Figure 2. Distribution of SNPs in the S. aureus 8325 and 8325-4 strain lineages.

Figure 2

Thirteen of the SNPs including the 63 bp deletion detected in 8325-4seq and described in Table 2 were analyzed by PCR from gDNA and direct sequencing for their distribution using strains collected from various laboratories worldwide. Shown in the matrix are 6 strains of 8325 pedigree group prior to prophage removal (white box), 10 strains from the 8325-4 pedigree after prophage Φ11, 12, and 13 removal (dark gray box), and one intermediate strain, RN25/NRS133, which retains prophage Φ13 (light gray box). Each SNP is indicated (top) together with coordinates from the 8325 reference genome (bottom) deposited as Genbank NC_007795.1. Strain abbreviations used are as described in Table 3. WT: wild type, +T: insertion of T, ‘ -‘ denotes SNP not tested.
