Identification and characterization of a novel antimicrobial peptide from the venom of the ant Tetramorium bicarinatum

► First study describing the antibacterial activity of the venom of the Tetramorium bicarinatum ant against different referenced and wild Staphylococcus strains. ► The compound responsible for antibacterial activity is a novel amidated linear cationic peptide. ► This peptide, named Bicarinalin, is composed of 20 amino-acids and her sequence is totally original. ► Bicarinalin is weakly hemolytic, so it could be an interesting alternative drug.
