Journal ArticleDOI

A new evolutionary scenario for the Mycobacterium tuberculosis complex

TL;DR: The distribution of 20 variable regions resulting from insertion-deletion events in the genomes of the tubercle bacilli has been evaluated and contradict the often-presented hypothesis that M. tuberculosis, the etiological agent of human tuberculosis evolved from M. bovis, the agent of bovine disease.
Journal ArticleDOI

Identification of variable regions in the genomes of tubercle bacilli using bacterial artificial chromosome arrays.

TL;DR: Comparisons of the BAC libraries of Mycobacterium tuberculosis and the vaccine strain and the complete genome sequence of M. bovis BCG uncovered a third class of deletions consisting of two M. tuberculosis H37Rv loci, RvD1 and RVD2, deleted from the genome relative to M.bovis.
Journal ArticleDOI

Genome plasticity of BCG and impact on vaccine efficacy.

TL;DR: The combined findings suggest that early BCG vaccines may even be superior to the later ones that are more widely used, and that further amplification of the DU2 region is ongoing, even within vaccine preparations used to immunize humans.
