  2. 1. Helicobacter pylori : molecular mechanisms for variable adherence properties

    Author : Anna Vallström; Anna Arnqvist; Kristian Riesbeck; Umeå universitet; []
    Keywords : H. pylori; adherence; BabA; SabA; Leb; sLex; phase variation; recombination; vesicles;

    Abstract : More than half of all people worldwide are infected with H. pylori. The infection always cause a gastric inflammation that may develop into peptic ulcer disease or gastric cancer. Attachment proteins, adhesins, mediate specific adherence of H. READ MORE

  5. 3. Escherichia coli Fimbriae, Bacterial Persistence and Host Response Induction in the Human Urinary Tract

    Author : Göran Bergsten; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; IL-8; IL-6; neutrophils; GFP; mucosal host response; Type 1 fimbriae; P fimbriae; adherence; virulence factors; regulation; deliberate colonisation; Escherichia coli 83972; Urinary tract infection; asymptomatic bacteriuria;

    Abstract : Urinary tract infections (UTI) are among the most common bacterial infections in humans. Symptomatic UTIs may be acute, recurrent or chronic but the most frequent form of UTI is asymptomatic bacteruria (ABU). In ABU, the mucosa remains inert, despite the presence of large bacterial numbers in urine. READ MORE

  6. 4. 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

  7. 5. Interplay between bacteria and host epithelial cells

    Author : Lisa Maudsdotter; Ann-Beth Jonsson; Cindy Grove Arvidson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbial-cell interaction; Adherence; Infection; Lactic acid bacteria; Antimicrobial peptides; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Bacterial pathogens have developed multiple ways of manipulating host cell functions to exploit the host environment. We found that interactions with epithelial cells increase the resistance of the human pathogen Neisseria meningitidis to the antimicrobial peptide LL-37. READ MORE
