Abstract

The effect of low concentration of EDTA on bio?lm formation of Staphylococcus aureus was studied.The results showed that 0.2 mmol/L EDTA could effectively inhibit bio?lm formation of Staphylococcus aureus.EDTA could only influence the early stages of biofilm formation of Staphylococcus aureus.The inhibition of biofilm with EDTA could not be completely blocked by Ba2+,but it could be blocked by Fe2+,Ca2+,and Mg2+.Even high concentrations of EDTA could not influence the mature biofilm.EDTA could inhibit the adhesion between cells.

Key words： EDTA; Staphylococcus aureus; biofilm
