In vitro bactericidal experiment of ai′erdian skin antiseptic on positive pathogenic bacteria

OBJECTIVE To study the minimum bactericidal concentration of ai′erdian skin antiseptic on positive pathogenic bacteria.METHODS All the pathogenic bacteria producing biofilm were tested,then different concentrations of ai′erdian skin antiseptic were applied to the biofilm-positive pathogens for difference period of time,the sterilization effects were observed.RESULTS The positive rates of the formation of biofilm of Staphylococcus aureus,Escherichia coli and Pseudomonas aeruginosa were 54.3%,47.3% and 57.0%;All of the positive pathogenic bacteria were eradicated with the effective content of iodine of 9.203×10-4 mg/L for 1min.CONCLUSION Ai′erdian skin antiseptic is a kind of strong and effective disinfectant on biofilm positive pathogenic bacteria.
