Figure 4 Helicobacter pylori core genome tree based on 1121 core genes with 375 publicly available Helicobacter pylori genomes from Europe, Asia and Africa including the Iceman (in bold). The core genome analysis was performed using the Roary pan-genome analysis tool[44] followed by phylogenomic analysis using the PhyML tool v 3.1[45].
