2. 1. Dynamics of the Bacterial Genome : Rates and Mechanisms of Mutation

   Author : Sanna Koskiniemi; Dan Andersson; Diarmaid Hughes; Ivan Matic; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteria; bacterial evolution; genome reduction; gene loss; serial passage; DNA homology; tranlesion DNA polymerase; stress; Microbiology; Mikrobiologi; Bacteriology; Bakteriologi; Evolutionary Genetics; Evolutionär genetik; Mikrobiologi; Microbiology;

   Abstract : Bacterial chromosomes are highly dynamic, continuously changing with respect to gene content and size via a number of processes, including deletions that result in gene loss. How deletions form and at what rates has been the focus of this thesis. In paper II we investigated how chromosomal location affects chromosomal deletion rates in S. READ MORE

4. 2. Nutrient Limitation of Bacterial Growth in Soil

   Author : Fredrik Demoling; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ekologi; Ecology; Fertilization; Bacteria; Soil; Fungi; Thymidine or Leucine incorporation; Growth limitation; Phosphorus; Nitrogen; Carbon;

   Abstract : Lack of carbon has been assumed to be the most common limiting factor for bacterial growth in soil, although there are reports of limitation by nitrogen and phosphorus. I have studied nutrient limitation of bacterial growth in soil using a novel technique, where thymidine or leucine incorporation is used to detect changes in growth rates after adding nutrients.

5. 3. Interaction of cyclotides and bacteria : A study of the cyclotide action and the bacterial reaction

   Author : Sohaib Zafar Malik; Ulf Göransson; Dan Andersson; William Shafer; Uppsala universitet; []
   Keywords : Cyclotides; cycloviolacin O2; cycloviolacin O3; cycloviolacin O19; antimicrobial peptide resistance; Salmonella enterica; Eschericia coli; Viola odorata; Farmakognosi; Pharmacognosy;

   Abstract : The growing problem of antibiotic resistance and the lack of promising prospective antibiotics have forced us to search for new classes of antibiotics. Among the candidates to develop into future antibacterials are antimicrobial peptides (AMPs). READ MORE

6. 4. Dynamic Organization of Molecular Machines in Bacteria

   Author : Bhupender Singh; Santanu Dasgupta; Leif A. Kirsebom; Don G. Ennis; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular machines; bacteria; cell cycle; ribosome; replisome; divisome; spore; E. coli; H. pylori; Mycobacteria; Microbiology; Mikrobiologi; Mikrobiologi; Microbiology;

   Abstract : Bacterial cells were once treated as membrane-enclosed bags of cytoplasm: a homogeneous, undifferentiated suspension in which polymers (proteins, nucleic acids, etc.) and small molecules diffused freely to interact with each other. READ MORE

7. 5. Disarming bacteria : a structure-based approach to design an anti-virulence drug against Listeria monocytogenes

   Abstract : Antibiotic resistances are one of the biggest threats to global health and if we don’t change our behavior and way of using antibiotics we will end up in a ‘post-antibiotic era’, in which common infections and minor injuries can once kill again and up to 10 million deaths per year may occur by 2050. Therefore, there is a high need for new anti-bacterial drugs, especially of alternatives to existing antibiotics with already described resistances. READ MORE
