摘要:
Compounds and methods for inducing protective immunity against tuberculosis are disclosed. The compounds provided include polypeptides that contain at least one immunogenic portion of one or more M. tuberculosis proteins and DNA molecules encoding such polypeptides. Such compounds may be formulated into vaccines and/or pharmaceutical compositions for immunization against M. tuberculosis infection, or may be used for the diagnosis of tuberculosis.
摘要:
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.
摘要:
Compounds and methods for diagnosing tuberculosis are disclosed. The compounds provided include polypeptides that contain at least one antigenic portion of one or more M. tuberculosis proteins, and DNA sequences encoding such polypeptides. Diagnostic kits containing such polypeptides or DNA sequences and a suitable detection reagent may be used for the detection of M. tuberculosis infection in patients and biological samples. Antibodies directed against such polypeptides are also provided.
摘要:
The present invention provides polypeptides comprising an immunogenic portion of a M. vaccae protein and DNA molecules encoding such polypeptides, together with methods for their use in the diagnosis and treatment of mycobacterial infection. Methods for enhancing the immune response to an antigen including administration of M. vaccae culture filtrate, delipidated M. vaccae cells or delipidated and deglycolipidated M. vaccae cells are also provided.
摘要:
Antigenic and/or immunoregulatory material derived from Mycobacterium vaccae is useful for delaying the onset of AIDS with or without associated tuberculosis.
摘要:
Vaccines based on one or more combinations of majorly abundant extracellular products of pathogens and methods for their use and production are presented. The most prevalent or majorly abundant extracellular products of a target pathogen are selected irrespective of their absolute molecular immunogenicity and used as vaccines to stimulate a protective immune response in mammalian hosts against subsequent infection by the target pathogen. The majorly abundant extracellular products may be characterized and distinguished by their respective N-terminal amino acid or DNA sequences. As the vaccines may comprise different combinations of the extracellular products, subunits thereof, or encoding nucleic acids, a broad range of effective immunotherapeutic compositions are provided by the present invention. In addition to other infectious agents, the vaccines so produced can be used to stimulate an effective immune response against intracellular pathogens and in particular Mycobacterium tuberculosis.

摘要:
The invention relates to recombinant polypeptides and peptides and particularly to the polypeptide containing in its polypeptidic chain the following amino acid sequence: the one extending from the extremity constituted by nucleotide at position (1) to the extremity constituted by nucleotide at position (194) represented in FIG. 4a and FIG. 4b. The polypeptides and peptides of the invention can be used for the diagnostic of tuberculosis, and can also be part of the active principle in the preparation of vaccine against tuberculosis.
