Effect of growth in biofilms on chlorine susceptibility of Mycobacterium avium and Mycobacterium intracellulare

Article Abstract:

Mycobacterium avium and Mycobacterium intracellulare were grown in suspension and in biofilms and their susceptibilities to chlorine were calculated. The results revealed that there was a strong correlation between the chlorine susceptibility of cells of both and cell surface hydrophobicity measured by contact angle for both bio-film and suspension growth cells.

Factors influencing the chlorine susceptibility of Mycobacterium avium, Mycobacterium intracellulare, and Mycobacterium scrofulaceum

Article Abstract:

The authors have investigated Mycobacterium avium, Mycobacterium intracellulare, and Mycobacterium scrofulaceum strains. They have studied the susceptibility of these strains to chlorine, and discuss the factors which are related to culture growth phase and which affect bacteria's chlorine susceptibility.

Fluorescent acid-fast microscopy for measuring phagocytosis of Mycobacterium avium, Mycobacterium intracellulare, and Mycobacterium scrofulaceum by Tetrahymena pyriformis and their intracellular growth

Article Abstract:

Phagocytic protozoa such as Tetrahymena pyriformis may act as reservoirs for mycobacteria. Using fluorescent acid-fast microscopy, researchers discovered that phagocytized mycobacteria continue to grow inside the protozoan and survive protozoal encystment and germination.
