Identification of cytoplasmic membrane protein antigens of Mycobacterium avium, M. intracellulare, and M. scrofulaceum.
The cytoplasmic membrane isolated from representative strains of the Mycobacterium avium, M. intracellulare, and M. scrofulaceum (MAIS) group contained approximately 20 proteins, as identified by SDS - polyacrylamide gel electrophoresis. One membrane protein predominated, comprising up to 50% of the total membrane protein. This major cytoplasmic membrane protein (MCMP) had a molecular weight of...
متن کاملRestriction endonuclease analysis of members of the Mycobacterium avium-M. intracellulare-M. scrofulaceum serocomplex.
Organisms belonging to the Mycobacterium avium-M. intracellulare-M. scrofulaceum (MAIS) serocomplex were subjected to restriction endonuclease analysis (REA) with the enzymes BstEII, PvuII, and BclI. Substantial genetic heterogeneity was observed between members of an authenticated collection of the 31 serotypes. Serotypes 2 and 3 were indistinguishable, however, as were serotypes 5 and 10. No ...
متن کاملDisparate host immunity to Mycobacterium avium subsp. paratuberculosis antigens in calves inoculated with M. avium subsp. paratuberculosis, M. avium subsp. avium, M. kansasii, and M. bovis.
The cross-reactivity of mycobacterial antigens in immune-based diagnostic assays has been a major concern and a criticism of the current tests that are used for the detection of paratuberculosis. In the present study, Mycobacterium avium subsp. paratuberculosis recombinant proteins were evaluated for antigenic specificity compared to a whole-cell sonicate preparation (MPS). Measures of cell-med...
متن کاملSelective medium for the isolation and enumeration of Mycobacterium avium-intracellulare and M. scrofulaceum.
A medium for the selective isolation and enumeration of Mycobacterium avium-intracellulare and M. scrofulaceum (MAIS) was developed, based upon the ability of these mycobacteria to utilize Tween 80 as sole carbon source and grow optimally at pH 5.5 on a simple mineral salts medium. Representative MAIS strains had higher efficiencies of plating on the Tween 80 medium compared with Middlebrook 7H...
متن کاملModification of Schaefer's procedure for serotyping of organisms of the Mycobacterium avium-M. intracellulare-M. scrofulaceum complex.
Modifications to the tube-agglutination procedure which Schaefer developed for serotyping of organisms of the Mycobacterium avium-M. intracellulare-M. scrofulaceum complex are proposed.
