  1. 1. Identification of Bacteroides fragilis from clinical samples

    Författare :Guangming Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :identification; B. fragilis; enterotoxigenic B. fragilis; monoclonal antibodies; and PCR;

    Sammanfattning : The members of Bacteroides fragilis group are Gram-negative anaerobic, non-spore forming rods that are present in the normal flora of human intestine. B. fragilis group consists of ten species: B. caccae, B. LÄS MER

  3. 2. Quinolone resistance in Bacteroides fragilis and Pseudomonas aeruginosa, two opportunistic pathogens

    Författare :Herin Oh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Quinolone; resistance; B. fragilis; P. aeruginosa; topoisomerase; efflux;

    Sammanfattning : Opportunistic pathogens can cause infections in case of structural or functional defects in the host. Examples of Gram-negative opportunists are the Bacteroides fragilis group, anaerobic, non-spore forming rods and the aerobic, non-fermentative rod Pseudomonas aeruginosa. LÄS MER

  4. 3. Beta-lactam and metronidazole resistance in the Bacteroides fragilis group

    Författare :Hong Fang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Bacteroides fragilis group; beta-lactam; metronidazole; resistance; beta-lactamase; penicillinbinding proteins PBPs ; outer membrane proteins OMPs ;

    Sammanfattning : The Bacteroides fragilis group organisms are anaerobic gram-negative bacilli. Ten species are currently included in this group. Members of the B. fragilis group are the major constituents of the normal colonic microflora and the most commonly encountered anaerobic bacteria in clinical specimens. LÄS MER

  5. 4. Ecological aspects of antimicrobial susceptibility of anaerobic bacteria in Nicaragua

    Författare :Mercedes Cáceres; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Antimicrobial susceptibility; normal flora; anaerobic infections; B-lactamase; enterotoxigenic B. fragilis;

    Sammanfattning : Anaerobic bacteria are the predominant constituents of the normal flora on the skin and the mucous membranes of the human body. They may also act as potent pathogens in a variety of endogenous infections. Antimicrobial resistance is an increasing problem with anaerobic and aerobic bacteria. Different mechanisms for such resistance are known. LÄS MER

  7. 5. Ecological disturbances and emergence of resistance in the oral and gastrointestinal microflora after drug exposure

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

    Sammanfattning : 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. LÄS MER
