Characteristics of the accessory resistomes based on the ResFinder database. a Total counts of antibiotic resistance genes for individual strains of S. enterica serotypes. The different colors correspond to different antibiotics shown in the legend. b Clustering results of the accessory resistomes. The darker the color, the greater the number of related genes. c Comparison matrix of accessory ARGs within each genome. Each symbol represents the number of genes related to a specific antibiotic. The blue symbols indicate that the genomes on the x-axis and the y-axis have equal numbers of genes (nx = ny), while green for nx < ny and orange for nx > ny. If the number of the two genomes is equal, all the symbols will be arranged on the diagonal, otherwise significant shifts will deviate substantially from the diagonal
