Claims
- 1. A purified and isolated nucleic acid encoding D29 mycobacteriophage having the sequence of SEO ID NO: 1.
- 2. A shuttle phasmid comprising a D29 mycobacteriophage which contains an E. coli bacteriophage lambda cosmid inserted into a non-essential region of said D29 mycobacteriophage.
- 3. The shuttle phasmid of claim 2 wherein said cosmid is excised by PacI.
- 4. The shuttle phasmid of claim 2, deposited under ATCC Accession No. 97468 and designated phAE70.
- 5. The shuttle phasmid of claim 2 further comprising a DNA of interest inserted into said E. coli bacteriophage lambda cosmid.
- 6. The shuttle phasmid of claim 3, that replicates at a temperature of 30.degree. C., but not at 37.degree. C.
- 7. The shuttle phasmid of claim 5, wherein said DNA of interest is a transposon.
- 8. The shuttle phasmid of claim 5, wherein said DNA of interest encodes a protein or polypeptide selected from the group consisting of: antigens, enzymes, lymphokines, immunopotentiators, selectable markers and reporter molecules.
- 9. A recombinant mycobacterium which expresses a DNA of interest introduced into its chromosome by the shuttle phasmid of claim 5.
- 10. An auxotrophic mutant produced by infecting a mycobacterium with the shuttle phasmid of claim 7, such that said transposon incorporates randomly or site-specifically into the genome of said mycobacterium thereby generating an auxotrophic mutant.
- 11. A method for producing a mutant mycobacterium comprising infecting a mycobacterium with the shuttle phasmid of claim 9 under conditions such that said transposon randomly or site-specifically inserts itself into the genome of said mycobacterium, thereby generating a mutation in said mycobacterium.
- 12. The recombinant mycobacterium of claim 9, wherein said DNA of interest encodes one or more proteins or polypeptides selected from the group consisting of: antigens, enzymes, lymphokines, immunopotentiators, selectable markers and reporter molecules.
- 13. The recombinant mycobacterium of claim 9, wherein said DNA of interest is a transposon.
- 14. The recombinant mycobacterium of claim 9, which is M. tuberculosis, M. bovis, BCG, or M. avium.
- 15. The auxotrophic mutant of claim 10 which is M. tuberculosis, M. bovis, BCG, or M. avium.
