Figure 3. Temporal stability of accessory gene pool.

Figure 3

Odds ratios for prevalence of individual OGs in the accessory genome whose frequency significantly altered at bottleneck shortly post PCV7 (2007) or during re-expansion (2008–2011), compared to pre PCV7 (2001–2006) The X-axis indicates the proportion of isolates carrying each OG in 2001 while the Y-axis indicates the log transformed odds ratio of strains carrying each OG in 2007 (green dots), and post PCV7 (blue dots), relative to pre PCV7.
