In addition, there has been steady progress in identifying and characterizing several classes of major mycobacterial proteins; included amongst these are the secreted/export proteins of Mycobacterium tuberculosis, which several laboratories now believe may represent the key protective immunity-inducing antigens of the bacillus.</p>  a0952-7915
