Abstract: Mycobacterium avium subspecies paratuberculosis, a slow-growing Mycobacterium, is the causative agent of Johne's disease. Although M. paratuberculosis is difficult to manipulate genetically, our laboratory has recently demonstrated the ability to introduce DNA into these bacteria by transformation and phage infection. In the current study we develop the first transposon mutagenesis system for M. paratuberculosis using the conditionally replicating mycobacteriophage phAE94 to introduce the mycobacterial transposon Tn5367. Southern blotting and sequence analysis demonstrated that the transposon insertion sites are distributed relatively randomly throughout the M. paratuberculosis genome. We constructed a comprehensive bank of 5620 insertion mutants using this transposon. The transposition frequency obtained using this delivery system was 1.0 x 10(-6) transposition events per recipient cell. Auxotrophic mutants were observed in this library at a frequency of 0.3%.

Abstract: The invention relates to a nucleotide sequence which is present at a position adjacent to the 5' end of the reverse sequence complementary to the open reading frame coding for a potential transposase contained in the insertion element IS900 in Mycobacterium paratuberculosis. The nucleotide sequence has promoter functions and contains important signals for the regulation of transcription and translation. The invention also relates to methods for cloning and expressing heterologous proteins using such regulatory sequences, to vectors and transformed host cells containing these sequences, and to immunogenic compositions prepared by expression of nucleotide sequences placed under control of these regulatory sequences.

Abstract: Mycobacterium avium subsp. paratuberculosis infection of cattle results in a chronic granulomatous enteritis. Clinical disease (i.e. cachexia, diarrhea and high fecal bacterial counts) is preceded by a lengthy subclinical stage of disease. The immunologic mechanisms associated with the progression of infected cattle from subclinical to clinical disease are unclear. In this study, a cell proliferation assay was used in combination with flow cytometry to compare peripheral blood lymphocyte responses of cattle with subclinical paratuberculosis to responses of cattle with clinical paratuberculosis. B cells from cattle with subclinical disease proliferated vigorously upon stimulation with M. avium subsp. paratuberculosis antigen, with up to 12.4% of the total B cells responding. However, B cells from cattle with clinical disease did not proliferate upon antigen stimulation despite good proliferation in response to concanavalin A stimulation. In addition, these animals had high percentages of peripheral blood B cells. B cells from noninfected animals did not proliferate upon M. avium subsp. paratuberculosis antigen stimulation. Thus, it appears that B-cell proliferation is a sensitive indicator of subclinical Johne's disease. Furthermore, the immunologic mechanisms responsible for the antigen-specific unresponsiveness of peripheral blood B cells may be significant in the eventual progression from subclinical to clinical Johne's disease in cattle.
