Fig. 4From: In-vitro antibacterial activity and mechanism of Monarda didyma essential oils against Carbapenem-resistant Klebsiella pneumoniaeEffects of MDEO on CRKP biofilm formation. Absorbance of CRKP biofilm treated by different MDEO concentration at 570 nm (A), crystal violet staining of CRKP biofilms treated with different concentrations of MDEO (B). Values represent the means of triplicate measurements. Bars represent the standard deviation (n = 3). *P ≤ 0.05, #P ≤ 0.05, **P ≤ 0.01Back to article page
