Abstract

The invention relates to an anti-bacterial composition, especially for controlling gram-negative bacteria, containing a combination of: a) at least one peptide of between 10 and 25 amino acid residues comprising: i) two positively charged domains with a neutral pH consisting of between 3 and 9 amino acid residues, at least two thirds thereof being cationic amino acids, ii) a group of two to three non-cationic amino acid residues located between said positively charged domains, iii) a group of between 0 and 10, preferably between 0 and 5, amino acid residues selected from the group comprising non-hydrophobic amino acids and positively charged amino acids, located at one of the terminal ends N or C of the peptide, a positively charged amino acid residue, however, not being directly adjacent to the positively charged domains; and b) at least one anti-bacterial compound.
