1. 1. Staphylococcus aureus in the infantile bowel flora

   Författare :Erika Lindberg; Göteborgs universitet; []
   Nyckelord :Staphylococcus aureus; intestinal; microflora; superantigen; RAPD; bacteria; infants;

   Sammanfattning : The increasingly hygienic life-style in Western societies may not only have reduced infections, but may also have altered the composition of the commensal microflora, which may, in turn, have predisposed to e.g. allergy development. Here we investigated the first year s intestinal colonization pattern of a Swedish birth-cohort. LÄS MER

3. 2. Gut microflora associated characteristics in children with celiac disease

   Författare :Bo Tjellström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Celiac disease; children; faeces; microflora associated characteristics; short chain fatty acids; branched-chain fatty acids; iso-butyric acid; iso-valeric acid; relatives; faecal microflora; faecal tryptic activity; screening;

   Sammanfattning : Aim: The over-arching aim of this thesis was to study some metabolic functions of the gut microflora in children with known or screening detected celiac disease (CD) and their first-degree relatives. Materials: Study I. A number of 36 untreated CD children, 47 after at least 3 months on glutenfree diet (GFD) and 42 healthy controls (HC). Study II. LÄS MER

4. 3. Faecal short-chain fatty acids as an indicator of the status of intestinal microbial ecology

   Författare :Urmas Siigur; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Intestinal microflora; SCFAs; Faecal water; Breast-feeding; Metronidazole; Lactose malabsorption; Bacterial diarrhoea; Olestra;

   Sammanfattning : The aims of this study were to investigate how faecal concentrations of short chain fatty acids (SCFAs) reflect intestinal microbial ecology. Faecal SCFAs and water content were determined in 93 healthy volunteers to establish the normal values in man and the correlations between various SCFAs and between SCFAs and faecal water. LÄS MER

5. 4. Development of allergy, salivary IgA antibodies and gut microbiota in a Swedish birth cohort

   Författare :Anna Sandin; Agnes Wold; Umeå universitet; []
   Nyckelord :pet keeping; sensitisation; intestinal microflora; short chain fatty acids; allergy; salivary IgA; late-onset wheezing; pediatrik; Pediatrics;

   Sammanfattning : The increasing prevalence of allergic diseases in affluent societies has been associated with changes in microbial exposure early in life and a less diverse gut flora. The objective of this thesis was to assess the development of allergic sensitisation and symptoms during the first four years of life in a non-selected birth cohort in relation to environmental factors, family history, gut microbiota and salivary IgA antibodies.

7. 5. Ecological disturbances and emergence of resistance in the oral and gastrointestinal microflora after drug exposure

   Författare :Christina Stark; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :ecology antimicrobial resistance oral gastrointestinal microflora B-lactamase enzyme induction.;

   Sammanfattning : The exposure of antimicrobial agents and antacids may disturb the ecological balance of the normal microflora. This influence often leads to decreased colonization resistance due to repression of sensitive bacteria and selection of resistant bacteria which have acquired resistance during therapy. LÄS MER
