  1. 1. Chromosomal β-lactamases in enterobacteria and in vivo evolution of β-lactam resistance

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Sven Bergström; Umeå universitet.; [1983]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gram negative bacteria; ß-lactamase genes; divergence of neighbouring cperons; ß-lactamase hyperproduction; evolution of control sequences;

    Sammanfattning : The ß-lactam antibiotics are the most important antibacterial agents in the treatment of infectious diseases. A severe problem in ß-lactam therapy is the emergence of ß-lactam resistant bacteria. Clinical ß-lactam resistance is most often due to the production of ß-lactamases. ß-lactamase genes reside either on plasmids or on the chromosome. LÄS MER

  2. 2. Studies on two bacterial resistance mechanisms to ß-lactam antibiot : extended spectrum ß-lactamases in Klebsiella oxytoca and methicillin resistance in staphylococci

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Laboratory Medicine

    Författare :Shang Wei Wu; Karolinska Institutet.; Karolinska Institutet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Eleven clinical isolates of Klebsiella oxytoca from Stockholm hospitals were found to be resistant to aztreonam and cefuroxime (MIC > 16 mg/L). The resistance was caused by a ß-lactamase with pI 5.25 and designated KH. Assay of the substrate profiles revealed that the KH ß-lactarnase was similar to the chromosomally encoded OXY-2 ß-lactamase. LÄS MER

  3. 3. Studies of Carbohydrate-Binding Proteins from Enterotoxigenic Escherichia coli

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Laboratory Medicine

    Författare :Lena Jansson; Göteborgs universitet.; Gothenburg University.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carbohydrate recognition; ETEC colonization factors; CFA I fimbriae; CS6 protein; heat-labile enterotoxin;

    Sammanfattning : Knowledge about the carbohydrate binding specificity of pathogens can give an increased understanding of their virulence strategies, and is also of importance for the development of anti-adhesive therapies and vaccines. Enterotoxigenic Escherichia coli (ETEC) is a well-known causative agent of diarrheal disease. LÄS MER
