  1. 31. Parasite virulence and disease severity in Plasmodium falciparum malaria

    Författare :Ulf Ribacke; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Malaria stands out as one of the most important infectious diseases and one of the world s leading causes of death. Plasmodium falciparum is the parasite responsible for the great majority of severe disease syndromes and mortality, and affects mainly children and pregnant women. Despite intensive research efforts, the understanding of P. LÄS MER

  3. 32. The Salmonella enterica virulence : its role in bacterial adaption to mammalian and protozoan cells

    Författare :Dilek Tezcan-Merdol; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Salmonella virulence plasmid; spvB gene; mono ADP-ribosyl transferase; actin; Acanthamoeba rhysodes;

    Sammanfattning : Salmonellae are Gram-negative enteric bacteria and facultative intracellular pathogens responsible for a diversity of illnesses in a wide range of hosts, including man. Many serovars of Salmonella enterica harbor a plasmid that enhances bacterial virulence in infection models, and that seems to promote extraintestinal infection in man. LÄS MER

  4. 33. Antibiotic Resistance and Fitness of Escherichia coli in the Infantile Commensal Microbiota

    Författare :Nahid Karami; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ampicillin; tetracycline; in vivo fitness; persistence; gene transfer; intestinal; blaTEM Escherichia coli;

    Sammanfattning : Microbial resistance to antibiotics is a growing problem worldwide. Resistance develops not only in microbes which are the targets of the antibiotic treatment, but also in those belonging to the normal microbiota of the treated host. Little is known on the ecological consequences of antibiotic resistance in commensal bacteria. LÄS MER

  5. 34. Genome dynamics and virulence in the human pathogen Candida glabrata

    Författare :Khadija Mohamed Ahmad; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pathogenic yeast; Candida glabrata; small chromosomes; Genome rearrangement; Haploid and diploid yeast; RNA interference.;

    Sammanfattning : Although the yeast Candida glabrata is considered to be a part of the commensal microflora in healthy individuals, during the last years it has been frequently isolated from patients with mucosal and systemic fungal infections. Now it is considered as the second most frequently isolated pathogenic yeast after Candida albicans. Despite its name, C. LÄS MER

  7. 35. Studies on fibronectin binding proteins, proteases, and virulence in Staphylococcus aureus

    Författare :Patricia Saravia Otten; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Staphylococcus aureus produces several surface proteins, many of which bind specifically to different host extracellular matrix (ECM) proteins and plasma proteins, such as fibronectin, collagen and fibrinogen. Two highly homologous fibronectin binding proteins (FnBPA and FnBPB), enconded by fnbA and fnbB, have been characterized. LÄS MER
