1. 1. ADHESION OF AGGREGATIBACTER ACTINOMYCETEMCOMITANS AND STREPTOCOCCUS MUTANS ANALYZED WITH DNA-BASED METHODS

   University essay from Umeå universitet/Institutionen för odontologi

   Author : Jud Tirawiyeh; Fartun Ali; [2023]
   Keywords : A. actinomycetemcomitans; S. mutans; DNA-based qPCR; adhesion; epithelial cells; plant extracts;

   Abstract : Oral health is a part of general health and the two are connected in many ways as well as impact each other. Oral diseases are some of the most common chronic diseases of mankind. Diseases such as caries and periodontitis are two of the most common ones affecting the oral cavity. READ MORE

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

   University essay from Umeå universitet/Tandläkarutbildning

   Author : Jessica Radu; Kati Heinämäki; [2021]
   Keywords : ;

   Abstract : 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. READ MORE

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

   University essay from Umeå universitet/Institutionen för odontologi

   Author : Peter Germann; [2020]
   Keywords : ;

   Abstract : 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. READ MORE

5. 4. Characterization of Macrophage Activation Induced by Leukotoxin from Aggregatibacter actinomycetemcomitans 

   University essay from Umeå universitet/Institutionen för odontologi

   Author : Niklas Sundling; Lisa Lü; [2018]
   Keywords : ;

   Abstract : 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.

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

   University essay from Umeå universitet/Institutionen för odontologi

   Author : Arvid Dahlstrand Rudin; John Burstedt; [2017]
   Keywords : 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.;

   Abstract : 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. READ MORE
