  1. 1. Outer membrane proteins of Yersinia pestis : Ail and OmpA

    Författare :Sara Celinda Schesser Bartra; Hans Wolf-Watz; Virginia Miller; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia pestis; outer membrane proteins; Ail; ompA; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; immunologi; Immunology; mikrobiologi; Microbiology; Infectious Diseases; infektionssjukdomar;

    Sammanfattning : A vast number of studies have been completed on the virulence determinants of Yersinia spp.; however, the focus of many of these studies has been on the virulence plasmid and the plasmid-encoded Type three secretion system. Nevertheless, many chromosomal genes whose products are directly involved in virulence have also been identified. LÄS MER

  3. 2. Periodontitis in adolescents : presence of Aggregatibacter species and interactions with the host

    Författare :Mark Lindholm; Jan Oscarsson; Anders Johansson; Carola Höglund-Åberg; Eija Könönen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregatibacter actinomycetemcomitans; Aggregatibacter aphrophilus; periodontitis; adolescents; OmpA; outer membrane vesicles; serum resistance; odontologi; Odontology;

    Sammanfattning : Aggregatibacter actinomycetemcomitans and Aggregatibacter aphrophilus are closely related gram-negative bacteria mainly found in the oral cavity. Periodontitis in adolescents is associated with the presence of A. actinomycetemcomitans, but not with the presence of A. aphrophilus. LÄS MER

  4. 3. Gene fusion in protein engineering : design of novel peptides and bifunctional enzymes

    Författare :Sarah Fredriksson; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cadmium; Bifunctional enzyme; Catalytic triad; Channeling; Coenzyme recycling; Galactose dehydrogenase; ß-Galactosidase; Gene fusion; Hexapeptide; Lactate dehydrogenase; Linker region; Multifunctional enzymes; Oligomeric protein; NADH; Phage; OmpA; Biochemistry; Biokemi; metabolism; Biotechnology; Bioteknik;

    Sammanfattning : The gene fusion technique is widely used in protein engineering and in this thesis it constitutes the basis of both the construction of artificial bifunctional enzymes and the display of two novel peptides. Artificial bifunctional enzymes have been used as model systems in the studies of native multifunctional enzymes and proximity effects within these complexes. LÄS MER

  5. 4. Macromolecular Matchmaking : Mechanisms and Biology of Bacterial Small RNAs

    Författare :Erik Holmqvist; E. Gerhart H. Wagner; Udo Bläsi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Small RNA; sRNA; non-coding RNA; antisense; gene regulation; post-transcriptional regulation; translational control; outer membrane protein; OmpA; MicA; biofilm; flagella; curli; bistability; Lrp; MicF; CsgD; FlgM; OmrA; OmrB; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Cells sense the properties of the surrounding environment and convert this information into changes in gene expression. Bacteria are, in contrast to many multi-cellular eukaryotes, remarkable in their ability to cope with rapid environmental changes and to endure harsh and extreme milieus. LÄS MER

  7. 5. Molecular detection of Vibrio cholerae and protozoa from water and interaction of V. cholerae clinical isolates with Acanthamoeba castellanii

    Författare :Salah Shanan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Microbial contamination of water is a major public concern due to outbreaks of cholera, giardiasis and cryptosporidiosis. Despite this, a large number of bacteria, protozoa and viruses can be found in water. LÄS MER
