Figure 2.

Antibacterial activities of 6 synthesized peptides against five important pathogenic bacteria isolated from birds. In each experiment, respective bacterial species (from 10⁴ to 10⁵ CFU/ml) were incubated for 2 h with peptide concentrations ranging from 1.875 to 240 µg/ml in duplicate, serially diluted, and plated on agar media. The data is shown as mean ± SD of at least two independent experiments on different days.
