Fig. 1: Phylogenetic context of elephant VF20/112 isolates.
From: Genomic insights into the 2020 mass die-off event among African elephants
The three elephant VF20/112 isolates, the lion isolate, the calf isolate, and the six Bisgaard taxon 45 isolates clustered together, whereas the two cheetah isolates formed a separate cluster within the P. multocida subsp. multocida/gallicida clade. The three elephant VF20/112 isolates formed a late-branching subcluster within Bisgaard taxon 45. The maximum-likelihood phylogeny was built from a core-genome single-nucleotide polymorphism (SNP) alignment (150,135 SNPs) after putative recombination sites were removed. The length of the broken branches was reduced by fivefold. Branch support values above 90% are indicated by filled circles at the nodes. The scale bar denotes substitutions per variable site.
