Fig. 3From: Whole genome sequencing of Salmonella enterica serovars isolated from humans, animals, and the environment in Lagos, NigeriaThe minimum spanning tree (MST) of Salmonella strains (nodes) was used in this study. The node colour corresponds to the source of the strains (see legend). The allelic distances from cgMLST analysis are denoted at branches. Clusters of genetically similar strains were defined using a cut-off of 10 alleles and are visualized in greyBack to article page
