  1. 1. Antibiotic Resistance Selection in the Presence of Metals and Antimicrobials

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lisa M. Albrecht; Uppsala universitet.; [2018]
    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

  2. 2. Clostridium difficile : epidemiology and antibiotic resistance

    University dissertation from Örebro : Örebro universitetsbibliotek

    Author : Torbjörn Norén; Örebro universitet.; [2006]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Clostridium difficile; antibiotic resistance; epidemiology; VETERINARY MEDICINE Medicine; VETERINÄRMEDICIN Medicin; Medicin; Medicine;

    Abstract : Clostridium difficile is a spore-forming toxin-producing intestinal bacterium abundant in soils and waters. This pathogen relies on increased growth by a disturbed intestinal microflora and the production of two cytotoxins, toxin A and toxin B, which may cause anything from mild self-limiting C. READ MORE

  3. 3. Submicron Calcium Phosphate Spheres for Biomedical Applications Synthesis and Use

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tao Qin; Uppsala universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium phosphate; spheres; dentinal hypersensitivity; drug release; tooth bleaching;

    Abstract : Calcium phosphate spheres as biomaterials have been attracting attention in recent years. Calcium phosphate occurs naturally in bone, and a hollow structure could be advantageous for drug loading and release. 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. Development and Stability of Antibiotic Resistance

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Maria Sjölund; Uppsala universitet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; antibiotic resistance; selection; mutation frequency; biological cost of resistance; compensatory evolution; Helicobacter pylori; normal microbiota; Mikrobiologi; MEDICINE Microbiology; immunology; infectious diseases; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar;

    Abstract : Antibiotic resistance is of current concern. Bacteria have become increasingly resistant to commonly used antibiotics and we are facing a growing resistance problem. The present thesis was aimed at studying the impact of antibiotic treatment on pathogenic bacteria as well as on the normal human microbiota, with focus on resistance development. READ MORE
