  2. 1. Lactobacillus characterization and effects on oral biofilm composition

    Author : Nelly Romani Vestman; Ingegerd Johansson; Jukka Meurman; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lactobacillus; L. gasseri; probiotic traits; oral biofilm; breastfeeding; oral microbiota; odontologi; Odontology;

    Abstract : The human body is home for millions of bacteria. The largest microbial community is located in the gastro-intestinal (GI) tract, including the oral cavity with >700 identified taxa. Lactobacillus, which is normal inhabitant of the GI tract, contributes to health by possible biofilm and immune modulation. 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. Pathogenic Neisseria infections of human neutrophils and epithelial cells : focusing on host responses and immune evasion

    Author : Niklas Söderholm; Helena Aro; Thomas Rudel; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Neisseria gonorrhoeae; Neutrophils; PMN; Epithelial cells; Polarized cells; Type IV pili; Adherence; Cell cycle; DNA damage; Lactobacillus; molekylär biovetenskap; Molecular Bioscience;

    Abstract : N. meningitidis and N. gonorrhoeae are obligate human pathogens that colonize mucosal surfaces and are often carried asymptomatically. These bacteria have developed adhesive structures that promote adherence to host cells and efficient colonization of new hosts. READ MORE

  6. 4. Bacteria-host cell interactions : Studies on initial colonization, antimicrobial peptides, and biofilms

    Author : Gabriela Wassing; Ann-Beth Jonsson; Elena Vikström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Lactobacillus; host responses; EGR1; antimicrobial peptides; hBD2; A20; biofilm; molekylär biovetenskap; Molecular Bioscience;

    Abstract : The obligate human pathogen Neisseria meningitidis asymptomatically colonizes the upper respiratory tract, but crossing of the epithelial barrier can cause life-threatening meningitis and/or sepsis. N. READ MORE

  7. 5. Neisseria gonorrhoeae and Lactobacillus from initial adherence to effects on human cells

    Author : Katarina Vielfort; Helena Aro; Bernt Eric Uhlin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neisseria gonorrhoeae; Lactobacillus; adhesion; cell cycle; DNA damage; Neutrophils; molekylärgenetik; Molecular Genetics;

    Abstract : The causative agent of gonorrhoea Neisseria gonorrhoeae (gonococcus) colonises the urogenital tract epithelia. The vaginal tract microbiota of healthy females is dominated by Lactobacillus species. In paper I, the ability of lactobacilli to protect cervical cells against gonococcal adherence was investigated.
