Fibrinogen-Induced Streptococcus mutans Biofilm Formation and Adherence to Endothelial Cells

Table 1

Effect of human fibrinogen (5 mg mL⁻¹) added to THB-HK medium on biofilm formation by various strains of S. mutans. Results are expressed as means ± standard deviations of triplicate assays. ^∗𝑃<0.01: significantly different from the control (without fibrinogen).
