  1. 1. Development of a simplified and cost effective norovirus capsid typing method using next generation sequencing

    Magister-uppsats,

    Författare :Ronnie Eriksson; [2023]
    Nyckelord :PCR; Foodborne virus; Food safety; Illumina; NGS;

    Sammanfattning : Human noroviruses are a major cause of acute gastroenteritis worldwide and can betransmitted through consumption of contaminated raw food. Shellfish like oysters can becontaminated by human sewage during production and accumulate multiple Norovirus strainsin low concentrations. LÄS MER

  3. 2. Hydraulic Modeling and Quantitative Microbial Risk Assessment of Intrusionin Water Distribution Networks Under Sustained Low-Pressure Situations

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Maryam Shakibi; [2022]
    Nyckelord :drinking water distribution network; EPANET; hydraulic modelling; low pressure; pathogen intrusion; Quantitative Microbial Risk Assessment QMRA ; distributionsnät för dricksvatten; EPANET; hydraulisk modellering; lågtryck; patogen inläckage; Kvantitativ mikrobiell riskbedömning QMRA ;

    Sammanfattning : Drinking water systems aim to remove, reduce, and prevent microbial contamination in water by usingmultiple barriers from catchments to consumers. Water distribution networks are vulnerable tocontamination from external sources if they lose their physical or hydraulic integrity. LÄS MER

  4. 3. A Quantitative Microbial Risk Assessment Associated with Cross-Connections in the Drinking Water Network in Combination with Hydraulic Modeling

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Fatin Alzuhairi; [2022]
    Nyckelord :EPANET; QMRA; Water distribution network; Health risk analysis; Cross-connections and backflow; Low pressure; Water quality; Simulation; Pathogen; EPANET; QMRA; vattendistributionsnät; hälsoriskanalys; korskoppling; lågtryck; vattenkvalitet; simulering; patogen;

    Sammanfattning : Drinking water companies have the technology and responsibility to deliver safe and high-quality drinking water to the water distribution systems network (WDN). However, many events within the WDN, such as cross-connections and backflow, might degrade water quality and pose public health risks to consumers. LÄS MER

  5. 4. Evaluation and performance comparison between two commercial multiplex gastroenteritis diagnostic systems in a routine laboratory setting

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

    Författare :Nasim Estelle Rabe; [2021]
    Nyckelord :BD MAXTM System; BioFire® FilmArray® Torch System; Adenovirus F40 41; Human Astrovirus; Norovirus GI GII; Rotavirus; Sapovirus.;

    Sammanfattning : Abstract Background: Gastroenteritis is a common infection and the leading cause of morbidity worldwide and is mostly caused by viruses. Outbreaks appear in both developed and developing countries and result in large economic costs. Rapid detection is important for appropriate treatment, control and to prevent the spread of infection.

  7. 5. Tidsserieanalys av aktiv norovirus-infektion med RT-qPCR

    Kandidat-uppsats, Högskolan Kristianstad/Fakulteten för naturvetenskap

    Författare :Henrik Dahlin; [2019]
    Nyckelord :RT-qPCR; SYBR Green; Norovirus; MNV; One-Step Growth Analysis; Winter vomiting disease; RT-qPCR; SYBR Green; Norovirus; MNV; One-Step Growth Analysis; Vinterkräksjukan;

    Sammanfattning : Norovirus som orsakar vinterkräksjukan är en av de vanligaste vintersjukdomarna i Sverige. Sjukdomstiden varar generellt i en till tre dagar med symptomen kräkning och/eller diarré. Till den totala sjukdomsbilden världen över gällande akut gastroenterit, bidrar norovirus med 18 %. LÄS MER
