[The isolation of the antigenic substances of Mycobacterium tuberculosis and the characteristics of their basic chemical components].

Different methods of isolation were used when obtaining the antigen determinants of the tuberculosis mycobacteria (tuberculins, polysaccharide, phosphatide). Main chemical components of the antigens were investigated. Most effective and economic methods of obtaining the M. tuberculosis antigens substances were chosen. The using of the obtained antigens in the test systems for diagnostics of tuberculosis discussed.
