  2. 6. Perspectives on urban wastewater as a source of microbial pollution

    Author : Stina-Mina Ehn Börjesson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wastewater; Mallards; Anas platyrhynchos; E. faecium; E. faecalis; Campylobacter jejuni; Vibrio parahaemolyticus;

    Abstract : Wastewater treatment plants are important links for dissemination of intestinal bacteria into surface waters. In this study, twelve mallards were exposed to treated wastewater for a period of 55 days. Faecal samples were collected and analysed for Enterococcus spp. and C. READ MORE

  4. 7. Biofilms and microbial barriers in drinking water treatment and distribution

    Author : Jonas Långmark; Gunnar Jacks; Jean Claude Block; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Mikrobiologi; Microbiology; Mikrobiologi;

    Abstract : The primary objective of conventional drinking water treatment and distribution is to deliver to the consumer water that is both aesthetically pleasing and does not constitute a human health risk. To achieve this, water utilities employ a range of physical (i.e. sand and membrane filtration) and chemical (i. READ MORE

  5. 8. 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.

  6. 9. Persistent infection by Yersinia pseudotuberculosis

    Author : Kemal Avican; Maria Fällman; Wyndham W. Lathem; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Persistent infection; RNA-seq; PMNs; Yersinia; Transcriptome; wrba; fnr; rovA; arcA; rfaH; molekylärbiologi; Molecular Biology; Infectious Diseases; infektionssjukdomar; immunologi; Immunology;

    Abstract : Enteropathogenic Yersinia species can infect many mammalian organs such as the small intestine, cecum, Peyer’s patches, liver, spleen, and lung and cause diseases that resemble a typhoid-like syndrome, as seen for other enteropathogens. We found that sublethal infection doses of Y. READ MORE

  7. 10. Sediment remediation using activated carbon: amending knowledge gaps

    Author : Robert A. Rämö; Jonas S. Gunnarsson; Agnes M. L. Karlson; Francisco J. A. Nascimento; Barbara Beckingham; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sediment contamination; sediment remediation; sorbent amendment; activated carbon; benthic community; macroinvertebrates; Baltic Sea; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : Many coastal sediments have accumulated large quantities of contaminants from past anthropogenic activities and now act as a secondary emission source of legacy pollutants to coastal ecosystems. New sediment remediation strategies are needed to address widespread sediment pollution. READ MORE
