Abstract excerpt
Among the genotypes that prevail in the modern spectrum of Mycobacterium tuberculosis strains, the Beijing genotype is the one that causes major concern, as it is geographically widespread and it is considered hypervirulent. Comparative genomic studies have shown that Beijing strains have principally evolved through mechanisms of deletion of chromosomal regions, designated regions of difference (RD), and...
