SNP analyses based on core genome multilocus sequence typing results OXA-244-producing Escherichia coli ST38 isolates (n = 148)

Neighbour-joining tree based on the SNP analysis of 148 OXA-244-producing E. coli isolates and corresponding schematic sequence alignments. SNP analysis was conducted in Enterobase [5].

Panel A: Cluster ST38, non-cluster ST38 and non-ST38 isolates are represented by the blue, red and green bars, respectively.

Panel B: Schematic representation of sequences with the insertion highlighted in grey identified in cluster ST38 isolates shown in blue. Absence of the insertion was found in non-cluster ST38 and non-ST38 isolates shown in red and green, respectively (see text for details). Different colours represent homologous sequences.
