The intracellular growth kinetics ofMycobacterium avium and H37Rv (virulent) and H37Ra (avirulent) strains ofMycobacterium tuberculosis were compared by use of both the professional (mouse bone marrow-derived macrophages, BMMØ) and nonprofessional (mouse L-929 fibroblast cell line) phagocytes. The results obtained showed that all the mycobacterial strains grew more actively in fibroblasts than in BMMØ. This difference was paralleled by lesser acid phosphatase (AcP) labeling of noninfected… CONTINUE READING
