Charles University Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Study program: Pharmacy Author: Veronika Drgoňová Supervisor: PharmDr. Ondřej Janďourek, Ph.D. Consultant: Mgr. Martin Schwarzer, Ph.D. Title of diploma: Impact of selected probiotic bacteria on juvenile host growth in gnotobiotic mouse model This thesis expands understanding of the ability of Lactiplantibacillus plantarum WJL bacteria to support the growth of gnotobiotic hosts in models of chronic malnutrition. It was investigated whether other bacteria also have similar capabilities and whether these traits are species- and strain-specific. Strains of Bifidobacterium longum ssp. longum and Bifidobacterium adolescentis were tested in a gnotobiotic juvenile mouse model of chronic malnutrition and their impact on the host's somatotropic axis was monitored. Concurrently, it was analysed how malnutrition affects the bacteria in the host's gut and the level of its colonization. Germ-free C57BL/6J mice were mono-colonized via intragastric gavage with the aforementioned bacterial strains. The mice were mated after confirming stable colonization and F1 male offspring were weaned on the 21st day after birth onto an experimental diet with low protein and fat content. Their growth was monitored weekly by...

Doubová, Dominika ; Konečná, Klára (advisor) ; Janďourek, Ondřej (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Candidate: Dominika Doubová Supervisor: RNDr. Klára Konečná, Ph.D. Title: Study of the development of microbial biofilm within an experimental model, Galleria mellonella Aim of the thesis: The aim of this thesis is to introduce the invertebrate organism, Galleria mellonella (G. mellonella), that can be used within the scientific research as an alternative model organism to vertebrates. This model seems to be more financially favorable and more ethically acceptable, which is an essential fact in the current era of increasing pressure to abandon testing on vertebrates in particular. The experimental part of this thesis is focused on optimizing the utilization of the G. mellonella larvae as a model organism within the research of fungal burn wounds fungal infections induced by the yeast Candida albicans. Within these experiments, larvae were used to preparation of tissue explants on which the formation of a single- species yeast biofilm was investigated. Methods: Before obtaining of tissue explants, the larvae were decapitated. To reduce contamination of tissue samples primarily by the gut microbiota of the larvae, the approach of removing the digestive tube was optimized. Burn wounds were induced...

6 ABSTRACT Charles university, Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Study program: Pharmacy Author: Veronika Záveská Supervisor: RNDr. Klára Konečná, Ph.D. Title of thesis: Study of in vivo toxicity of selected compounds with the implementation of the invertebrate model Galleria mellonella Background: The aim of this diploma thesis was to monitor the influence of the weight of the larvae, or rather its developmental stage, on the results after the administration of selected doses of DMSO. In the experimental work, the toxic impact of DMSO on larvae was evaluated not only from the point of view of mortality. Much attention was also paid to the characteristic features that are commonly observed during tests on Galleria mellonella larvae, such as the degree of melanization, the impact on activity and cocoon formation. Methods: For individual experiments, three test groups of six individuals each were created based on weight, one group of larvae weighing 250 ± 10 mg, the second group weighing 350 ± 15 mg and the third group weighing 450 ± 15 mg. Using a Hamilton syringe, a volume of 10 µl of the test solution with the appropriate concentration of DMSO was administered to each larva directly into the haemocoel through the last left proleg. The administered doses...

Charles University, Faculty of Pharmacy in Hradec Králové Study programme: Pharmacy Candidate: Markéta Lanková Supervisor: PharmDr. Ondřej Janďourek, Ph.D. Title of diploma thesis: Mycobacterial resistance against currently used antimycobacterial drugs Keywords: Mycobacteria, Mycobacterioses, Resistance, Antimycobacterials, Microdilution broth method, Minimum inhibition concentration The successful treatment of mycobacterial diseases is nowadays often confronted with the declining effect of antituberculotics and other antimicrobial agents, which are often used in the therapy of mycobacterial diseases. The goal of the theoretical part of the thesis was to focus on a comprehensive assessment of the issue of resistance to the current therapeutics used in the fight against resistant mycobacterial strains, to summarize the basic characteristics of the genus Mycobacterium, to address resistant TBC and NTM, and to describe the mechanisms of action and resistance known so far for individual therapeutics, which are often interrelated. The emergence of highly resistant mycobacterial strains is constantly increasing the risk of serious, life-threatening infections. The mechanisms of resistance either arise from the natural properties of the cell or develop gradually as a result of external stimuli, which is...
