  1. 1. The role of the Type IV pili system in the virulence of Francisella tularensis

    Författare :Emelie Salomonsson; Åke Forsberg; Jean-Pierre Gorvel; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Francisella tularensis; tularemia; bacterial pathogenesis; Type IV pili; Type II secretion; Neisseria gonorrhoeae; PilA; RD18; RD19; Molecular biology; Molekylärbiologi;

    Sammanfattning : Francisella tularensis is a Gram-negative intracellular pathogen causing the zoonotic disease tularemia. F. tularensis can be found almost all over the world and has been recovered from several animal species, even though the natural reservoir of the bacterium and parts of its life cycle are still unknown.

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

    Författare :Jens Eriksson; Ann-Beth Jonsson; Helena Aro; Tone Tønjum; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria; Virulence factors; Type IV pili; PilT; PilU; NafA; NhhA; Twitching motility; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Neisseria gonorrhoeae and Neisseria meningitidis are two closely related human specific pathogens. Neisseria gonorrhoeae is the causative agent for the sexually transmitted disease gonorrhea and often causes asymptomatic infections in women which is a cause of infertility. LÄS MER

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

    Författare :Anna-Lena Forslund; Åke Forsberg; Elisabeth Carniel; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Francisella tularensis; regulation; virulence; Hfq; DsbA; type IV pili; membrane; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : 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. LÄS MER

  5. 5. Pathogenic Neisseria : Single cell motility, multicellular dynamics and antimicrobial susceptibility

    Författare :Olaspers Sara Eriksson; Ann-Beth Jonsson; Matthew Francis; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria; Type IV pili; Twitching motility; PilT; Microcolony dynamics; PilU; NafA; Antimicrobial peptide; Cell-penetrating peptide; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Neisseria meningitidis and Neisseria gonorrhoeae can colonize humans without causing any symptoms. However, gonorrhea and invasive meningococcal disease are serious health concerns. An essential virulence factor for neisserial adhesion to host cells, twitching motility and microcolony formation/aggregation is the retractile type IV pili (Tfp). LÄS MER
