    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

  5. 13. Genome-plasticity and adaption in Helicobacter pylori

    Author : Christina Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Helicobacter pylori is a gastric bacterial pathogen that infects an estimated half. of the human population. The infection is primarily acquired during early childhood and causes a persistent infection that is usually not eradicated by the host immune system. Although most infected individuals. READ MORE

    Abstract : Background: Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system (CNS). Its etiology is unknown and there exists no cure. READ MORE

  7. 15. Genetic adaptations of Helicobacter pylori during gastric disease progression

    Author : Helene Kling Bäckhed; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Helicobacter pylori colonizes the stomachs of approximately half of all humans. In the absence of treatment, H. pylori can persist throughout the life of the host. Although most infected individuals are asymptomatic, a significant proportion develops peptic ulcer disease, chronic atrophic gastritis (ChAG) or gastric adenocarcinoma. READ MORE
