Fig. 1From: The drug tolerant persisters of Riemerella anatipestifer can be eradicated by a combination of two or three antibioticsTime-dependent killing by test antibiotics alone. Exponential cells of RA 11845 and RA TQ3 were treated with different concentrations of ceftiofur (a), ciprofloxacin (b) and spectinomycin (c), respectively. RE presents RA reference strain, RA 11845; TQ3 presents RA clinical isolate, RA TQ3. The detection limit was 102Â CFU/ml. Each spot showing on the figure was the mean of three biological replicates. The error bars represent the standard deviation of the meanBack to article page
