activity against extremely drug resistant pathogens. Bacteria exposed to them do not develop resistance to these agents, and they are not toxic to mammalian cells. Activity was seen against salmonellosis and C. difficile infection in animal models.
Our results demonstrate that fatty acids coated with chitosan are effective antibiotics, and can be used for a long period of time without resistance developing. This suggests that the usage of fatty acids coated in this manner could be sold in sufficient quantities to recoup its development costs, overcoming this barrier. These agents would form a new class of antibiotics, with the novel property of lack of bacterial resistance.
