Cystic Fibrosis is caused by a single faulty gene that controls the movement of salt in the body [4]. Another cause of AMR is the poor pharmacokinetics of many classical drugs, due to difficulty in reaching the site of action; as a result, subcellular niches used by infecting bacteria are not reached by most current drugs.
