Studies on Antimicrobial Resistance in Pathogenic Bacteria

Jelínková, Pavlína

Bacterial infections caused by pathogenic microorganisms are classified among one of the major global health problems. In recent decades, bacterial resistance to antimicrobials has been seen as a major problem in the human and veterinary fields. The dissertation thesis is focused on the development and evaluation of the biological activity of antimicrobial agents, followed by describing the mechanism of antibiotic resistance from a molecularly microbiologically aspects. In the experimental part the nanomaterials, antimicrobial peptides, antibiotics and also the composites from these materials have been used for development of new antimicrobial agents and subsequently tested for their inhibitory effect on bacterial growth. The synthesized antimicrobials were physically and chemically characterized and their biological activity was established by basic microbiological and molecular methods. The results show that the produced composites can overcome existing drug resistance mechanisms, show excellent biocompatibility, and can be used in clinical practice in the future.
