Antivirotické a antibakteriální účinky biologicky aktivních látek z přírodních zdrojů a jejich potenciální využití proti klíšťaty přenášeným patogenům
 LUDVÍKOVÁ, Nikola
The first aim of this study was to detect antiviral activities of substances isolated from natural products against tick-borne encephalitis virus in in vitro model. Resveratrol isolated from plant material and adamantane derivatives were studied in this regard. The maximum tolerated concentrations of the investigated substances were determined for the glioblastoma cell line used in the experiments using flow cytometry and subsequently. Next, the number of viral particles produced by infected cells after incubation with the studied substances was determined using plaque titration. Possible antibacterial effects of the studied materials against standard strains of bacteria Staphyloccocus aureus, Staphyloccocus epidermidis, Escherichia coli and selected strains of Borrelia burgdorferi spirochetes were examined.

Antivirotické účinky stilbenoidů proti klíšťaty přenášeným patogenům in vivo
 MAŠKOVÁ, Hana
This study was focused on antiviral effects of stilbenoids against a virus transmitted by ticks. The cell viability of selected cell line cultures in the presence of various concentrations of stilbenoids was determined using the MTT assay. Similarly, the mixed effect of other known antiviral substances and stilbenoids was studied using the MTT assay. Both the prophylactic effects of stilbenoids on the infected culture cell lines and the effect on viral replication were examined. The viral titres from samples were determined using plaque assay. Some of the experiments were performed also in vivo using laboratory mice.
