Repeated out-of-Africa expansions of <i>Helicobacter pylori</i> driven by replacement of deleterious mutations

2021-06-06

Abstract excerpt

Helicobacter pylori lives in the human stomach and has a population structure which resembles that of its host. However, H. pylori from Europe and the Middle East trace a substantially higher fraction of ancestry from modern African populations than the humans that carry them. Here, we used a collection of Afro-Eurasian H. pylori genomes to show that this African ancestry is due to at least three distinct admixt...
