Maximum likelihood phylogenetic trees of alpB and hofC genes.

<p>Leaves are shaded according to geographical origin and the <i>H</i>. <i>pylori</i> population assignment according to the FineSTRUCTURE analysis is marked at the base of each leaf. A) AlpB. A black dot with an asterisk marks the branch for which the joint Latin American and Asian clade segregate from the others. B) HofC. The black dot with an asterisk marks the branch at which the South American clade segregates from the others.
