  1. 36. Pathogenecity-associated genes modulate Escherichia coli adhesion and motility

    Författare :Annika E. Sjöström; Bernt Eric Uhlin; Ann-Beth Jonsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Escherichia coli strains typical of UPEC (uropathogenic E. coli) and NBM (newborn meningitis) isolates carry chromosomally located PAIs (pathogenicity islands) that are absent in non-pathogenic E. coli strains. The PAIs include genes for virulence factors such as toxins and genes coding for specific adhesins and pili/fimbriae formation. LÄS MER

  3. 37. A study of bacterial adhesion on a single-cell level by means of force measuring optical tweezers and simulations

    Författare :Oscar Björnham; Staffan Schedin; Ove Axner; Kirstine Berg-Sörensen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; fysik; Physics; cell research; cellforskning; molecular cell biology; molekylär cellbiologi;

    Sammanfattning : The intriguing world of microbiology is nowadays accessible for detailed exploration at a single–molecular level. Optical tweezers are a novel instrument that allows for non–invasive manipulation of single cells by the sole use of laser light and operates on the nano– and micrometer scale which corresponds to the same length scale as living cells.

    Sammanfattning : Inflammatory bowel diseases, (IBD), are a group of chronic disorders of the gastro-intestinal tract, and include Crohn’s disease (CD) and Ulcerative Colitis (UC). The pathogenesis is not known, but involves at least in part a loss of tolerance towards the commensal colonic microbiota. LÄS MER

  5. 39. Innate immunity in Staphylococcus aureus arthritis and sepsis

    Författare :Margareta Verdrengh; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Staphylococcus aureus; mice; sepsis; septic arthritis; neutrophils; monocytes macrophages; GM-CSF; adhesion molecules;

    Sammanfattning : Bacterial arthritis is a severe, rapidly progressing erosive disease with high morbidity and mortality. Staphylococcus aureus is the most common causative bacterium. Granulocytes together with cells from the monocyte/macrophage lineage, are the earliest leukocytes entering the synovial tissue in response to invading staphylococci. LÄS MER

  7. 40. Influence of host and bacterial factors during Neisseria meningitidis colonization

    Författare :Sara Sigurlásdóttir; Ann-Beth Jonsson; Ute Römling; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Colonization; Host-bacteria interactions; Lactate; Biofilms; Polynucleotide phosphorylase; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : 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. LÄS MER
