  2. 16. Ecological disturbances and emergence of resistance in the oral and gastrointestinal microflora after drug exposure

    Author : Christina Stark; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ecology antimicrobial resistance oral gastrointestinal microflora B-lactamase enzyme induction.;

    Abstract : The exposure of antimicrobial agents and antacids may disturb the ecological balance of the normal microflora. This influence often leads to decreased colonization resistance due to repression of sensitive bacteria and selection of resistant bacteria which have acquired resistance during therapy. READ MORE

  4. 17. Fluoride concentration in plaque and saliva and its effects on oral ecology after intake of fluoridated milk

    Author : Kristina Engström; Svante Twetman; Lars G Petersson; Göran Dahllöf; Umeå universitet; []
    Keywords : children; enamel; demineralisation; fluoride; lactic acid; laser fluoroscense; milk; plaque; saliva; salivary bacteria; odontologi; Odontology;

    Abstract : According to WHO, the addition of fluoride to milk could be considered as an alternative to water fluoridation for community-based caries prevention in childhood. School-based schemes in developing as well as industrial countries have demonstrated substantial benefits on oral health, but there are limited data available on the local events in the oral cavity after consumption of fluoridated milk.

  5. 18. Bad breath : prevalence, periodontal disease, microflora and inflammatory markers

    Author : Birgit Johansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Foetor ex ore; bad breath; halitophobia; oral hygiene; periodontal disease; periodontal pathogens and inflammatory markers;

    Abstract : Bad breath usually originates within the oral cavity and is believed to be associated with periodontal disease. The over all aim of the present thesis was to study periodontal conditions in subjects with bad breath as well as the prevalence of bad breath in subjects with periodontal disease. READ MORE

  6. 19. Bacteria-agglutinating glycoproteins in human saliva : an in vitro study with special reference to Streptococcus mutans

    Author : Jan Rundegren; Umeå universitet; []
    Keywords : agglutinin; glycoprotein; saliva; streptococcus mutans;

    Abstract : The activity and specificity of salivary glycoproteins (agglutinins) aggregating various human indigenous microorganisms were studied in vitro. The agglutinin reacting with a serotype c strain of Streptococcus mutans was isolated and chemically characterized.The results can be summarized as follows:1. READ MORE

  7. 20. Impact of Bifidobacterium longum and Lactobacillus acidophilus on the intestinal microflora and bioavailability of some food mutagens

    Author : Kerstin Orrhage; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The gastrointestinal microflora is a complex ecological system, normally characterised by a flexible equilibrium. The most important role of the microflora, from the point of view of the host, is probably to act in colonisation resistance against exogenous, potentially pathogenic, microorganisms. READ MORE
