Summary:ObjectiveTo study bactericidal effect of ultraviolet A – light emitting diode (UVA-LED) irradiation combined with phytochemical of allyl isothiocyanate (AITC) on two diarrhea-causing pathogens. MethodsTwo diarrhea-causing pathogenic bacteria, enteropathogenic Escherichia coli (ETEC) and Vibrio parahaemolyticus (VP), were used as the subjects. Bactericidal experiments in 3 × 2 factorial design were performed with the combined treatment of different concentrations of AITC and UVA365 nm-LED irradiation; and the bacteria survival was assessed with colony form unit (CFU) and logarithm value of survival rate was calculated. The interactive effect of AITC and UVA365 nm-LED irradiation was evaluated with analysis of variance for factorial design and illustrated with schematic diagram. ResultsThe bactericidal effect of AITC alone was gradually increased with the increment of concentration (P < 0.05). The effect of the combination of UVA-LED irradiation with AITC on the two pathogenic bacteria were statistically signif
