Influence of antibacterial enzymes on preparation and properties of phosphate cements
Přečková, Barbora ; Michlovská, Lenka (oponent) ; Vojtová, Lucy (vedoucí práce)
The subject of the bachelor thesis is to prepare tricalcium phosphate bone cement (CPC) modified with antibacterial enzyme for effective and safe bone infection (osteomyelitis) treatment in comparison to antibiotics therapy. The theoretical part of this bachelor thesis provides informations about the structure of bone, osteomyelitis and treatment of osteomyelitis by different types of antibacterial bone cements, specifically by calcium phosphate bone cements. The experimental part deals with optimization in sample preparation, description of the used methods and characteristics of enzyme release kinetics from the cured CPC. To better understand the enzyme release mechanism from the cement, model both enzyme and protein-loaded CPC samples were also prepared and evaluated. Antibacterial properties of the prepared samples were tested by disk-diffusion, dilution and plate method resulting in the positive inhibition effect of antibacterial enzyme on Gram-positive bacteria (G+) of Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) strains but negligible effect on Gram-negative bacteria (G-) Escherichia coli. In the following work, the in vitro biocompatibility of the enzyme-loaded cements will be evaluated.
