    Sammanfattning : Aggregatibacter actinomycetemcomitans is an oral bacterium that is mainly associated with aggressive forms of periodontitis, which most often starts at an early age. Amongst the virulence factors of A. LÄS MER

  2. 2. Inflammatory cell death of human macrophages induced by Aggregatibacter actinomycetemcomitans leukotoxin

    Detta är en avhandling från Umeå : Institutionen för odontologi

    Författare :Peyman Kelk; Umeå universitet.; Umeå universitet.; [2009]

    Sammanfattning : Aggregatibacter (Actinobacillus) actinomycetemcomitans is a bacterium mainly associated with aggressive forms of periodontitis. Among its virulence factors, a leukotoxin is suggested to play an important role in the pathogenicity. LÄS MER

  3. 3. Vesicle-independent extracellular release and bioactivity of peptidoglycan-associated lipoprotein from Aggregatibacter actinomycetemcomitans

    Detta är en avhandling från Umeå : Odontologi

    Författare :Maribasappa Karched; Umeå universitet.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peptidoglycan-associated lipoprotein; outer membrane proteins; immunoproteomics; periodontitis; cytokines; Aggregatibacter actinomycetemcomitans.; ODONTOLOGY Oral microbiology; ODONTOLOGI Oral mikrobiologi;

    Sammanfattning : Aggregatibacter (Actinobacillus) actinomycetemcomitans is a Gram-negative coccobacillus of the Pasteurellaceae family. It is implicated in periodontitis, a common low-grade bacterial infection, but it can also cause non-oral infections. The main aim of this project was to identify and characterize in A. LÄS MER

  4. 4. Vesicle-mediated and free soluble delivery of bacterial effector proteins by oral and systemic pathogens

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Bernard Thay; Umeå universitet.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Periodontitis; Aggregatibacter actinomycetemcomitans; Staphylococcus aureus; membrane vesicles; vesicle-host cell interaction; protein delivery; molekylärbiologi; Molecular Biology;

    Sammanfattning : Periodontitis, the primary cause of tooth-loss worldwide, is a bacterially induced chronic inflammatory disease of the periodontium. It is associated with systemic conditions such as cardiovascular disease (CVD). However, pathogenic mechanisms of periodontitis-associated bacteria that may contribute to the CVD association are unclear. LÄS MER

  5. 5. Outer membrane vesicle-mediated export of virulence factors from Gram-negative bacteria

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Pramod Kumar Rompikuntal; Umeå universitet.; [2012]
