Core gene–based phylogenetic analysis of the 1050 Salmonella Oranienburg strains classified as clade 7 in Figure 1. Single-nucleotide polymorphisms (SNPs) were identified using the finished genome sequence of strain 0250 as a reference. Based on the 11 412 SNPs identified in 3158 core genes, a midpoint-rooted maximum-likelihood tree was constructed using IQ-TREE with a model inferred by ModelTest and 2000 bootstrap replicates. Bars represent the number of substitutions per site. The total 38 colored strains containing the 12 bacteremia-related strains, 13 strains that were clustered with the 12 bacteremia-related strains, and the 13 strains in sister branches are analyzed in Figure 3. Abbreviations: CC, continent or country; DI, detailed information of human sources; SC, sources.
