  1. 1. Modulators of Vibrio cholerae predator interaction and virulence

    University dissertation from Umeå : Umeå University

    Author : Barbro Lindmark; Umeå universitet.; [2009]
    Keywords : Vibrio cholerae; Caenorhabditis elegans; PrtV; outer membrane vesicles; non-O1 non-O139; serum resistance; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Clinical genetics Molecular biology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Klinisk genetik Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Vibrio cholerae, the causal agent of cholera typically encodes two critical virulence factors: cholera toxin (CT), which is primarily responsible for the diarrhoeal purge, and toxin-co-regulated pilus (TCP), an essential colonisation factor. Nontoxigenic strains expressing TCP can efficiently acquire the CT gene through lysogenic conversion with CTXΦ, a filamentous phage that encodes CT and uses TCP as a receptor. READ MORE

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

    University dissertation from Stockholm : Karolinska Institutet, Dept of Laboratory Medicine

    Author : Soni Priya Valeru; Karolinska Institutet.; Karolinska Institutet.; [2013]

    Abstract : 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. 3. Characterization and persistence of potential human pathogenic vibrios in aquatic environments

    University dissertation from Kristianstad : Kristianstad University

    Author : Betty Collin; Högskolan Kristianstad.; Göteborgs universitet.; University of Gothenburg.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Vibrio cholerae; Vibrio parahaemolyticus; Mozambique; Sweden; molluscs; occurrence; persistence; sediment; TCBS; PCR; PhP; antibiotic resistance; microbiology; Vibrio spp.; Mytilus edulis;

    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. 4. A mouse model for direct evaluation of cholera vaccines

    University dissertation from Kristianstad : Kristianstad University

    Author : Erik Nygren; Göteborgs universitet.; University of Gothenburg.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN; MEDICINE; 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

  5. 5. Outer membrane vesicle-mediated export of virulence factors from Gram-negative bacteria

    University dissertation from Umeå : Umeå universitet

    Author : Pramod Kumar Rompikuntal; Umeå universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Outer membrane vesicles; CDT; PGN; PrtV; Campylobacter jejuni; Vibrio cholerae; Aggregatibacter actinomycetemcomitans; molekylärbiologi; Molecular Biology;

    Abstract : The Gram-negative, motile bacterium Campylobacter jejuni is a causative agent of food-borne gastroenteritis. Cytolethal distending toxin (CDT) is one of the important virulence factors for C. jejuni pathogenesis. It was not previously known how CDT is released from C. READ MORE
