Abstract:
The subject of the present invention is the identification of nucleotide and peptide sequences which make it possible in particular to distinguish, in diagnostic terms, an immunization resulting from a BCG vaccination from an M. tuberculosis infection. The sequences in question are specific either to M. bovis BCG/M. bovis, or to M. tuberculosis. The subject of the present invention is also a method for detecting the sequences in question, a method for detecting antibodies generated by the products of expression of these sequences and the kits for carrying out these methods. Finally, the subject of the present invention is novel vaccines.
