  2. 6. CopA and CopT: The Perfect RNA Couple

    Author : Jacoba G. Slagter-Jäger; Gerhart Wagner; Wolfgang Nellen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; antisense RNA; plasmid; U-turn; four-way junction; RNA-RNA interaction; Hfq; Mikrobiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

    Abstract : Antisense RNAs regulate gene expression in many bacterial systems. The best characterized examples are from prokaryotic accessory elements such as phages, plasmids and transposons. Many of these antisense RNAs have been identified as plasmid copy number regulators where they regulate the replication frequency of the plasmid by negative feedback. READ MORE

  5. 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.

  6. 9. Antibiotic interactions and selection for resistance in biofilms

    Author : Po-Cheng Tang; Dan I. Andersson; Karin Hjort; Mark Webber; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibiotics; Mikrobiologi; Microbiology;

    Abstract : The challenges posed by antibiotic-resistant bacteria in treating infections, particularly those associated with biofilms, require a deeper understanding of this lifestyle and its connection to resistance selection. Additionally, gaining insights into drug interactions is crucial for enhancing combination treatment efficacy and mitigating resistance development. READ MORE

  7. 10. Antibiotic Resistance in Wastewater : Methicillin-resistant Staphylococcus aureus (MRSA)and antibiotic resistance genes

    Author : Stefan Börjesson; Per-Eric Lindgren; Johanna Ericson Sollid; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MRSA; SCCmec; spa typing; Staphylococcus aureus; methicillin; B-lactam; aminoglycoside; tetracycline; antibiotic; wastewater; wastewater treatment plant; Microbiology; Mikrobiologi;

    Abstract : A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. Antibiotic resistant bacteria and genes encoding antibiotic resistance are commonly detected in wastewater, often at higher rates and concentrations compared to surface water. READ MORE
