Fig. 3From: The recombination dynamics of Staphylococcus aureus inferred from spA geneGraphical display of the location of polymorphic sites (SPNs and INDELs) of spA from S. aureus strains using the program HAPPLOT when aligned with S. aureus strain 18583. Polymorphic nucleotide sites based upon pairwise comparisons are represented by vertical linesBack to article page
