  2. 6. 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

  4. 7. New antibiotic resistance genes and their diversity

    Author : Fanny Berglund; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metagenomics; β-lactamases; hidden Markov model; antibiotic resistance; carbapenemases; big data; tetracycline resistance;

    Abstract : Antibiotic resistance is increasing worldwide and is considered a severe threat to public health. Often, antibiotic resistance is caused by antibiotic resistance genes, of which many are hypothesized to have been transferred into human pathogens from environmental bacteria. READ MORE

  5. 8. Selection of Resistance at very low Antibiotic Concentrations

    Author : Erik Gullberg; Dan I Andersson; Diarmaid Hughes; Linus Sandegren; Laura Piddock; Uppsala universitet; []
    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.

  6. 9. Development and Stability of Antibiotic Resistance

    Author : Maria Sjölund; Lars Engstrand; Dan Andersson; Pentti Huovinen; Uppsala universitet; []
    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; Microbiology; immunology; infectious diseases; 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

  7. 10. On the Origins of mobile Antibiotic Resistance Genes : A comparative genomics approach

    Author : Stefan Ebmeyer; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antibiotic resistance; comparative genomics; bacterial genomics; antibiotic resistance genes;

    Abstract : Mobile antibiotic resistance genes (ARGs), transferable between bacterial cells, are major contributors to the antibiotic resistance crisis we are facing today. From which organisms pathogens acquired these genes is mostly unknown, yet knowledge about their origin is needed in order to limit the emergence and spread of novel ARGs in the future. READ MORE
