Phylogenetic analysis of OXA-244-producing Escherichia coli ST131, Italy, December 2022–July 2023 (n = 4)
NA: not available.
Maximum-likelihood phylogeny of 52 E. coli ST131 strains inferred on coreSNPs visualised using iTOL v6, including the four Italian OXA-244-producing E. coli ST131 (red labels) and 48 from the BV-BRC database (grey labels). Labelled in orange are the two Italian OXA-244-producing E. coli ST131 collected from water. The presence/absence matrix shows the pattern of resistance determinants (blue and red dots), toxin determinants (red square) and resistance determinants (red).
