Bacillus Calmette–Guérin (historically Vaccin Bilié de Calmette et Guérin commonly referred to as Bacille de Calmette et Guérin or BCG) is a vaccine against tuberculosis that is prepared from a strain of the attenuated (virulence-reduced) live bovine tuberculosis bacillus Mycobacterium bovis that has lost its virulence in humans by being specially subcultured in a culture medium usually Middlebrook 7H9.
