1. 1. Ecological aspects of antimicrobial susceptibility of anaerobic bacteria in Nicaragua

   Författare :Mercedes Cáceres; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Antimicrobial susceptibility; normal flora; anaerobic infections; B-lactamase; enterotoxigenic B. fragilis;

   Sammanfattning : Anaerobic bacteria are the predominant constituents of the normal flora on the skin and the mucous membranes of the human body. They may also act as potent pathogens in a variety of endogenous infections. Antimicrobial resistance is an increasing problem with anaerobic and aerobic bacteria. Different mechanisms for such resistance are known. LÄS MER

3. 2. Innate and acquired immunity to commensal bacteria

   Författare :Christina Hessle; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : The innate immune system recognises molecular patterns shared by large groups of micro-organisms. Monocytes and macrophages respond to microbes by production of substances which act in concert to promote effective clearance of bacteria. LÄS MER

4. 3. Human intestinal epithelial cells in innate immunity : interactions with normal microbiota and pathogenic bacteria

   Författare :Gangwei Ou; Sten Hammarström; Marie-Louise Hammarström; Agnes Wold; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; immunologi; Immunology;

   Sammanfattning : Rod-shaped bacteria were previously shown to be associated with the small intestinal epithelium of children with celiac disease (CD). Using culture-dependent and independent methods, we characterized the microbiota of small intestine in children with CD and controls. The normal microbiota constitutes an unique organ-specific biofilm. LÄS MER

5. 4. Characterization of respiratory physiology in Lactococcus lactis for high-yield production of high-performance starter cultures

   Författare :Anna Johanson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; batch cultivations; lag phase; haemin haem; respiration-permissive conditions; aerobic growth; Lactic acid bacteria; acidification activity; continuous cultivations; starter culture production;

   Sammanfattning : Fermented food products are consumed world-wide, every day, and the demand is growing as intake increases. Lactococcus lactis is a lactic acid bacterium commonly used as a starter culture to produce fermented dairy products. LÄS MER

7. 5. Hydrogen Production by Caldicellulosiruptor species: The Organism and the Metabolism

   Författare :Ahmad Zeidan; Teknisk mikrobiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extreme thermophile; Caldicellulosiruptor; Biohydrogen; Co-culture; Coexistence; Hydrogen tolerance; Genome-scale reconstruction; In silico; Flux balance analysis;

   Sammanfattning : Hydrogen holds a great promise as an efficient and clean future energy carrier due to its high energy density and lack of pollutant generation. Anaerobic degradation of organic substrates by heterotrophic microorganisms enables the production of hydrogen from a wide spectrum of agricultural feedstock and waste products. LÄS MER
