Antimicrobial activities of different antibacterial peptides to the different bacteria. The different species of bacteria, including Escherichia coli (A), Salmonella typhimurium (B), Haemophilus parasuis (C) and Staphylococcus aureus (D), were used to test the antimicrobial activities of different antibacterial peptides. The optical density (OD₆₀₀) values of the bacterial cultures reflect the antimicrobial activities of the antimicrobial peptides. The data are shown as means±standard deviation, and representative of three independent experiments. * p<0.05; ** p<0.01.
