  1. aEmboldened and italicised nucleotides are specific to sub-clade C2 EC958 and isolates within the North Wales sub-cluster, respectively
  2. bConsequence of SNP relative to EC958 (C2).
  3. bSynonymous change (Syn); non-synonymous changes to protein-coding genes are shown by single letter amino acid abbreviation (EC958 sequence on the left, SNP impact on right); blank lines indicate variant in intergenic region
