Three-dimensional low shear culture of Mycobacterium bovis BCG induces biofilm formation and antimicrobial drug tolerance

ABSTRACT: Mycobacteria naturally grow as corded biofilms in liquid media without detergent. Such detergent-free biofilm phenotypes may reflect the growth pattern of bacilli in tuberculous lung lesions. New strategies are required to treat tuberculosis that is responsible for more deaths each year than any other bacterial disease. The lengthy six-month regimen for drug-sensitive tuberculosis is necessary to remove antimicrobial drug tolerant populations of bacilli that persist through drug therapy. The role of biofilm-like growth in the generation of these sub-populations remains poorly understood despite the hypothesized clinical significance and mounting evidence of biofilms in pathogenesis. We adapted a three-dimensional Rotary Cell Culture System to model M. bovis BCG biofilm growth in low-shear
