  1. 6. Acanthamoeba castellanii as a host and model to study bacterial virulence

    Författare :Amir Saeed; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Vibrio cholerae is the causative agent of cholera, a waterborne diarrheal disease and it is believed to be strictly extracellular bacterium. Cholera remains as a global public health threat affecting most of the developing world. In endemic areas, women and children are among the high risk. Recently outbreaks are reported from many countries. LÄS MER

  3. 7. Microbial ecology and virulence gene studies of the insect pathogen Bacillus thuringiensis

    Författare :Katarina Eskils; Malte Hermansson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

    Sammanfattning : Bacillus thuringiensis (Bt) is a spore-forming bacterium used as a bio-pesticide due to its insect toxicity. Bt was used as a model organism in a risk evaluation project. Prevalence, survival and spreading, as well as genome stability, putative virulence genes, and gene transfer were examined. Field release of a marked Bt subsp. LÄS MER

  4. 8. Outer membrane proteins of Yersinia pestis : Ail and OmpA

    Författare :Sara Celinda Schesser Bartra; Hans Wolf-Watz; Virginia Miller; Umeå universitet; []

    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

  5. 9. Bloodstream infections with ESBL-producing Enterobacterales : prediction, rapid diagnosis and molecular epidemiology

    Författare :Inga Fröding; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Antimicrobial-resistant bacteria are a threat to public health worldwide. Particularly, the increase of extended-spectrum β-lactamase (ESBL)-producing Enterobacterales (EPE) is a significant clinical problem. ESBLs confer resistance to cephalosporins and carbapenemases confer resistance to carbapenems. LÄS MER

  7. 10. Exploring the mechanistic details of Gram-positive Type 4 Secretion Systems

    Författare :Lena Lassinantti; Ronnie Berntsson; A. Elisabeth Sauer-Eriksson; Sjoerd Wanrooij; Samuel Wagner; Umeå universitet; []
