  1. 1. Chemical attenuation of bacterial virulence small molecule inhibitors of type III secretion

    University dissertation from Umeå : Kemi

    Author : Anna Kauppi; Mikael Elofsson; Anders Karlén; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; antibiotic resistance; virulence; type III secretion; T3SS inhibitors; Yop; SMD; QSAR; screening; Yersinia pseudotuberculosis; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi;

    Abstract : Despite the large arsenal of antibiotics available on the market, treatment of bacterial infections becomes more challenging in view of the fact that microbes develop resistance against existing drugs. There is an obvious need for novel drugs acting on both old and new targets in bacteria. READ MORE

  2. 2. Foodborne Virulence: Staphylococcus aureus Enterotoxins A and D

    University dissertation from Lund University

    Author : Nina Wallin; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental factors; phage-encoded virulence; in vivo; enterotoxin D; enterotoxin A; gene expression; Staphylococcus aureus; virulence;

    Abstract : The development of new, minimally processed food products challenges traditional concepts of food safety. How pathogenic bacteria behave in these new matrices is not known. To fill this knowledge gap and enable the production of food that is safe for the consumer, more information on virulence expression of pathogens in food matrices is required. READ MORE

  3. 3. Streptococcal virulence and the coagulation system

    University dissertation from Division of Infection Medicine

    Author : Kristofer Wollein Waldetoft; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococci; virulence; coagulation; intrinsic pathway; evolution;

    Abstract : This thesis explores streptococcal virulence from both mechanistic and evolutionary perspectives, where the mechanistic studies focus on interactions with the human coagulation system. We describe interactions between streptococcal surface proteins and components of the intrinsic pathway of coagulation and the kallikrein-kinin system in human plasma, as well as to how these surface proteins are produced in different growth phases.

  4. 4. Twin-arginine translocation in Yersinia the substrates and their role in virulence

    University dissertation from Umeå : Umeå University

    Author : Ummehan Avican; Åke Forsberg; Åsa Sjöling; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Yersinia pseudotuberculosis; Tat; virulence; Tat substrates; SufI; stress response; metabolism; infection; transcriptome analysis; Infectious Diseases; infektionssjukdomar; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

    Abstract : Pathogenic Yersinia cause a manifold of diseases in humans ranging from mild gastroenteritis (Y. pseudotuberculosis and Y. enterocolitica) to pneumonic and bubonic plague (Y. READ MORE

  5. 5. The impact of Staphylococcus aureus surface proteins on virulence

    University dissertation from Umeå : Umeå University

    Author : Niklas Palmqvist; Göteborgs universitet.; Gothenburg University.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Staphylococcus aureus; septic arthritis; sepsis; virulence; cell wall-anchored proteins; surface proteins; fibrinogen.;

    Abstract : Staphylococcus aureus is an important pathogen in humans with the potential to cause life-threatening invasive infections, including sepsis and septic arthritis. The pathogenicity of S. aureus depends on the expression of a variety of virulence factors. READ MORE
