    Abstract : Popular Abstract in Swedish Uppskattningsvis 30 % av befolkningen i industrialiserade länder drabbas varje år av förgiftningar och infektioner överförda via livsmedel och frekvensen i utvecklingsländer tros vara högre. För att kunna producera säker mat behövs mer kunskap om vilka egenskaper hos livsmedelsburna patogener, dvs. READ MORE

  2. 2. Identification of new virulence factors in Francisella tularensis

    University dissertation from Umeå : Institutionen för Molekylärbiologi, Umeå universitet

    Author : Anna-Lena Forslund; Umeå universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Francisella tularensis; regulation; virulence; Hfq; DsbA; type IV pili; membrane; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Francisella tularensis, the causative agent of tularemia, is a highly virulent bacterium with an infection dose of less than ten bacteria. The ability of a pathogen to cause infection relies on different virulence mechanisms, but in Francisella tularensis relatively few virulence factors are known. Two F. READ MORE

  3. 3. Virulence Factors and Motility Mechanisms of Pathogenic Neisseria

    University dissertation from Stockholm : Department of Genetics, Microbiology and Toxicology, Stockholm University

    Abstract : The common human pathogen Streptococcus pyogenes is the causative agent of numerous mild and severe clinical conditions. It expresses a number of secreted or cell wall-anchored proteins that modulate the human immune system and facilitate colonization and spread of the pathogen in the human host. During S. READ MORE
