Description:
Two prehistoric migrations peopled the Pacific. One reached New Guinea and Australia, and a second, more recent, migration extended through Melanesia and from there to the Polynesian islands. These migrations were accompanied by two distinct populations of the specific human pathogen Helicobacter pylori, called hpSahul and hspMaori, respectively. hpSahul split from Asian populations of H. pylori 31,000 to 37,000 years ago, in concordance with archaeological history. The hpSahul populations in New Guinea and Australia have diverged sufficiently to indicate that they have remained isolated for the past 23,000 to 32,000 years. The second human expansion from Taiwan 5000 years ago dispersed one of several subgroups of the Austronesian language family along with one of several hspMaori clades into Melanesia and Polynesia, where both language and parasite have continued to diverge.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2827536/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2827536/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moodley, Yoshan -- Linz, Bodo -- Yamaoka, Yoshio -- Windsor, Helen M -- Breurec, Sebastien -- Wu, Jeng-Yih -- Maady, Ayas -- Bernhoft, Steffie -- Thiberge, Jean-Michel -- Phuanukoonnon, Suparat -- Jobb, Gangolf -- Siba, Peter -- Graham, David Y -- Marshall, Barry J -- Achtman, Mark -- R01 DK062813/DK/NIDDK NIH HHS/ -- R01 DK062813-05/DK/NIDDK NIH HHS/ -- R01 DK62813/DK/NIDDK NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2009 Jan 23;323(5913):527-30. doi: 10.1126/science.1166083.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur Infektionsbiologie, Department of Molecular Biology, Chariteplatz 1, 10117 Berlin, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19164753" target="_blank"〉PubMed〈/a〉
