Optimization of treatment protocols to prevent de novo development of antibiotic resistance in Pseudomonas aeruginosa

The ever-increasing rate of drug resistant bacteria has been one of the most challenging problem worldwide. This thesis studied the following subjects with mostly the clinically leading pathogen, P. aeruginosa, as the model strain: de novo development of antibiotic resistance in patient during the treatment, the influences of the therapy failure of an initial antibiotic treatment on the therapeutic effects of subsequent treatments, the dynamics of mutations during development of resistance by bacteria against the commonly used antibiotics in hospitals, and the optimal ways to administrate drugs in order to cure the infection and at the same time maximally reduce the occurrence of antibiotic resistance.
