Phylogenetic analysis of distinct Salmonella enterica serovar Enteritidis lineage since 2020, South Korea. Maximum-likelihood phylogenetic tree was constructed for whole-genome single-nucleotide polymorphisms of Salmonella Enteritidis from South Korea (n = 223) and isolates sequenced in this study (n = 38). Red text indicates isolates from this study. Innermost ring indicates clades separated by using FastBAPS (20), followed by sources of isolates. Five outer rings indicate the presence of different prophages; red boxes indicate the presence of prophages with a total count of >30. Isolation year is indicated at the end of each isolate number. Scale bar indicates number of single-nucleotide polymorphisms per site.
