Distance matrix of 119 strains with various topic numbers. Nine heat maps show the distance matrices when the topic number K is set to 2 (a), 3 (b), 5 (c), 10 (d), 20 (e), 30 (f), 40 (g), 60 (h), and 80 (i), respectively. The analysis was performed on the topic mixture representations of the 119 strains by the same method as shown in Fig. 4. The color histogram from blue to red indicates various degrees of similarity of topic mixtures between every pair of strains. Four groups are visualized. Group A: Typhimurium, Typhimurium var.5- and 4,[5],12:i:-; Group B: Heidelberg; Group C: Saintpaul, Paratyphi B, Schwarzengrund and Stanley; Group D: Agona
