  1. 21. Tularemia : epidemiological, clinical and diagnostic aspects

    Författare :Henrik Eliasson; Erik Bäck; Anders Sjöstedt; Clas Ahlm; Örebro universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Francisella; tularemia; epidemiology; case-control; diagnosis; PCR; clinical characteristics; immunology; ELISA; lymphocyte stimulation; Medicine; Medicin; Infektionssjukdomar; Infectious Diseases;

    Sammanfattning : Tularemia is a zoonosis caused by the small, fastidious, gram-negative rod Francisella tularensis that appears over almost the entire Northern Hemisphere. In Sweden, tularemia has appeared mainly in restricted areas in northern parts of central Sweden. LÄS MER

  3. 22. Environmental factors selecting for predation resistant and potentially pathogenic bacteria in aquatic environments

    Författare :Peter Mathisen; Agneta Andersson; Johanna Thelaus; Mats Forsman; Anders Sjöstedt; Tron Frede Thingstad; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Eutrophication; productivity; predation pressure; predation-resistant bacteria; pathogens; Francisella tularensis; adaptation; biomarker; oligotyping;

    Sammanfattning : The long history of co-existence of bacteria and their protozoan predators in aquatic environments has led to evolution of protozoa resistant bacteria (PRB). Many of these bacteria are also pathogenic to humans. LÄS MER

  4. 23. Towards the Limits – Climate Change Aspects of Life and Health in Northern Sweden : studies of tularemia and regional experiences of changes in the environment

    Författare :Maria Furberg; Maria Nilsson; Anders Johansson; Lars Weinehall; Peter Friberg; Umeå universitet; []
    Nyckelord :Climate change; public health; Indigenous peoples; Sami; reindeer herding; resilience; tularemia; mixed-methods; infectious disease; seroprevalence; ELISA; outbreak investigation; risk factor; ecology; Francisella tularensis; Epidemiology; epidemiologi; folkhälsa; Public health;

    Sammanfattning : BackgroundIndigenous peoples with traditional lifestyles worldwide are considered particularly vulnerable to climate change effects. Large climate change impacts on the spread of infectious vector-borne diseases are expected as a health outcome. LÄS MER

  5. 24. Cycles of voles, predators, and alternative prey in boreal Sweden

    Författare :Birger Hörnfeldt; S. Erlinge; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3-4 year cycles; Clethrionomys glareolus; Clethrionomys rufocanus; Microtus agrestis; snap-trapping; rate of change; population regulation; delayed density-dependence; time-lag mechanism; seasonality; predation; food; predator avoidance; foraging behaviour; Aegolius funereus; nest boxes; numerical response; nomadism; Vulpes vulpes; Sarcoptes scabiei vulpes; Lepus timidus; Francisella tularensis; Tetraonidae; hunting statistics; zooekologi; Animal Ecology;

    Sammanfattning : Bank voles, grey-sided voles, and field voles had synchronous 3-4 year density cycles with variable amplitudes which averaged about 200-fold in each species. Cycles of vole predators (red fox and Tengmalm's owl), and their (foxes') alternative prey (mountain hare and forest grouse) lagged behind the vole cycles. LÄS MER

  7. 25. Interaction between waterborne pathogenic bacteria and Acanthamoeba catellanii

    Författare :Hadi Abd; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Francisella tularensis; Pseudomonas aeruginosa; Vibrio cholerae; Acanthamoeba castellanii; predation; intracellular behaviour; symbiosis; environmental reservoir;

    Sammanfattning : Waterborne bacteria cause global public health problems. Francisella tularensis causes tularemia, which is a fatal disease in humans. Pseudomonas aeruginosa is an opportunistic and nosocomial pathogen of humans. Vibrio cholerae O1 and V. LÄS MER
