摘要:
Shuttle vectors for the introduction of DNA into mycobacteria comprising at least one functional replication origin in said mycobacteria, another functional replication origin in other bacteria, an enzymatic cleavage site providing for the insertion of DNA coding for a protein susceptible of being expressed in the mycobacteria, characterized in that the vectors also carry a gene which makes the mycobacteria resistant to a compound containing a heavy metal.

摘要:
The present invention relates to a life attenuated Bordetella pertussis vaccine which is deficient for tracheal cytotoxin (TCT), pertussis toxin (PTX), and dermonecrotic toxin (DNT) for prophylaxis or treatment of an allergen-driven airway pathology.
摘要:
The invention concerns a M. tuberculosis complex mycobacteria specific fragment of nucleic acids, comprising a nucleotide chain selected among the SEQ ID NO. 1 sequence, the SEQ ID No 2 sequence, their complementary sequences or the nucleic acid sequences capable of being hybridised with one of the preceding sequences in conditions of high stringency. The invention also concerns uses of said sequences for the detection and differential diagnosis of mycobacteria members of the M. tuberculosis complex, in particular the BCG differential diagnosis of other members of the complex.
摘要:
The invention features peptide sequences enabling mycobacteria adhesion to host cells, in particular to epithelial cells. More particularly, the invention features a mycobacterial antigen of the heparin-binding haemagglutinin type (HBHA) obtained from Mycobacterium bovis BCG or Mycobacterium tuberculosis. The invention also features a recombinant peptide sequence enabling mycobacteria adhesion to host cells. The invention particularly features the expression product of an Escherichia coli strain transformed with a nucleotide sequence coding for a protein enabling mycobacteria adhesion to host cells. These peptide sequences can be used in immunogenic compositions, for preparing vaccines against mycobacterial infections, and for mycobacterial infection serological diagnosis.
摘要:
The invention relates to compositions and vaccines that include a mutated Bordetella strain for treating or preventing an influenza infection in a mammal. In addition, the invention further provides methods for protecting a mammal against infection by influenza and/or eliciting an immune response against an influenza virus in a mammal using the composition or vaccine.
