible phenotype (white bars). Also shown are the number of SCCmec IV and V (circles) isolates and number of strains containing Panton-Valentine leukocidin (PVL) (triangles). B) Evolution of the 3 most abundant clonotypes (ST80, ST88, and ST5). Despite a constant number of strains isolated since 2002, the proportion of these clones has decreased, which suggests increasing diversity of clones in our population of community acquired–MRSA.
