    Sammanfattning : Rhizobium leguminosarum biovar trifolii (Rlt) is a root-associated soil bacterium (rhizobia) capable of entering a symbiotic relationship with various species of clover (Trifolium sp.) and fix nitrogen within root nodules. LÄS MER

  3. 2. Beaver wetland and lake effects on Francisella tularensis in Swedish landscapes and hares

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Lovisa Pihlgren Hökby; [2022]
    Nyckelord :tularemia; francisella tularensis hola; beavers; hares; wetland restauration; epizoology; vector borne diseases;

    Sammanfattning : The zoonotic disease tularemia is caused by the bacterium Francisella tularensis that infects both humans and wildlife in Sweden. Associations between outbreaks of tularemia and lakes and rivers have earlier been observed, and semi-aquatic rodents and mosquitoes are believed to be key species groups in the epidemiological cycle of the disease.

  4. 3. The metagenomes of root nodules in actinorhizal plants : A bioinformatic study of endophytic bacterial communities

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Ellen Fasth; [2021]
    Nyckelord :Actinorhizal plants; Frankia; endosymbiosis; root nodules; metagenomes; bioinformatics;

    Sammanfattning : Actinorhizal plants are in symbiosis with the nitrogen-fixating soil bacterium Frankia, which forms nodules in the plant root. However, several studies also report other endophytic bacteria appearing in the nodules, but their function and interaction with the host plant or Frankia is not yet understood. LÄS MER

  5. 4. Multi-drug resistant Gram-negative bacteria in wastewater treatment plants : -With focus on Acinetobacter baumannii complex

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Joanna Eaton; [2020]
    Nyckelord :;

    Sammanfattning : Multidrug-resistant (MDR) pathogens are emerging problems humanity faces today. Increasing MDR Gram-negative bacteria is not only a threat towards humanity itself but also towards food safety. The genus Acinetobacter is an environmental bacterium that can be found in habitats, including aquatic environments, soil, wastewater, food, and animals. LÄS MER

  7. 5. Levande begravd : kan klimatförändringar ge mjältbrandssporer nya förutsättningar?

    Kandidat-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Johanna Cavell; [2019]
    Nyckelord :mjältbrand; sporer; klimatförändringar;

    Sammanfattning : Mjältbrand är en dödlig sjukdom som varit känd under en lång tid och som drabbar både djur och människor. En av anledningarna till att mjältbrand är fruktad är bakteriens förmåga att sporulera vid icke gynnsamma förhållanden och persistera i jorden under en lång tid. LÄS MER
