  2. 1. Pollution-Induced Community Tolerance (PICT) of Bacteria: Evaluation in Phenol- and Antibiotic Polluted Soil

    Author : Louise Aldén; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antibiotics; Bacteria; Community; Fungi; Leucine incorporation; Phenols; Soil; Pollution-Induced Community Tolerance PICT ;

    Abstract : The effects of organic pollutants on the soil microbial community were studied in this work. The main aim was to evaluate the use of pollution-induced community tolerance (PICT) in studying the effects of pollution. The leucine incorporation technique (indicating bacterial growth) was used to monitor changes in tolerance. READ MORE

  4. 2. 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.

  5. 3. Chemical use in shrimp farming and environmental implications of antibiotic pollution

    Author : Sara Gräslund; Nils Kautsky; Bent Halling-Sørensen; Stockholms universitet; []
    Keywords : ;

    Abstract : Shrimp farming is a highly important industry in southeast Asia. A major threat to profitable shrimp farming is disease outbreaks, which has lead to a situation where a large number of chemicals are used to prevent and treat infections. READ MORE

  6. 4. Use of microbiomics to study human impacts on complex microbial communities

    Author : Cecilia Jernberg; Janet K. Jansson; Charlotta Edlund; Julian R. Marchesi; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The study of bacterial communities in nature is currently a challenge. The majority of bacteria in clinical and environmental samples have not yet been cultured and therefore we cannot fully understand their roles in nature and how the ecological balance in a specific microbial ecosystem can be disrupted.

  7. 5. Mechanism of Action of the Plant Growth Promoting Bacterium Paenibacillus polymyxa

    Author : Salme Timmusk; Gerhart Wagner; Janet Jansson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Plant growth promotion; Induced resistance; Biocontrol; Deleterious rhizobacterium; Mikrobiologi; Microbiology; Mikrobiologi;

    Abstract : Paenibacillus polymyxa belongs to the group of plant growth promoting rhizobacteria (PGPR). Activities associated with P. polymyxa-treatment of plants in earlier experiments include, e.g. READ MORE
