Phylogeny of C. difficile 027/BI/NAP1 based on core genome SNPs. a, Global phylogeny (n=151 isolates). Colored nodes indicate the geographical source of the isolates. The position of the inferred root is indicated by a dashed line. b, Phylogeny of UK isolates (n=188) colored according to geographical source of isolates (gray - non-UK isolates). Dashed-line circled areas indicate the isolates with Thr82Ile substitution in gyrA associated with fluoroquinolone resistance. Black arrows show insertion of selected mobile elements.
