Niche-associated genetic features identified through genome-wide association studies (GWAS). A A heatmap showing the presence of significantly associated genetic features (rows), among the 2456 Klebsiella pneumoniae genomes from humans and animals (columns), coloured by niche (inset legend). All features were positively associated with the animal niche. B Proportions of genomes with genetic features by niche and C source. The total number of K. pneumoniae genomes per niche and source are indicated on top of the columns. D Annotation of genetic features. See Additional file 2: Table S6 and Additional file 3: Fig. S11 for more detail. Genes annotated with more than one name are separated by a semicolon, unitigs found in multiple genes are separated by a slash
