21. Dynamics and Mechanisms of Adaptive Evolution in Bacteria
Abstract : Determining the properties of mutations is fundamental to understanding the mechanisms of adaptive evolution. The major goal of this thesis is to investigate the mechanisms of bacterial adaptation to new environments using experimental evolution. READ MORE

22. Small RNAs, Big Consequences : Post-transcriptional Regulation and Adaptive Immunity in Bacteria
Abstract : It is nowadays widely accepted that non-coding RNAs play important roles in post-transcriptional regulation of genes in all kingdoms of life. In bacteria, the largest group of RNA regulators are the small RNAs (sRNAs). READ MORE

23. Exploration of bacteria associated with Anopheles mosquitoes around the world : For the prevention of transmission of malaria
Abstract : Every year, hundreds of thousands of people die from malaria. Malaria is a disease caused by parasites, which are spread by female vector mosquitoes of the genus Anopheles. Current control measures against malaria are based on drugs against the parasites and vector control using insecticides. READ MORE

24. Assembly of Gut Microbial Communities in Freshwater Fish and Their Roles in Fish Condition
Abstract : Animal hosts provide associated microorganisms with suitable ecological niches in their intestines. Microbes help their hosts to digest food, protect against pathogens, and influence the host’s metabolisms. Compositional variation of gut microbial communities is common among hosts, and may affect the health status of hosts. READ MORE

25. Selection of Resistance at very low Antibiotic Concentrations
Abstract : The extensive medical and agricultural use and misuse of antibiotics during the last 70 years has caused an enrichment of resistant pathogenic bacteria that now severely threatens our capacity to efficiently treat bacterial infections. While is has been known for a long time that high concentrations of antibiotics can select for resistant mutants, less is known about the lower limit at which antibiotics can be selective and enrich for resistant bacteria.
