Investigation of catalase and superoxide dismutase from Mycobacterium avium, M. intracellulare and M. scrofulaceum
… in cell-free extracts of Mycobacterium avium, M. intracellulare and M. scrofulaceum (MAIS). The M. scrofulaceum isolates had the highest catalase activity, while both M. avium and M. intracellulare had significantly lower activities. The percentage of catalase activity remaining, after exposing …

Soil as a possible origin of organisms of the Mycobacterium avium, M. intracellulare, and M. scrofulaceum (Mais) complex in southeastern United States
… of organisms of the Mycobacterium avium, M. intracellulare, and M. scrofulaceum (MAIS) complex. Their numbers in soil and water were compared to physiochemical characteristics of these samples. Further, the number of MAIS organisms recovered from acidified and alkalinized soil samples, …

Effect of growth in biofilms upon antibiotic and chlorine susceptibility of Mycobacterium avium and Mycobacterium intracellulare
Mycobacterium avium and Mycobacterium intracellulare are environmental opportunistic pathogens whose source for human infection is water and soil. M. avium and M. intracellulare cause pulmonary infections (tuberculosis) in immunocompetent individuals and bacteremia in immunodeficient individuals …

Insertion sequence IS1141: discovery, characterization, and association with Mycobacterium intracellulare colonial variation
Mycobacterium avium and Mycobacterium intracellulare, (M. avium complex, MAC) are human pathogens causing disease in individuals with acquired immunodeficiency syndrome (AIDS) or with thoracic abnormalities. MAC bacteria are difficult to kill because of the resistance of the pathogens to …

Action of clofazimine on Mycobacterium avium and Mycobacterium intracellulare
… the generation of superoxide radicals in M. intracellulare strain LR163 represented by cyanide-resistant oxygen consumption. The amount of oxygen consumed was dependant upon the clofazimine concentration. This supports the hypothesis that clofazimine is antibiotic via its ability to generate …

Relationship of plasmids in Mycobacterium avium, Mycobacterium intracellulare, and Mycobacterium scrofulaceum
Bacteria of the <i>Mycobacterium avium, M. intracellulare, and M. scrofulaceum</i> group (MAIS) are opportunistic human pathogens and widespread in the environment. The first objective of this study was to demonstrate that plasmids from clinical isolates are closely related to plasmids from …

Adherence and Biofilm Formation of Mycobacterium avium, Mycobacterium intracellulare, and Mycobacterium abscessus in household plumbing
… of NTM, Mycobacterium avium, Mycobacterium intracellulare, and Mycobacterium abscessus, were examined for adherence and biofilm formation on surfaces common to household plumbing systems, including glass, copper, stainless steel, polyvinyl chloride, and galvanized steel. All experiments were …

Survival strategies of Mycobacterium avium subsp. paratuberculosis in a variety of microenvironments.
… of M. avium subsp. avium (M. avium), MAP, M. intracellulare and M. avium subsp. hominissuis (M. hominissuis), all of which share an over 90 percent nucleotide similarity. Despite its genetic similarity, MAC elicits different diseases in both animals and humans including infections of the lung, …

Phylogenetic Analysis of the Mycobacteria and Diagnosis of Paratuberculosis by 16SrRNA Amplification and Probing
… the species distinction for M. avium and M. intracellulare, the identification of M. paratuberculosis as a variant of M. avium, and could not distinguish the mycobacterium isolated from a Crohn's patient from the M. avium group. The 16S rRNA database served for the design of a series of …

The Mycobacterium tuberculosis KatG gene : identification of a novel function and analysis of the regulation of expression
… in the macrophage. UV sensitivity tests on M intracellulare and M tuberculosis strains mutant in katG revealed that the katG gene product does not play a demonstrable role in the survival of repair-competent mycobacterial cells after exposure to UV irradiation. The second aim of this study was …

Genetic mechanisms contributing to antimicrobial resistance: gene repression in Mycobacterium, gene transfer in Salmonella, and phage sensitivity in Escherichia
… of efflux pump expression in Mycobacterium intracellulare, regulation mechanisms of natural competence in Salmonella Typhimurium, and phage therapy of Enterohemorrhagic Escherichia coli serogroup O157:H7. A recent study showed specific mutations in the uncharacterized locus mmpT5 increased …
