  2. 1. Studies on bacterial transmission pathways in a high endemic area, with a focus on Helicobacter pylori

    Author : Anders Janzon; Göteborgs universitet; []
    Keywords : H. pylori; enterotoxigenic E. coli; V. cholerae; real-time PCR; transmission pathways; gastroenteritis; mouse infection models; bacterial gene expression;

    Abstract : Even though half of the world’s population is infected with Helicobacter pylori, which causes gastritis, peptic ulcer and gastric cancer, the transmission routes of these bacteria remain unknown despite extensive epidemiological studies. Enterotoxigenic Escherichia coli (ETEC) and Vibrio cholerae are two of the most common causes of acute watery diarrhea in developing countries. READ MORE

  4. 2. 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. Adaptation of Helicobacter pylori Adherence Properties in Promotion of Host Tropism and Inflammatory Disease

    Author : Marina Aspholm; Rino Rappuoli; Umeå universitet; []
    Keywords : H. pylori; BabA; SabA; adhesin; blood group antigens; sialylated; phase variation; hemagglutination; selectin; adaptation; odontologi; Odontology;

    Abstract : Being among the most prevalent of persistent infectious agents in humans worldwide, Helicobacter pylori induces chronic inflammation (gastritis), which may progress to peptic ulceration and stomach cancer. The ability to adhere to the gastric mucosa is considered to be both a colonization and virulence property of H. pylori. For adherence, H. READ MORE

  6. 4. Helicobacter pylori adhesion and patho-adaptation : the role of BabA and SabA adhesins in persistent infection and chronic inflammation

    Author : Jafar Mahdavi; Henrik Clausen; Umeå universitet; []
    Keywords : H. pylori; BabA; adhesin; Lewis b; MUC5AC; sialyl-dimeric-Lewis x; chronic inflammation; SabA; Lewis x; LPS; odontologi; Odontology;

    Abstract : Helicobacter pylori (H. pylori) is a human-specific gastric pathogen which is responsible for a spectrum of diseases ranging from superficial gastritis to gastric and duodenal ulceration, and which is also highly associated with gastric cancer. The pathogenesis of severe gastric disorders caused by H. READ MORE

  7. 5. Studies of immune responses to cell surface proteins of Helicobacter pylori and Borrelia burgdorferi by enzyme immunoassay and immunoblotting

    Author : Ingrid Nilsson; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mikrobiologi; mycology; virology; B. burgdorferi; H.pylori; cell surface proteins; gel-electrophoresis; enzyme immunoassay; Western immunoblotting; bacteriology; Microbiology; bakteriologi; virologi; mykologi;

    Abstract : Helicobacter pylori and Borrelia burgdorferi s.l. can cause chronic infections by evading the immune system. These two human pathogens express a number of immunogenic cell surface proteins. READ MORE
