The overlap of preterm infant AMR contigs across four ST131 subclade C2 assemblies (8289_1#3, 8289_1#24, 8289_1#27, 8289_1#34), two ST131 reference genomes (EC958 and SE15) and two HMP assemblies (83 972 and 3_2_53FAA). Top: The intersection sizes (y-axis) and the numbers of AMR contigs per set showed that most (210) AMR contigs were shared across all isolates. The non-unique AMR contigs indicated smaller numbers of unique AMR genes, so EC958’s 17 AMR contigs (red) corresponded to nine unique bla
CMY genes (Table S2); and 8289_1#24’s nine contigs (green) represented four aminoglycoside and tetracycline resistance genes (Table S3). All Clade C bar 8289_1#27 had 12 contigs (blue) denoting to five bla
TEM genes (Table S4). Bottom: The numbers of AMR contigs per sample with the corresponding sets (coloured circles).
