title: Analysis of the Capsule of Mycobacterium tuberculosis.
abstract: Mycobacterium tuberculosis and the other pathogenic mycobacteria examined so far by electron microscopy are seen to be surrounded within host cells by an electron-transparent zone (ETZ). For Mycobacterium lepraemurium, this space between the phagosomal membrane of the infected cellthe wall of the enclosed bacteria was called a "capsular space" (1). Using light microscopic techniques (2-4), Hanks demonstrated the presence of an unstainable "halo" around some pathogenic mycobacteria and pointed out (5) that what appeared to be a capsule could be seen in several published images of pathogenic mycobacteria.
