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

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Stefan Börjesson; Linköpings universitet.; Linköpings universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MRSA; SCCmec; spa typing; Staphylococcus aureus; methicillin; B-lactam; aminoglycoside; tetracycline; antibiotic; wastewater; wastewater treatment plant; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi 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 uptake in Gram-negative bacteria

    University dissertation from Department of Biochemistry and Biophysics, Stockholm University

    Author : Claudio Muheim; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gram-negative bacteria; Antibiotic uptake; Outer membrane; Lipopolysaccharide; biokemi; Biochemistry;

    Abstract : The increasing emergence and spread of antibiotic-resistant bacteria is a serious threat to public health. Of particular concern are Gram-negative bacteria such as Escherichia coli, Acinetobacter baumannii, Klebsiella pneumoniae or Pseudomonas aeruginosa. READ MORE

  3. 3. Human Pathogens and Antibiotic Resistant Bacteria in Polar Regions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jorge Hernández; Uppsala universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ESBL; Antibiotic Resistance; Polar Regions; Wild Birds; Mikrobiologi; Microbiology;

    Abstract : Coincident with human activity in recent decades, human-associated microorganisms have arrived to the Antarctic region, possibly linked to increasing presence of scientific bases and ship-borne tourists. In the Arctic, humans have been present for a very long time, and the few parts of the Arctic without human activities is decreasing with time. READ MORE

  4. 4. Selection of Resistance at very low Antibiotic Concentrations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Gullberg; Uppsala universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotic resistance; Selection; Antibiotic resistant bacteria; Minimal inhibitory concentration; Heavy metals; Conjugative plasmid; ESBL; Mikrobiologi; Microbiology; Biology with specialization in Microbiology; Biologi med inriktning mot mikrobiologi; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    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.

  5. 5. Relation Between Drug Exposure and Selection of Antibiotic Resistant Bacteria

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Sara K. Olofsson; Uppsala universitet.; [2006]
    Keywords : Microbiology; Pharmacokinetics; Pharmacodynamics; Antibiotic resistance; Selection; Transmission; Mathematical model; Escherichia coli; Mikrobiologi;

    Abstract : The worldwide increase in antibiotic resistance is a concern for public health. When the appropriate antibiotic dosage is determined, the priorities are efficacy and toxicity. The aim of this thesis was to gain knowledge about the most efficient dosing regimens in order to minimize the emergence and selection of antibiotic-resistant mutants. READ MORE
