Local adaptation in populations ofMycobacterium tuberculosisendemic to the Indian Ocean Rim

2020

AbstractLineage 1 (L1) and 3 (L3) are two lineages of theMycobacterium tuberculosiscomplex (MTBC), causing tuberculosis (TB) in humans. L1 and L3 are endemic to the Rim of the Indian Ocean, the region that accounts for most of the world’s new TB cases. Despite their relevance for this region, L1 and L3 remain understudied. Here we analyzed 2,938 L1 and 2,030 L3 whole genome sequences originating from 69 countries. We show that South Asia played a central role in the dispersion of these two lineages to neighboring regions. Moreover, we found that L1 exhibits signatures of local adaptation at theesxHlocus, a gene coding for a secreted effector that targets the human endosomal sorting complex,…
