  2. 1. Virulence Factors and Motility Mechanisms of Pathogenic Neisseria

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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). READ MORE

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

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

    Abstract : 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.

  6. 4. Host responses and bacterial virulence factors in Neisseria infections

    Author : Linda Johansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Neisseria; CD46; LPS; antimicrobial peptide.;

    Abstract : Neisseria meningitidis and Neisseria gonorrhoeae are human specific pathogens. N. meningitidis is a major cause of meningitis and sepsis, whilst N. gonorrhoeae causes many millions of cases of gonorrhea in the world every year. READ MORE

  7. 5. Hfq- and sRNA-mediated regulation in Neisseria meningitidis

    Author : Jens Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Neisseria meningitidis, also known as the meningococcus, is a human-specific pathogen that commonly colonises the nasopharynx without causing disease. For reasons unknown, N. meningitidis can traverse the nasopharyngeal epithelium and enter the bloodstream, causing invasive meningococcal disease manifesting in septicaemia and/or meningitis.
