  2. 6. Characterization and persistence of potential human pathogenic vibrios in aquatic environments

    Author : Betty Collin; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microbiology; Vibrio spp.; Mozambique; Sweden; Mytilus edulis; Vibrio cholerae; Vibrio parahaemolyticus; persistence;

    Abstract : Vibrio spp., natural inhabitants of aquatic environments, are one of the most common causes of bacterial gastroenteritis in the world, being spread to humans via the ingestion of seafood, contaminated drinking water or exposure to seawater. The majority of Vibrio spp. are avirulent, but certain strains may sporadically be human pathogenic. READ MORE

  4. 7. Structural and functional studies of the secreted metalloprotease PrtV from Vibrio cholerae

    Author : Aaron Edwin; Elisabeth Sauer-Eriksson; Helena Berglund; Umeå universitet; []
    Keywords : Cholera; Vibrio cholerae; virulence factors; PrtV; X-ray crystallography; NMR;

    Abstract : Cholera, an acute diarrheal diseases caused by the intestinal infection of the pathogenic bacterium Vibrio cholerae, continues to be a global killer in the world today. PrtV, a secreted zinc metalloprotease, is a potent cytotoxic virulence factor of V. cholerae. READ MORE

  5. 8. Development of novel vaccine strains of Vibrio cholerae and studies on the role of serotype in epidemic spread of cholera

    Author : Stefan Karlsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cholera; Vibrio cholerae; Serotype; Ogawa; Inaba; Hikojima; Vaccine; Immunogenicity; serotype switching; wbeT;

    Abstract : Cholera, caused by bacterium Vibrio cholerae O1, is a severe diarrheal disease with an estimated 3-5 million cases and more than 140 000 deaths every year particularly affecting children under 5 years of age. It can be found all over the world and often causes cholera in places where access to clean water or proper sanitary facilities are limited or compromised. READ MORE

  6. 9. Roles of membrane vesicles in bacterial pathogenesis

    Author : Svitlana Vdovikova; Sun Nyunt Wai; Richard Lundmark; Ann-Beth Jonsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane vesicles; autophagy; pore-forming toxin; pore formation; Listeria monocytogenes; Vibrio cholerae; virulence factor; PrtV protease; listeriolysin O; V. cholerae cytolysin; mikrobiologi; Microbiology; molekylärbiologi; Molecular Biology;

    Abstract : The production of membranous vesicles is observed to occur among organisms from all domains of the tree of life spanning prokaryotes (bacteria, archaea) and eukaryotes (plants, animals and fungi). Bacterial release of membrane-derived vesicles (MVs) has been studied most extensively in cases of Gram-negative species and implicating their outer membrane in formation of extracellular MVs.

  7. 10. A mouse model for direct evaluation of cholera vaccines

    Author : Erik Nygren; Göteborgs universitet; []
    Keywords : Vibrio cholerae; cholera vaccine; cholera toxin; LPS; anti-bacterial immunity; IgA; challenge; protection; colonization;

    Abstract : Cholera continues to be an important cause of morbidity and mortality in large parts of the developing world and is a significant negative factor for economic development. Vibrio cholerae bacteria of the O1 or O139 serogroup can cause disease due to their ability to colonize the intestine and produce an enterotoxin, cholera toxin (CT). READ MORE
