  1. 1. Pathogen inactivation and quantitative microbial risk assessment for Peepoo sanitation system, Kibera

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Linnea Eriksson; Lisa Sundberg; [2020]
    Nyckelord :Quantitative microbial risk assessment; ammonia sanitisation; faeces; risk assessment; inactivation model; pathogen; Ascaris; E. coli; Campylobacter; Enterococcus; sanitation system; sanitisation technology;

    Sammanfattning : Unsafe sanitation systems poses a risk for pathogen transmission, wherefore it is important to both inactivate pathogens present in human excreta and conduct safe sanitation systems from use to end-use. The Peepoo toilet, using ammonia sanitisation, have been suggested as a low-cost sanitation solution and is implemented in schools in Kibera, an urban slum in Kenya. LÄS MER

  3. 2. Development of a bacterial infection model in zebrafish embryos with special focus on colistin-resistant Klebsiella pneumoniae

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Anna Tamara Leber; [2019]
    Nyckelord :Danio rerio; embryo model; microinjection; innate immunity; inflammation; Klebsiella pneumoniae; colistin-resistance; antimicrobial peptides; cross-resistance;

    Sammanfattning : Zebrafish (Danio rerio) is a promising model organism for immunological studies. A time window between the development of the innate and adaptive immune system makes it possible to investigate the mechanisms originating exclusively from the innate immune system. LÄS MER

  4. 3. Inactivation of viruses in water by chlorination using bacteriophages as model organisms

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

    Författare :Charan Raju Kanna; [2016]
    Nyckelord :desinfection; chlorination; bacteriophages; viruses; free chlorine;

    Sammanfattning : Climate change will lead to more extreme rain events in parts of Sweden resulting in sewage overflows and thus more contamination of surface water, leading to an increased risk of waterborne infections. Swedish and Norwegian surface waters are rich in humic substances with high organic carbon content that interferes with disinfection, the most important barrier to viruses in the water treatment plant.

  5. 4. Potential to inactivate microorganisms in sewage sludge by ammonia treatment : different temperatures and urea additions

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Fredrik Wirell; [2015]
    Nyckelord :Ammonia; Urea; Sewage sludge; inactivation; reduction; Thermo tolerant coliform bacteria; Salmonella; E. coli; Enterococci; Somatic coliphage;

    Sammanfattning : Sewage sludge is rich in nutrients and organic matter, both of which can be useful in the agricultural system. By recycling the nutrients from our excreta, a more sustainable use of nutrients in agriculture can be achieved and the use of mineral fertilizer can thereby be decreased. LÄS MER

  7. 5. Virus removal during artificial groundwater recharge and the effects of organic matter : Tunåsen infiltration basins, Uppsala, Sweden

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Lisanne Hölting; [2015]
    Nyckelord :drinking water; artificial groundwater recharge; bacteriophages; organic matter; adsorption;

    Sammanfattning : Die Verunreinigung von Trinkwasser mit pathogenen Mikroorganismen kann zu epidemischen Krankheitsausbrüchen führen und stellt daher weltweit ein Risiko für die menschliche Gesundheit dar. Oberflächengewässer sind im Gegensatz zu Grundwasser anfälliger für Verunreinigungen. LÄS MER
