Bacitracin and the polymyxins are polypeptide antibiotics. They are relatively toxic drugs and have had only limited use in chemotherapy until recently. Vancomycin, a glycopeptide, although not without side effects, is widely used. Teicoplanin is a new glycopeptide antibiotic that may be beneficial against certain infections caused by gram-positive organisms. The mechanisms of action of this group vary.
