  1. 6. Antibiotic Resistance: A Multimethod Investigation of Individual Responsibility and Behaviour

    Author : Mirko Ancillotti; Stefan Eriksson; Jessica Nihlén Fahlquist; Dan I. Andersson; Alberto Giubilini; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotic resistance; Behavior; Health Behavior; Health Belief Model; Discrete Choice Experiment; Preferences; Bioethics; Empirical bioethics; Moral responsibility; Justice; Policy demandingness; Virtue ethics; Bioetik; Bioethics;

    Abstract : The rapid development of antibiotic resistance is directly related to how antibiotics are used in society. The international effort to decrease and optimise the use of antibiotics should be sustained by the development of policies that are sensitive to social and cultural contexts. READ MORE

  2. 7. Experimental Evolution : and Fitness Effects of Mutations

    Author : Anna Knöppel; Dan I Andersson; Stanley Maloy; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Experimental evolution; Fitness effects; mutations; S20; fis; ribosome; horizontal gene transfer; adaptation; synonymous mutations; Mikrobiologi; Microbiology;

    Abstract : Bacteria have small, streamlined genomes and evolve rapidly. Their large population sizes allow selection to be the main driver of evolution. With advances in sequencing technologies and precise methods for genetic engineering, many bacteria are excellent models for studying elementary questions in evolutionary biology. READ MORE

  3. 8. Evolutionary Dynamics of Mutation and Gene Transfer in Bacteria

    Author : Peter A Lind; Dan I Andersson; J. Arjan G. M. de Visser; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fitness cost; bacterial evolution; gene amplification; mutational biases; GC content; synonymous substitutions; horizontal gene transfer; experimental evolution; Bacteriology; Bakteriologi; Microbiology; Mikrobiologi; Genetics; Genetik; Biology; Biologi; Mikrobiologi; Microbiology;

    Abstract : The study of bacterial evolution is fundamental for addressing current problems of antibiotic resistance and emerging infectious diseases and lays a solid foundation for successful and rational design in biotechnology and synthetic biology. The main aim of this thesis is to test evolutionary hypotheses, largely based on theoretical considerations and sequence analysis, by designing scenarios in a laboratory setting to obtain experimental data.

  4. 9. Evolution of New Genes and Functions

    Author : Erik Lundin; Dan I Andersson; Joakim Näsvall; Diarmaid Hughes; Arjan de Visser; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : To answer major evolutionary questions, we need a better understanding of the effects of mutations on specific functions and organism fitness. The aim of this thesis was to elucidate how new functions evolve and potential trade-offs with the original function. READ MORE

  5. 10. Evolution and host-specific adaptations of Legionella pneumophila

    Author : Anaísa B. Moreno; Lionel Guy; Dan I. Andersson; Fredrik Söderbom; Alexander W. Ensminger; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Evolution; Legionella pneumophila; host-adaptation; experimental evolution; Acanthamoeba castellanii; transfection; Mikrobiologi; Microbiology;

    Abstract : How bacteria evolve pathogenic traits is shaped by their communities and environments. Legionella pneumophila is ubiquitous in aquatic habitats, where it persists by replicating within a broad range of protozoan hosts. Using the same mechanisms, L. READ MORE
