Genomics and the evolution, pathogenesis, and diagnosis of tuberculosis

Abstract

Tuberculosis kills nearly 2 million people annually, and current approaches to tuberculosis control are expensive, have limited efficacy, and are vulnerable to being overcome by extensively drug-resistant strains of Mycobacterium tuberculosis. Determination of the genome sequence of M. tuberculosis has revolutionized tuberculosis research, contributed to major advances in the understanding of the evolution and pathogenesis of M. tuberculosis, and facilitated development of new diagnostic tests with increased specificity for tuberculosis. In this review, we describe some of the major progress in tuberculosis research that has resulted from knowledge of the genome sequence and note some of the problems that remain unsolved.

The phylogenetic scheme is based on informative markers present or absent in the progeny of each lineage. Markers in boxes include lost RD regions, SNPs, lost spoligotype spacers, and deletions in the pks15/1 and TbD1 loci. The seven species of the M. tuberculosis complex and their respective natural hosts are shown, as well as the three principal genetic groups of M. tuberculosis and their representative strains.
