Principal component analysis plot comparing accessory (noncore) genome of chromosome contigs of strains of Salmonella enterica serovar Paratyphi B variant Java sequence type 28. Oval rings indicate clusters I and II. Cluster I grouped together historical strain IP_6155/87 with all strains from Europe and some from Latin American. Cluster II grouped Latin America strains only. Cluster II was associated with a prophage sequence highly similar to the Salmonella phage SEN34 (National Center for Biot

Figure 3. Principal component analysis plot comparing accessory (noncore) genome of chromosome contigs of strains of Salmonella enterica serovar Paratyphi B variant Java sequence type 28. Oval rings indicate clusters I and II. Cluster I grouped together historical strain IP_6155/87 with all strains from Europe and some from Latin American. Cluster II grouped Latin America strains only. Cluster II was associated with a prophage sequence highly similar to the Salmonella phage SEN34 (National Center for Biotechnology Information reference sequence no. NC_028699.1). The prophage sequence was absent in strains from cluster I.
