  1. 6. 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

  3. 7. Studies on experimental anaerobic infections of the middle ear and on the polymorphonuclear leukocyte function under anaerobic conditions

    Författare :Magnus Thore; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otitismedia; anaerobicbacteria; experimental; nitroimidazoles; antibody; phagocytosis; anaerobiosis;

    Sammanfattning : Despite the clinical importance of anaerobic bacteria in otitis media and the uncertainty regarding the proper treatment of the anaerobic focal infection, few experimental studies focused upon the role of these microorganisms in otitis media have been publis­hed. In the present investigation a guinea-pig model for the induc­tion of anaerobic monoinfections in the middle ear was described. LÄS MER

  4. 8. Incidence, emergence, persistence and mechanisms of antimicrobial resistance : in clinical isolates and normal microbiota

    Författare :Sonja Löfmark; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The increasing resistance rate to antimicrobial agents is of global concern and needs to be readily addressed. Options for successful treatments of infectious diseases are becoming limited due to the spread of resistant strains and resistance genes in the clinic and in the community. LÄS MER

  5. 9. Aspects of the inflammatory response and formation of polys in the nasal and sinus mucosa

    Författare :Tomas Norlander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Experimental sinusitis was induced in rabbits by ostial occlusion, with or without subsequent inoculation of Streptococcus pneumoniae, Staphylococcus aureus or Bacteroides fragilis The general inflammatory response, including goblet cell differentiation and polyp formation, was morphologically investigated. Polyps were experimentally induced by a combining mechanical trauma the mucosa with infection or by injection of agarose or N-formyl-methionyl-leucyl-phenylalanine (FMLP) into the maxillary sinus.

  7. 10. Studies on the molecular mechanisms of resistance to fluoroquinolones and carbapenems in selected bacterial species

    Författare :Nagwa Mustafa El Amin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The emergence of mutant bacteria with multi-resistant phenotype, no longer responsive to any of the available therapeutic agents is a growing concern. We have investigated the resistance mechanisms to two classes of antibacterials with broad spectrum of activity, carbapenems and fluoroquinolones. LÄS MER
