A phylogenetic tree showing the genetic diversity of 34 equine isolates alongside reference genomes. To the right of the tree, a matrix displays the resistome and phenotype: colored dots indicate the presence of specific antibiotic resistance genes (like beta-lactams and quinolones), and a heatmap shows phenotypic resistance levels. The chart highlights that Enterobacter hormaechei strains (ST114 and ST171) carry the most acquired resistance genes compared to Huaxiibacter and Lelliottia species.
An alluvial diagram comparing two identification methods for equine bacterial strains. The left axis shows results from MALDI-TOF, and the right axis shows results from Whole Genome Sequencing (rMLST). Colored bands connecting the two sides illustrate significant discrepancies: many strains initially identified as Enterobacter spp. or "Not determined" by MALDI-TOF were reclassified as Lelliottia, Huaxiibacter, or Rahnella by genomic analysis.
