Abstract

Attenuated strains of Mycobacterium, particularly species of the tuberculosis complex, have the mycobacterial cell entry (mce) gene functionally disabled. The gene may be disabled by an insertion into the gene which disrupts the mycobacterial cell entry function thereof of a selectable marker which is used for screen for homologous recombinants in which a double cross-over event has been effected. The attenuated strains may be used in the immunization of hosts against Mycobacterium disease.
