FIG 1.

Inhibition of APEC growth by peptides P1 (A), P2 (B), P3 (C), and P4 (D) at different concentrations. Peptides were added to the wells of a 96-well plate containing APEC suspension and incubated at 37°C in a TECAN Sunrise absorbance microplate reader with kinetic absorbance measurement set at every 30 min for 12 h. The inhibition (%) was calculated using the formula (OD₆₀₀ of the DMSO-treated well − OD₆₀₀ of the peptide-treated well)/OD₆₀₀ of the DMSO-treated well × 100. Two independent experiments were conducted.
