Study of the development of microbial biofilm within an experimental model, Galleria mellonella
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...
