  2. 1. The Francisella pathogenicity island : its role in type VI secretion and intracellular infection

    Author : Lena Meyer; Anders Sjöstedt; Siobhan C. Cowley; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Francisella; FPI; Type VI Secretion; Igl; DotU; VgrG; Pdp; microinjection; phagosomal escape; intracellular replication; Clinical Bacteriology; klinisk bakteriologi;

    Abstract : Intracellular bacteria have developed various mechanisms to enter and persist in host cells and, at the same time, to evade the host immune response. One such pathogen is Francisella tularensis, the etiological agent of tularemia. READ MORE

  4. 2. Occurrence and pathogenicity of tree-pathogenic fungi vectored by bark beetles

    Author : Kateryna Davydenko; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Fungal pathogens associated with bark beetles represent one of the most significant problems to forest health. Among these fungi, ophiostomatoid group are known to be most commonly associated with bark beetles. READ MORE

  5. 3. Diversity and persistence of Helicobacter pylori

    Author : Annelie Lundin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Helicobacter pylori; genomic diversity; cag pathogenicity island; Nudix hydrolase;

    Abstract : Helicobacter pylori is an exceptionally diverse bacterial species, and every infected individual harbors a unique strain, apart from the strain concordance found in some families. The infection is usually acquired during childhood and once established, persists for life unless treated with antibiotics. READ MORE

    Author : Mårten Kivi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Helicobacter pylori; epidemiology; transmission; family; two-stage; missing data; molecular typing; CagA; cag pathogenicity island; variability; microarray;

    Abstract : The bacterium Helicobacter pylori infects the gastric mucosa of about half of the world's population. The infection causes gastritis and contributes to the development of peptic ulcer disease and gastric cancer. H. READ MORE

  7. 5. On extrinsic and intrinsic organizational themes in gram negative bacteria and their role in evolution and virulence of the bacterial genus Salmonella spp

    Author : Anders Folkesson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Salmonella; fimbriae; evolution; cell wall; peptidoglycan;

    Abstract : Gram-negative bacteria are composed of intrinsic organizational themes such as outer and inner membrane, cell wall, and replicons. Themes that not only determine the body-plan and physical properties but also set the boundaries for choice of life style and evolution of the organisms. READ MORE
