  1. 1. Analysis of a Filifactor Alocis genotype and its effect on pathological progress in periodontitis

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Tandläkarutbildning; Umeå universitet/Tandläkarutbildning

    Författare :Jessica Radu; Kati Heinämäki; [2021]
    Nyckelord :;

    Sammanfattning : Background: Filifactor alocis is a gram positive, obligate anaerobic rod bacterium that has shown correlation to pathogenic events that may be linked to periodontitis. Previous studies have proved the presence of so-called “rtx” toxins in F. alocis that are similar to the leukotoxin of A. actinomycetemcomitans. LÄS MER

  2. 2. Assessing cutoff values of saliva parameters and oral microbes in dental students

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för odontologi

    Sammanfattning : ABSTRACT Background: The ability to identify individual risk factors for development of caries areimportant parts in the perspective of being able to control and limit caries disease. One suchcomponent is to establish, cut-off values for normal versus not normal values of known andputative risk factors. LÄS MER

  3. 3. Characterization of Macrophage Activation Induced by Leukotoxin from Aggregatibacter actinomycetemcomitans 

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för odontologi; Umeå universitet/Institutionen för odontologi

    Författare :Niklas Sundling; Lisa Lü; [2018]
    Nyckelord :;

    Sammanfattning : ABSTRACT  Aggregatibacter actinomycetemcomitans (Aa), is a gram-negative, facultative anaerobe, non-motile coccobacilli colonizing the human oral cavity and is strongly associated with localized aggressive periodontitis (LAP). Aa possesses several virulence mechanisms, among others; Lipopolysaccharide (LPS), an endotoxin found in the outer membrane of Aa and Leukotoxin (LtxA), an exotoxin attached to the bacterial cell surface or in outer membrane vesicles and which has been correlating with periodontal disease mostly.

  4. 4. The importance of OuterMembrane Protein A in SerumResistance in Aggregatibacteractinomycetemcomitans serotype astrain D7SS

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för odontologi; Umeå universitet/Institutionen för odontologi

    Författare :Arvid Dahlstrand Rudin; John Burstedt; [2017]
    Nyckelord :Periodontal disease; Periodontitis; Aggressive periodontitis; Aggregatibacter actinomycetemcomitans; Actinobacillus actinomycetemcomitans; Escherichia coli; Virulence factors; Complement system; Outer membrane vesicles; Membrane vesicles; Outer membrane proteins; OmpA; Omp100; Omp34; Omp29.;

    Sammanfattning : The Gram-negative bacterium Aggregatibacter actinomycetemcomitans is primarily associatedwith aggressive forms of periodontal disease. Additionally, it has occasionally been found to causemetastatic infections in non-oral sites. This requires the ability to evade the bactericidal activity ofthe complement system of the humoral immune system. LÄS MER

  5. 5. Type IV secretion genes in cagE-negative Aggregatibacter actinomycetemcomitans serotype b

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Tandläkarutbildning

    Författare :Sarah Jasim; [2017]
    Nyckelord :Aggregatibacter actinomycetemcomitans;

    Sammanfattning : Aggregatibacter actinomycetemcomitans is a Gram-negative bacterium that plays an important role in the development of aggressive periodontitis. The cagE gene, which encodes a putative exotoxin, has been found to be present in highly leukotoxic serotype b strains. LÄS MER
