Fig. 5: Invasiveness index of ST19 and ST313 lineages.
From: Stepwise evolution of Salmonella Typhimurium ST313 causing bloodstream infection in Africa
Box plot representing the distribution of invasiveness index values for all genome sequences included in this study summarized by lineage assignment. UK-isolated ST313 refers to those described in ref. 7. Groups were compared using a two-sided Wilcoxon–Mann–Whitney test46 and the resultant P-values were all less than 0.001. Number of isolates in each group: ST19 (n = 66), ST313 L1 (n = 52), ST313 L2 (n = 550), ST313 L3 (n = 9) and UK-isolated ST313 (n = 59). In the box plot, centre lines represent median values, box limits represent upper and lower quartiles, whiskers represent 1.5× the interquartile range and individual points represent outliers. The box plot was created using R ggplot288.
