(A) Phylogenetic relationships between Cambridgeshire CC97 isolates and most closely related isolates from a global collection10. Figure shows an unrooted maximum likelihood tree generated from core genome single nucleotide polymorphisms. (B) Phylogenetic relationships between Cambridgeshire CC130 isolates. Figure shows an unrooted maximum likelihood tree generated from core genome single nucleotide polymorphisms. The two clinical isolates are highlighted in red. The two closely related isolates from the same patient are highlighted in blue.
