Fig. 1From: Importance of sigma factor mutations in increased triclosan resistance in Salmonella TyphimuriumFluorescence decreases at high concentrations of triclosan indicating higher efflux. High level of fluorescence of TDTU3C is observed at triclosan concentrations of 0,5 μg/ml (a) and 5 μg/ml (b) indicating low efflux of EtBr. Low fluorescence is seen at triclosan concentrations of 500 μg/ml (c) and 1000 μg/ml (d) indicating high efflux. Concentration of ethidium bromide is 1 μg/mlBack to article page
