Comparison of the genomes of 3480, 36950, HN06, Pm70, M1404, BUKK, TX1, THA, THD, THF, ATTK, Faisal, Islm, Pesh, PVAcc, V1 and Karachi with the genome of the PVAcc strain.

<p>The three inner rings show the DNA size, GC content and GC skew of the reference genome (PVAcc strain). The 17 outer rings show regions of the comparison genomes that match the reference genome PVAcc and in the order (inside to outside) 3480, 36950, HN06, Pm70, M1404, BUKK, Tx1, THA, THD, THF, ATTK, Faisal, Islm, Pesh, PVAcc, V1 and Karachi. Regions 1–4 on the outside identify particular regions of difference between the strains that are potential prophage elements. The position of the type B capsule locus is also noted between regions 2 and 3. This figure was drawn using BLAST ring image generator (BRIG) [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0130296#pone.0130296.ref039" target="_blank">39</a>].
