  1. 1. 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

  2. 2. Antibiotic Resistance : Selection in the Presence of Metals and Antimicrobials

    Author : Lisa M. Albrecht; Dan I Andersson; Alex O'Neill; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antibiotic resistance; Metals; Antimicrobials; Bacterial evolution; Bacterial genetics; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : The external environment is complex: Antibiotics, metals and antimicrobials do not exist in isolation but in mixtures. Human activities such as animal husbandry, fertilization of agricultural fields and human medicine release high amounts these compounds into the environment. READ MORE

  3. 3. 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

  4. 4. Antibiotic resistance in the environment: a contribution from metagenomic studies

    Author : Johan Bengtsson-Palme; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; antibiotic resistance; metagenomics; bioinformatics; next generation sequencing; resistance selection;

    Abstract : Antibiotic resistance accounts for hundreds of thousands of deaths annually, and its projected increase has made the WHO recognize it as a major global health threat. In the last decade, evidence has mounted suggesting that the environment plays an important role in the progression of resistance. READ MORE

  5. 5. 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.
