Abstract
Antimicrobial peptides are essential components of the innate immunity of all animal species. These peptides have a broad range of activity against resistant microorganism strains primarily because of their distinct mechanisms of action. Several groups are currently developing synthetic and / or variant peptides as new therapeutic drugs against specific pathogens.
