Phylogeny of S. enterica serovar Enteritidis isolates from humans. A phylogenetic tree is generated using the maximum likelihood method with 10,077 concatenated SNPs in the core genome sequences of 197 genomes. The root is identified using S. Gallinarum 287/91 as the outgroup. Bootstrap values (> 60%) are presented on the branches. Named clades are color coded in the tree. The geographical isolation source of each isolate in the tree is indicated by colored font: Africa and South America countries, red; China, green; European countries, teal; United States, purple. The presence of replicon sequence (purple box), antimicrobial resistance genes (ARGs) and ns SNPs resulting in substitutions in the QRDR of GyrA (red box), and pseudo ARG (teal box) are indicated.
