  1. 1. Microbial risk assessment and its implications for risk management in urban water systems

    Author : Therese Westrell; Thor-Axel Stenström; Nick Ashbolt; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Quantitative microbial risk assessment; pathogens; urban; decentralised; failures; noroviruses; water consumption; HACCP; drinking water; wastewater; sludge; faeces; risk management; Water in nature and society; Vatten i natur och samhälle;

    Abstract : Infectious disease can be transmitted via various environmental pathways, many of which are incorporated into our water and wastewater systems. Quantitative microbial risk assessment (QMRA) can be a valuable tool in identifying hazard exposure pathways and estimating their associated health impacts. READ MORE

  2. 2. Optimisation of diagnostic PCR a study of PCR inhibitors in blood and sample pretreatment

    Author : Waleed Abu Al-Soud; Avdelningen för medicinsk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mycology; virology; bacteriology; Microbiology; AmpliTaq Gold; Amplification facilitators; Betaine; Blood culture medium; Blood; BSA; cheese; faeces; gp32; Haemoglobin; Ions; Immunoglobulin G; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : PCR is widely employed as a rapid, sensitive and specific molecular diagnostic technique in clinical diagnosis, environmental investigations and for monitoring biotechnical processes. However, the full potential of diagnostic PCR is limited, in part, by the presence of PCR-inhibitory substances in biological samples. READ MORE

  3. 3. PCR-based detection of microorganisms in complex biological samples

    Author : Pär-G Lantz; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Density gradient centrifugation; DNA extraction; Aqueous two-phase systems; Meat; Faeces; Cheese; Yeast; Helicobacter pylori; Yersinia enterocolitica; Listeria monocytogenes; PCR; Inhibition; Sample preparation; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The detection of microorganisms by PCR can be divided into four steps: (1) sample collection, (2) sample preparation, (3) DNA amplification and (4) detection of PCR products. The major problem in developing PCR-based detection methods is the sample preparation step. READ MORE

  4. 4. Lactobacillus reuteri in health and disease

    Author : Gabriela Sinkiewicz; Malmö högskola; []
    Keywords : breast milk; lactobacilli; Lactobacillus reuteri; probiotics; Bifidobacteria; clostridium; faeces; Gingivitis; oral health;

    Abstract : People have exploited fermentation by lactobacilli for centuries as a means of preparing and preserving foods. Several different bacterial species are today used as probiotic bacteria in different products both for human and animal applications. READ MORE

  5. 5. Treatment technologies for human faeces and urine

    Author : Charles Niwagaba; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Abstract : This thesis examines simple, cheap, environmentally friendly and resource efficient technologies for the treatment of source-separated human faeces and urine to enable safe recycling of their plant nutrients for plant production in developing countries. Composting of faeces-to-food waste (F:FW) in wet weight mix ratios of 1:0, 3:1 and 1:1 was studied in 78 L reactors insulated by 25 mm styrofoam; and of F:FW in wet volume/weight ratios of 1:0, 1:1 and 1:3 in 216 L reactors insulated by 75 mm styrofoam.
