Courtesy of Roland BroschThe regions absent from the attenuated vaccine strain Mycobacterium bovis BCG Pasteur relative to the M. tuberculosis H37Rv genome are shown as gray boxes. Open reading frames (ORFs) are represented as pointed boxes showing the direction of transcription, with colors reflecting the functional classification of the ORFs similar to the ones on the TubercuList server http://genolist.pasteur.fr/TubercuList/.Not long after the genome sequence of Mycobacterium tuberculosis was
