From: Crippling of Klebsiella pneumoniae virulence by metformin, N-acetylcysteine and secnidazole
Inhibition of biofilm formation in K. pneumoniae by a) metformin, b) NAC, and c) secnidazole. A significant reduction of biofilm formation was found with 1/8 MIC of metformin, NAC, and secnidazole in the treated isolate in comparison with the untreated isolate. Biofilm formation was measured by staining with crystal violet and the OD570 was measured. The results were expressed as percentage of OD. The data shown represents the means ± standard errors. One WAY ANOVA test was used for statistical analysis. *, significant P < 0.05 was considered significant
