Effect of peptide BP178 on viability of Xff strain Temecula estimated by v-qPCR at different peptide concentrations (1.6, 12.5 and 50 μM). Two assays were performed at different initial Xff cell concentrations, 1 × 107 CFU/ml (circles) and 1 × 108 CFU/ml (squares). The exposure time to the peptide was 3 h. Xff concentration in non-treated cells was estimated after 3 h by v-qPCR. The detection limit of the v-qPCR is 3 log CFU/ml. Values are the means of three replicates, and error bars represent the standard deviation of the mean. Lowercase letters correspond to the means comparison of viable cells in 1 × 107 CFU/ml. Capital letters correspond to the means comparison of viable cells in 1 × 108 CFU/ml. Means sharing the same letters are not significantly different (P < 0.05), according to the Tukey’s test
