  1. 6. Impact of Bifidobacterium longum and Lactobacillus acidophilus on the intestinal microflora and bioavailability of some food mutagens

    Författare :Kerstin Orrhage; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The gastrointestinal microflora is a complex ecological system, normally characterised by a flexible equilibrium. The most important role of the microflora, from the point of view of the host, is probably to act in colonisation resistance against exogenous, potentially pathogenic, microorganisms. LÄS MER

  3. 7. Ecological impact of antibiotic treatment on human normal microflora

    Författare :Mamun-Ur Rashid; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Ceftobiprole;

    Sammanfattning : The skin and the mucosal surfaces of humans are colonized with microorganisms which are often referred as the normal microflora. There is a biological balance between the human host and the normal microflora in health. The extensive use of antibiotics in both humans and animals has caused the development of many resistant bacteria. LÄS MER

  4. 8. An exploratory journey into probiotic interactions : Bioactive properties of Limosilactobacillus reuteri and Bifidobacterium longum

    Författare :Ludwig Lundberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Probiotics are defined as live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. The mechanisms by which probiotics affect the host are based on one of two principles: i) directly, by interacting with specific targets, or ii) indirectly, by contributing to the ecological niche constructions of the microbiota.

  5. 9. Feeding Lactobacillus paracasei ssp. paracasei strain F19 to infants during weaning : effects on adaptive immunity and gut microbial function

    Författare :Christina West; Olle Hernell; Marie-Louise Hammarström; Outi Vaarala; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adaptive immunity; allergy; complementary food; eczema; gut microbiota; infections; probiotics; short-chain fatty acids; Th1 Th2; weaning; Paediatric medicine; Pediatrisk medicin;

    Sammanfattning : Introduction: Gut microbial composition has been associated with immune-mediated diseases. Breastfeeding yields a microbiota rich in bifidobacteria and promotes colonization by lactobacilli. Bifidobacteria and lactobacilli are considered health-promoting and are used as probiotics, i.e. LÄS MER

  7. 10. Bacterial colonization of the neonatal bowel and ileal pouch with focus on E. coli

    Författare :Anna Östblom; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; E. coli; persistens; intestinal microbiota; colonization; ileal pouch; persistence; virulence factor genes;

    Sammanfattning : The colonic microbiota is a source of inflammatogenic and potentially pathogenic bacteria, but also a source of immune maturation signals to the infant. Here, we have investigated the normal colonic microbiota, with focus on E. coli in Swedish and Pakistani newborn infants, as well as the microbiota of the ileo-anal pouch in colectomized patients.
