The implementation of the new clustering algorithm Based Upon Repeat Pattern (BURP) into the Ridom StaphType software too[ enables clustering based on spa typing data for Staphylococcus aureus. We compared clustering results obtained by spa typing/BURP to those obtained by currently well-established methods, i.e.. Smal macrorestriction analysis and multilocus sequence typing/eBURST. A total or 99 clinical S. aureus strains, including MRSA and representing major clonal lineages associated with important kinds of infections which have been prevalent in Germany and Central Europe during the last 10 years. were used for comparison. Smal macrorestriction analysis revealed the highest discriminatory. power. and clustering results for all three methods resulted in concordance values ranging from 96.8% between the two sequence-based methods to 93.4% between spa typing/BURP and Small macrorestriction/cluster analysis. The results of this study indicate that spa typing, together with BURP clustering, is a useful tool in S. aureus epidemiology, especially because of ease of use and the advantages of unambiguous sequence analysis as well as reproducibility and exchange of typing data.
