Figure 4

Maximum-likelihood SNP-based phylogeny of APEC whole-genome sequences. Nodes' shape and color indicate the broiler production stage and production chain, respectively. The left, colored ribbon specifies the hierBAPS clusters. The right ribbon with alternating dark and light gray segments, marks different STs. Isolates belonging to the same ST and indicated with the same number of asterisks (*) differed by <50 SNPs. Scale bar refers to the branch lengths, which are measured in the number of substitutions per site.
