Fig. 2: Global distribution of lineages, their composition by isolation source and contribution to phylogenetic lineage total number of strains.

a Bubble plot illustrating the proportion of lineages per continent. b Barplot showing the number of strains per lineage coloured by isolation source for the entire strain collection (see colour legend in c). c Barplot for the prospectively sampled representative collection of human-associated S. maltophilia complex strains per lineage coloured by human-invasive, human-non-invasive or human-respiratory. One-sided p-values for all within-lineage comparison of isolation sources can be found in Supplementary Table 3. n = 1179 S. maltophilia isolates where isolation source was known. ‘*' indicates a p-value of < 0.05 using one-sided Fisher’s exact test (for n < 5) or test of equal and given proportions corrected for multiple testing using the Benjamini–Hochberg procedure.
