Effect of cyclosporine-A, acarbose or GaNP on induction of biofilm in M. smegmatis (Crystal violet assay). Ms_VC and Ms_PpiB cells were cultured in absence [()VC tet-, (
) PpiB tet-] or presence [(
) VC tet+, (
) PpiB tet+] of anhydrotetracycline, as described in methods. Cells were treated with cyclosporine-A (0, 10, 100, 1000 μg/ml) a or acarbose (0, 1, 10, 100, 500, 1000 μg/ml) b or GaNP (0, 10, 50, 100, 1000 μg/ml) c and incubated for 7 days. At the end point, biofilm was quantified as described in methods. Values shown from a representative experiment are means [±s.e.m] of biofilm formed.*p < 0.05, **p < 0.01, ***p < 0.005 (Student’s t test)
