Fluorescence of the ethidium bromide in Salmonella Enteritidis. Intracellular accumulation of ethidium bromide in Salmonella Enteritidis pretreated with bailahuen and cedron. Salmonella Enteritidis were incubated in 96-well plates with vehicle (control) or 1 or 2 mg/ml of bailahuen or cedron extract; then, each was measured every 5 minutes for 50 minutes at 520 and 590 nm of excitation and emission, respectively. The data are shown as percentage of control (; ). The values indicate significant differences, .
