Summary Introduction
To review:
The growth of Mycobacterium tuberculosis despite its thick envelope screening out most of thenutrients.
Introduction:
Mycobacterium tuberculosis and Mycobacterium leprae are the two species of Mycobacterium. Tuberculosis is caused by M. tuberculosis. The sequencing of the genome ofM. tuberculosisrevealed the presence of pathogenicity genes. Mycobacterium usually attacks the lungs.M. tuberculosis is an obligate aerobe, whichis non-motile. They have a slow generation time. The cell wall is made up of acidic waxes.
