MOESM4 of Helicobacter pylori virulence genes of minor ethnic groups in North Thailand

Additional file 4. Population of H. pylori Maesot strains by STRUCTURE. The H. pylori strains from 24 Thai, 20 Hmong, 15 Karen and 7 Thai-Chinese were analyzed by STRUCTURE with K from 8–15. Each horizontal bar represent one strain, and the color in a line are proportional to the probabilities that the strain belong to each population. Each color square represented the strain from Thai, Hmong, Karen and Thai-Chinese. The H. pylori Maesot strains were hspEAsia, hpAsia2 and hpEurope. Interestingly, H. pylori Hmong and Thai-Chinese strains were located in hspEAsia while H. pylori Karen strains were belonged to hpAsia2. Thai H. pylori strains were located in three populations
