We identified peptides derived from human lactoferricin with potent antimicrobial activity against p aeruginosa growing either in small and amphipathic cationic peptides are promising anti-biofilm agents, not only due to their broad activity spectrum, rapid mechanism of action and less susceptibility.
Antimicrobial peptides have been found in various different organisms, such as amphibians, birds, insects, mammals, and even plants and in bacteria themselves they may be a part of an evolutionarily ancient system for immune defense over the past two decades, more than 1.

We recently reported that the human cationic antimicrobial protein hcap18, the precursor of the antimicrobial peptide called ll-37, is not expressed by normal our finding that hcap18 is widely produced in squamous epithelia suggests a role for this peptide in epithelial antimicrobial defense. Antimicrobial peptides (amps), also called host defense peptides (hdps) are part of the innate immune response found among all classes of life fundamental differences exist between prokaryotic and eukaryotic cells that may represent targets for antimicrobial peptides.
