An ancient ecospecies of <i>Helicobacter pylori</i> found in Indigenous populations and animal adapted lineages

2023-04-28

Abstract excerpt

The colonization of our stomachs by Helicobacter pylori is believed to predate the oldest splits between extant human populations. We identify a “Hardy” ecospecies of H. pylori associated with indigenous groups, isolated from people in Siberia, Canada, USA and Chile. The ecospecies shares the ancestry of “Ubiquitous” H. pylori from the same geographical region in most of the genome but has nearly fixed SNP diff...
