  2. 1. Development and dynamics of the normal gut microbiota

    Author : Lisa M. Olsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dynamics; ecology; gut microbiome; gut microbiota development; microbiota; richness; Prader-Willi Syndrome; stability; variation;

    Abstract : Altered gut microbiota configurations have been linked to human diseases. To identify mechanistic links between altered gut microbiota and disease states, definitions of the healthy gut microbiota need to be established. READ MORE

  4. 2. Lactobacilli in the normal microbiota and probiotic effects of Lactobacillus plantarum

    Author : Elisabeth Lönnermark; Göteborgs universitet; []
    Keywords : lactobacillus; oral microbiota; gut microbiota; infants; adults; secretory IgA; IgA-deficiency; adherence; Lactobacillus plantarum; probiotics; antibiotics; salmonellosis; diarrhoea;

    Abstract : Lactobacilli colonise most adult individuals and are also frequently used as probiotics, i.e. bacteria which possibly have health promoting effects when ingested. In this thesis, the intestinal Lactobacillus microbiota was studied in longitudinally followed infants. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Development and Stability of Antibiotic Resistance

    Author : Maria Sjölund; Lars Engstrand; Dan Andersson; Pentti Huovinen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; antibiotic resistance; selection; mutation frequency; biological cost of resistance; compensatory evolution; Helicobacter pylori; normal microbiota; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar;

    Abstract : Antibiotic resistance is of current concern. Bacteria have become increasingly resistant to commonly used antibiotics and we are facing a growing resistance problem. The present thesis was aimed at studying the impact of antibiotic treatment on pathogenic bacteria as well as on the normal human microbiota, with focus on resistance development. READ MORE

  7. 5. Infections Related to the Use of Medical Devices and Changes in the Oropharyngeal Flora

    Author : Hulda Thorarinsdottir; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thrombosis; critical illness; biofilm; intratracheal intubation; ventilator-associated pneumonia; ; central venous catheters; catheter-related infections; proton pump inhibitors; oropharynx; MICROBIOTA; foreign-body reaction; hemolysis; inflammation;

    Abstract : Background: Humans exist in mutualistic balance with a large range of microbiota. Illness and hospitalization can disturb this balance and contribute to hospital-acquired infections (HAIs), which occur most often in critically ill patients. READ MORE
