    Rise of CC398 Lineage of <em>Staphylococcus aureus</em> among Infective Endocarditis Isolates Revealed by Two Consecutive Population-Based Studies in France

    <div><p><em>Staphylococcus aureus</em> isolates from two prospective studies on infective endocarditis (IE) conducted in 1999 and 2008 and isolated from non-IE bacteremia collected in 2006 were <em>spa</em>-typed and their virulence factors were analyzed with a microarray. Both populations were genetically diverse, with no virulence factors or genotypes significantly more associated with the IE isolates compared with the non-IE isolates. The population structure of the IE isolates did not change much between 1999 and 2008, with the exception of the appearance of CC398 methicillin-susceptible <em>Staphylococcus aureus</em> (MSSA) isolates responsible for 5.6% of all cases in 2008. In 1999, this lineage was responsible for no cases. The increasing prevalence of <em>S. aureus</em> in IE is apparently not the result of a major change in staphylococcal population structure over time, with the exception of the emerging CC398 MSSA lineage.</p> </div
