Abstract
Author Summary Genetic analyses of Helicobacter pylori have illuminated human migrations and the history of human infection by these bacteria. Both humans and H. pylori originated in Africa, and have been intimately associated for at least 100,000 years. We hypothesized that communities who still live in relative isolation might provide further details about the evolutionary history of H. pylori in Africa. We therefore investigated H. pylori within Baka Pygmies of southeast Cameroon, who live as hunter-gatherers in the tropical rainforest, and compared those bacteria to H. pylori from neighboring farming populations of non-Baka ethnicities. Unexpectedly, Baka Py...
