The bacterium has a very slow rate of replication, and its genetic variations account for the different strains and the growing drug resistance. <unk>  has tropism for different kinds of human cells, with preference for cells of the lung. The main natural reservoir for<unk>  are Human beings; however, the bacteria can also infect other species.
