Population structure, biogeography and transmissibility of Mycobacterium tuberculosis

Abstract

Mycobacterium tuberculosis is a clonal pathogen that has co-evolved with humans for millennia. Here, Freschi et al. reevaluate the population structure of M. tuberculosis, providing an in-depth analysis of the ancient Indo-Oceanic Lineage 1 and the modern Central Asian Lineage 3, and expanding our understanding of Lineages 2 and 4.
