Fig. 7. Small plasmids are enriched in SaPI-containing genomes.

a Venn diagram indicating S. aureus genomes carrying different MGE (n = 295 genomes). The frequency of genomes carrying each particular MGE type is denoted by (%), while the numbers indicate the absolute number of genomes that fall into each category. See also Supplementary Data 2. b Distribution of sizes of the plasmids present in the S. aureus genomes analysed in this study. The colour code indicates whether the plasmids were present in genomes which also contained SaPIs (red) or not (grey). The vertical dashed line indicates the size limit between “small” and “large” plasmids.
