  1. 21. Effect of virulence factors on survival strategies of vibrio cholerae and vibrio mimicus

    Författare :Soni Priya Valeru; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Vibrio cholerae;

    Sammanfattning : Vibrio is a genus of gram-negative bacteria comprising nearly 70 species and they are clinically human pathogens that can cause many infections. This study is mainly based on two species such as Vibrio cholerae O1 El Tor, which cause cholera disease and Vibrio mimicus, that cause gastroenteritis, open wounds infection, and septicemia.

  3. 22. Bacteria and cancer : from toxin delivery to carcinogenesis

    Författare :Riccardo Guidi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Epidemiological evidence link certain chronic bacterial infections to a higher risk of cancer development. Induction of an inflammatory circuit and the accumulation of genomic instability are considered mechanisms by which bacteria contribute to malignant transformation. LÄS MER

  4. 23. Staphylococcus aureus alpha-toxin : natural fragments and effects on intestinal epithelial cells

    Författare :Young-Keun Kwak; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Staphylococcus aureus is a human pathogen, commonly found in healthy humans as a part of normal flora. alpha-toxin is thought to be largely responsible for the pathogenesis of the bacterium. LÄS MER

  5. 24. Molecular analysis of transcription factors in uropathogenic E. coli adhesin operons

    Författare :Stina Lindberg; Bernt Eric Uhlin; Åsa Sjöling; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; UPEC; E. coli; F1C; P fimbriae; cross-talk; FocB; PapB; crystal structure; OMVs; Medical microbiology; Medicinsk mikrobiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The main causative agent of human urinary tract infections is the uropathogenic Escherichia coli (UPEC) pathotype. It may cause disease due to its ability to express a number of bacterial virulence factors. Fimbrial adhesins are particularly important for the initial establishment of infection in the urinary tract. LÄS MER

  7. 25. Survival strategies of the human respiratory tract pathogen Haemophilus influenzae

    Författare :Teresia Hallström; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mycology; Mikrobiologi; bakteriologi; bacteriology; virology; Haemophilus influenzae; IgD-binding; protein structure of Hsf; Microbiology; The complement system; virologi; mykologi;

    Sammanfattning : Haemophilus influenzae is an important respiratory tract pathogen responsible for a variety of infections in humans. Encapsulated H. influenzae belongs to one of six serotypes (a-f), of which type b is the most virulent one causing serious and sometimes life-threatening diseases (e.g. LÄS MER
