1. 1. The faecal flora : a source of healthcare-associated infections and antibiotic resistance

   Författare :Annika Samuelsson; Håkan Hanberger; Barbro Isaksson; Jon Jonasson; Bo Söderquist; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Healthcare-associated infections (HAI) are important causes of mortality and morbidity, and antibiotic treatment is often necessary. Development and availability of new antibiotics are closely followed by development of resistance among microorganisms. During antibiotic therapy, a fraction of the antibiotic given is found in the gut. LÄS MER

3. 2. Microbiota of the alimentary tract of children - implications for allergy and inflammatory bowel disease

   Författare :Fei Sjöberg; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gut flora; child; oral flora; allergy; duodenum; inflammatory bowel disease; culture; T-RFLP; pyrosequencing;

   Sammanfattning : Allergy, which is the most common chronic disease in Swedish children and adolescents, is associated with a high standard of living and Western lifestyle. According to the hygiene hypothesis, allergy is due to inadequate stimulation of the immune system by microbes during early childhood, leading to failed maturation of the immune system. LÄS MER

4. 3. The Gut Bacterial Flora - Focus on Early Life and Physiological Traits

   Författare :Caroline Linninge; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gut microbiota; atopic eczema; inflammation; bacterial diversity; Escherichia coli; Lactobacillus plantarum; molecular-genetic methods;

   Sammanfattning : The gastrointestinal tract of the foetus is considered sterile but during vaginal birth the neonate comes into contact with bacteria from the maternal vaginal and intestinal microbiota. The main focus of this doctoral thesis was to elucidate the initial bacterial ecosystem in newborns and to relate microbial perturbations to physiological traits. LÄS MER

5. 4. β-Mannan degradation by gut bacteria - Characterization of β-mannanases from families GH5 and GH26

   Författare :Evelina Kulcinskaja; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glycoside hydrolases; gut microflora; mannan; enzymes; GH26; GH5; β-mannanase;

   Sammanfattning : The human gut flora is important for our well-being. The gut bacteria are able to degrade and metabolize complex carbohydrates. Examples of such carbohydrates are β-mannans. β-Mannans consist of a backbone of β-1,4-linked mannose units and are present in e. LÄS MER

7. 5. Early-life gut microbiota and breast milk oligosaccharides in relation to childhood immune maturation and allergy

   Författare :Ylva Margareta Sjögren; Eva Sverremark-Ekström; Outi Vaarala; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; allergy; infant; gut microbiota; human milk oligosaccharides; Bifidobacterium; Lactobacillus; Bacteroides fragilis; Clostridium difficile; family size; secretory IgA; toll like receptor; Immunology; Immunologi; immunologi; Immunology;

   Sammanfattning : Atopic allergy is the most common chronic disease among children in the developed world. This high prevalence could be associated with low microbial exposure. The early gut microbiota appears to be important for immune maturation. LÄS MER
