  1. 1. Untangling ambiguities in the microbial fossil record : experimental abiotic and biological approaches

    Författare :Sigrid Huld; Anna Neubeck; Sebastian Willman; Sean McMahon; Barbara Cavalazzi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chemical gardens; pseudofossils; experimental mineralisation; microbial fossils; methanogens;

    Sammanfattning : Life on early earth has long been the topic of discussion for many researchers: how did it come to be? Which cells came first? Where can we find them? The most ancient rocks on our planet may hold some of the answers to these questions, but many may only be answered in laboratories. Chemical and morphological traces can be found from Archaean deposits, tantalisingly similar to modern day prokaryotes. LÄS MER

  3. 2. Microbial Risks in Surface Water Sources

    Författare :Johan Åström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Surface water; Bifidobacteria; Microbial source tracking; Cryptosporidium.; QMRA; Flow-weighted sampling; Pathogens; Bacteroidales; Stochastic modelling; qPCR;

    Sammanfattning : Microbial risks need to be properly handled for the provision of healthy drinking water. The mitigation of pathogens in the water source lowers the risk for infection associated with nominal and suboptimal drinking water treatment. LÄS MER

  4. 3. Characterisation of the Microbial Community in Indoor Environments: a Chemical-Analytical Approach

    Författare :Aleksandra Sebastian; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air; microbial chemical markers; asthma; allergies; tobacco smoke; Infektioner; Infections;

    Sammanfattning : Inhalation of airborne microorganisms and their toxic components and products may induce a wide spectrum of acute and chronic airway manifestations. The study describes important capabilities of chemical marker analysis in defining human exposure to microorganisms in indoor environments. LÄS MER

  5. 4. Microorganisms in indoor environments. A search for health-related measurements

    Författare :Loay Wady; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; bacteriology; virology; Microbiology; schools; microbial markers; MVOCs; building materials; dust; GC MSMS; SPME;

    Sammanfattning : Microorganisms are ubiquitous in indoor air and epidemiological data suggest that inhalation of microbes and/or their products adhered on air–borne dust particles can impair well–being and health. In the present thesis microbial volatile organic compounds (MVOCs) and cellular markers were studied by gas chromatography–mass spectrometry (GC/MS). LÄS MER

  7. 5. Cervical and intra-amniotic markers of preterm birth and infection

    Författare :Rose-Marie Holst; Göteborgs universitet; []
    Nyckelord :spontaneous preterm delivery; intra-amnioti infection inflammation; preterm labor; inflammatory proteins; preterm prelabor rupture of membranes; histological chorioamnionitis; cervical and amniotic markers;

    Sammanfattning : Abstract Background: Preterm delivery (PTD; < 37 gestational weeks), is one of the greatest unsolved obstetrical problems worldwide. As much as 80% of the perinatal mortality and 50% of the long-term neurological handicaps are associated with PTD. Spontaneous preterm birth (SPTD), i.e. LÄS MER
