  2. 21. Human salmonellosis : impact of travel and trade from a Swedish perspective

    Author : Birgitta De Jong Skierus; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Salmonella; salmonellosis; reptile-associated salmonellosis; travel-associated salmonellosis; S. Enteritidis; European salmonella incidence; serotype; serovar; sewage treatment plants; antibiotic resistant; pre-travel advice.;

    Abstract : Background: Salmonellosis is one of the most important gastrointestinal infections in humans. The vast majority of Swedish Salmonella cases have acquired the disease abroad, reflecting both a large number of Swedish travellers and a very favourable domestic Salmonella situation compared to other countries, mainly due to various control programs implemented in the animal food production and import regulations (e.

  4. 22. Population structure and antibiotic resistance of the genus enterococcus in humans, animals and the environment

    Author : Aina Iversen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Enterococci; epidemiology; ecology; food animals; humans; environment; vancomycin resistance; sewage; transmission; diversity; antibiotic resistance; surveillance;

    Abstract : Enterococci belong to the normal intestinal flora of humans and animals. An increased prevalence of antibiotic resistant enterococci causing nosocomial infections has drawn attention to the epidemiology and emergence of antibiotic resistance in this genus. READ MORE

  5. 23. Endocrine disrupting compounds in effluent waters : Chemical analysis to evaluate exposure of fish

    Author : Maria Pettersson; Lillemor Asplund; Leif Kronberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Abstract : The aim of this thesis was to investigate if endocrine disruption related to the release of estrogenic and/or androgenic substances via sewage treatment plant and pulp mill effluents is significant in Swedish waters. Chemical analysis of bile fluid in combination with measurement of biomarkers was used for the evaluation of internal exposure and effects in fish. READ MORE

    Abstract : Production of biogas through anaerobic digestion is one pathway to achieving the European Union (EU) goals of reducing greenhouse gas emissions, increasing the share of renewable energy, and improving energy efficiency. In this thesis, two different models (Anaerobic Digestion Model No. READ MORE

  7. 25. From Proteomic Analysis to Biomarker Application - Studies of Carbonyl Reductase in Fish

    Author : Eva Albertsson; Göteborgs universitet; []
    Keywords : Fish; Proteomics; Biomarker; Carbonyl Reductase; AhR agonists; Oxidative stress; Biomonitoring;

    Abstract : Many anthropogenic substances are present in the aquatic environment, but there is limited information on how this combination of chemicals affects exposed wildlife. To assess the impact of chemicals, a biomarker approach is frequently applied in environmental biomonitoring programmes. READ MORE
