Local Adaption of Tuberculosis, Not Human Migration, Spread TB Resistance Mutations (2 of 3)

Caption

Within-country diversity as assessed by mean pairwise SNP distances (only including well-sampled countries). Vertical dashed lines indicate median values. Embedded pie charts summarize sublineage distribution within each country. The Simpsons diversity index (1-D) was calculated at the level of subspecies and the estimate indicated in the top of each county panel (where higher values correspond to increased diversity). This material relates to a paper that appeared in the Oct. 17th, 2018, issue of Science Advances, published by AAAS. The paper, by O.B. Brynildsrud at Norwegian Institute of Public Health in Oslo, Norway, and colleagues was titled, "Global expansion of Mycobacterium tuberculosis lineage 4 shaped by colonial migration and local adaptation."
