RECOMBINANT STRAIN OF MYCOBACTERIUM BOVIS BACILLUS CALMETTE-GUERIN (BCG) IMMUNOGENIC COMPOSITION AND USE

摘要

The present invention relates to recombinant Mycobacterium strain that encode the mutated Escherichia coli LT heat-labile toxin or the A subunit of the mutated Escherichia coli LT heat-labile toxin. The present invention also relates to strains of Mycobacterium that encode the LT heat-labile toxin or the A subunit of the LT heat-labile toxin of Escherichia coli mutated in position 63. Specifically, the present invention relates to strains of Mycobacterium that encode the LT heat-labile toxin or the A subunit of the LT heat-labile toxin of Escherichia coli mutated in position 63 from serine to lysine. The present invention also provides immunogenic compositions that comprise the strains of the present invention. The present invention further provides for the use of said strains and immunological compositions in the production of a vaccine for preventing tuberculosis and infections caused by Mycobacterium tuberculosis. Lastly, the present invention relates to methods for preventing or treating tuberculosis in animals.
