  1. * Pairwise alignments were performed using the amino acid sequences of the N23 sub-domains of the FnBPA A domain. Sequences used in the alignments were from the following S. aureus strains: isotype I – 8325-4; isotype II – MRSA252; isotype III – MSSA476; isotype IV – P1; isotype V – 3110; isotype VI – 19; isotype VII – 3153.
