Comparative genomics of metabolic pathways in Mycobacterium species: gene duplication, gene decay and lateral gene transfer

The genus Mycobacterium comprises significant pathogenic species that infect both humans and animals. One species within this genus, Mycobacterium tuberculosis, is the primary killer of humans resulting from bacterial infections. Five mycobacterial genomes belonging to four different species (M. tuberculosis, Mycobacterium bovis, Mycobacterium leprae and Mycobacterium avium ssp. paratuberculosis) have been sequenced to date and another 14 …
