Figure 2

Global phylogenetic placement of isolates from study of multiple introductions and cross-sector transmission of Salmonella enterica serovar Infantis carrying blaCTX-M-65 gene, South Korea, 2022–2024. The cladogram was inferred from the global whole-genome single-nucleotide polymorphism dataset, and branches without South Korea isolates were collapsed for clarity. The inner ring denotes country of origin, and the outer ring denotes isolates sequenced in this study. Numbers at nodes indicate FastTree (23) support values >0.9.
