    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Host-bacteria interaction; Helicobacter pylori; Neisseria gonorrhoeae; Lactobacillus; Epithelial cells; Macrophages; EGR1; Amphiregulin; SabA; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Helicobacter pylori colonizes the human stomach, where it causes gastritis that may develop into peptic ulcer disease or cancer when left untreated. Neisseria gonorrhoeae colonizes the urogenital tract and causes the sexually transmitted disease gonorrhea. READ MORE

  4. 2. Influence of host and bacterial factors during Neisseria meningitidis colonization

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Colonization; Host-bacteria interactions; Lactate; Biofilms; Polynucleotide phosphorylase; molekylär biovetenskap; Molecular Bioscience;

    Abstract : The human-restricted pathogen Neisseria meningitidis is a major cause of bacterial meningitis and sepsis worldwide. Colonization of the mucosal layer in the upper respiratory tract is essential to establish an asymptomatic carrier state and invasive disease. N. READ MORE

  5. 3. Evolutionary patterns and processes of bacteriophages, particularly P2-like phages

    Author : Anders Nilsson; Siv Andersson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Genetics; genetik;

    Abstract : DNA sequencing of structural genes of temperate P2-like prophages from isolates of Escherichia coli bacteria showed that the difference between these genes was very small. Separate phylogenetic analyses on the genes resulted in unresolved trees, caused by a high level of homologous recombination, which implied that homologous recombination is the most important source of new genetic variation for P2-like phages infecting E.
