Bayesian population assignments using STRUCTURE 2.0.

(A) DISTRUCT plot of the population assignment of Cameroonian H. pylori haplotypes in a global reference dataset as determined by the “no admixture model” (K = 6) and the “linkage model” (K = 6). Each bacterial isolate is depicted by a thin vertical line, which is divided into K colored segments representing the membership coefficients in each cluster. Black lines separate isolates of different populations/subpopulations. Populations are labeled above the figure, subpopulations below the figure. Cameroonian non-Baka and Baka H. pylori haplotypes are shown on the right side of the plot. (B) DISTRUCT plots of the subpopulation assignment of H. pylori hpAfrica1 haplotypes using the “no admixture model” (K = 2, K = 3). Strains were grouped together according to their geographical source. (C) DISTRUCT plot of the population structure of H. pylori hpNEAfrica haplotypes according to the “no admixture model” (K = 2). Strains were grouped together according to their geographical source.
