    摘要: This invention relates to the protein, Mycobacterium paratuberculosis acylase (mpa) and the gene encoding mpa, which we have identified in the pathogen Mycobacterium paratuberculosis Mptb (also designated Mycobacterium avium subspecies paratuberculosis MAP), and to their use in the diagnosis of Mptb/MAP infections in animals and humans, as well as their use as components of vaccines for the prevention and treatment of diseases caused by Mptb/MAP. The importance of an intact uninterrupted mpa gene as a determinant of pathogenicity in Mptb/MAP is recognized and the invention also provides attenuated strains of normally pathogenic Mptb/MAP and other mycobacteria in which mpa has been inactivated, for use as vaccines.

    摘要: A mutated mycobacterium selected from the class consisting of mutated M.bovis-BCG, mutated M.tuberculosis, and mutated M. leprae. The mutation of M.bovis-BCG, M.tuberculosis, or M. leprae is preferably effected through an insertional mutation of a mycobacterial gene. The insertional mutagenesis may be effected, for example, through illegitimate recombination or by a mycobacterial transposon. Such mutated mycobacteria may then be transformed with an expression vector(s) containing a complement gene to the gene which is mutated, and preferably also including a heterologous gene.

    摘要: An interspecific antigen of Mycobacteria consists essentially of a mixture in substantially immunochemically pure form of a protein having a molecular weight of at least about 4.times.10.sup.6 Daltons and polysaccharide having a molecular weight of at least about 1.times.10.sup.6 Daltons, and has when subjected to cross-electrophoresis an immunoelectrophoretic precipitation pattern corresponding to A60-antigen of Mycobacteria bovis strain BCG. This antigen is effective for detecting the prior exposure of a subject to Mycobacterial infections by a cutaneous test.

    摘要: The invention relates to the nucleic acid sequence and amino acid sequence of dihydrofolate reductase (DHFR) from mycobacteria and to expression of recombinant DHFR protein. Utilizing the recombinant protein, novel therapies and diagnostic strategies can be developed and selective antimycobacterial compositions can be designed and utilized to treat mycobacterial infections in patients. This invention includes all or portions of novel recombinant nucleic acids encoding DHFR for mycobacteria such as M. avium, to novel recombinant DHFR peptides produced by such sequences, and to vaccines, diagnostic kits, cells and therapies utilizing these peptides and nucleic acid sequences. The present invention relates to methods for using the sequences of the present invention to develop drugs specific to M. avium and other mycobacteria, to identify and sequence corresponding sequences in species other than M. avium, as well as diagnostic and treatment methods incorporating the disclosed sequences and peptides.
