The Staphylococcus aureus lineage-specific markers collagen adhesin and toxic shock syndrome toxin 1 distinguish multilocus sequence typing clonal complexes within spa clonal complexes.
Spa typing/based upon repeat pattern (BURP) sometimes cannot differentiate multilocus sequence typing (MLST) clonal complexes (CCs) within spa-CCs. It has been observed previously that virulence factors, such as collagen adhesin (CNA) and toxic shock syndrome toxin 1 (TSST-1), are associated with certain Staphylococcus aureus lineages. Analysis of methicillin-sensitive and methicillin-resistant S. aureus by spa typing/BURP and detection of CNA and TSST-1 observed an association between CNA and MLST CC1, 12, 22, 30, 45, 51, and 239 and between TSST-1 and MLST CC30. In spa-CC 012, associated with MLST CC7, CC15, and CC30, MLST CC30 could be distinguished from MLST CC7 and CC15 with CNA and TSST-1 as lineage-specific markers. Lineage-specific markers can overcome clustering of nonrelated MLST CCs into 1 spa-CC.
