Analysis of Vibrio parahaemolyticus Virulence Systems
Vibrio parahaemolyticus is a Gram-negative halophilic bacterium and one of the leading causes of food-borne gastroenteritis from the consumption of raw or undercooked seafood. The pathogenicity of V. parahaemolyticus is attributed to several virulence factors, including two hemolysins and two type …

Characterization of Mitochondrially Targeted T3SS2 Effectors in Vibrio parahaemolyticus
Vibrio parahaemolyticus (V. parahaemolyticus) is a Gram-negative bacterial pathogen that is the leading cause of bacterial seafood-borne acute gastroenteritis. All strains of V. parahaemolyticus harbor the type III secretion system 1 (T3SS1), which is dispensable for virulence in humans. Pathogenic …

Studies of the genome and regulatory processes of Vibrio parahaemolyticus
Vibrio parahaemolyticus is considered to be an emerging, yet understudied, human pathogen. The V. parahaemolyticus BB22OP genome was sequenced to allow for a comparative analysis between the genome of BB22OP and another previously sequenced, pathogenic strain of V. parahaemolyticus, RIMD2210633. V. …

Tale of Two Hosts: Vibrio parahaemolyticus Toxicity Against Human and Shrimp
… genes during infection. We discovered that Vibrio parahaemolyticus VtrC, along with VtrA and VtrB, are required for activating the virulence type III secretion system 2 (T3SS2) in response to bile salts. The VtrA/VtrC complex activates VtrB in the presence of bile salts. The crystal …

Lethatlity of and Elicitation of Protective Antibody by Vibrio parahaemolyticus ATTC 17803
<p>The LD<sub>50</sub> of Vibrio parahaemolyticus ATCC 17803 for 13- to 18-g male mice, strain ICR, as determined by the 50% endpoint method, was found to be an estimated 7 x 10<sup>7 </sup>CFU, when administered intraperitoneally in 0.5 ml of 24-h broth culture, O. D. 0.5 at 650 nm, diluted to …

Development of novel methods for the detection of Vibrio parahaemolyticus in seafood
Vibrio parahaemolyticus is marine bacterium found worldwide. It is most commonly associated with seafood related gastroenteritis, but can also be found naturally occurring in the estuarine environment. Infection is most common in the summer months, when the water temperature is suitable for the …

Production and application of antibodies produced against the flagella and hemolysin of Vibrio parahaemolyticus
Vibrio parahaemolyticus is a marine bacterium which is the leading cause of bacterial gastroenteritis due to consumption of raw or undercooked bivalve molluscan shellfish in United States and is considered an important seafood-borne pathogen throughout the world. The conventional methods for …

Functional analysis of the role of alternative sigma factors in Vibrio parahaemolyticus host pathogen interactions
Vibrio parahaemolyticus, a ubiquitous Gram-negative marine bacterium, is the leading cause of bacterial seafood borne gastroenteritis in humans. This organism must adapt to both host and marine environmental stresses. One mechanism bacteria employ to respond to rapid environmental changes is the …

Analysis of the Quorum Sensing Regulons of Vibrio parahaemolyticus BB22 and Pantoea stewartii subspecies stewartii
… the two studied for this dissertation work, Vibrio parahaemolyticus and Pantoea stewartii subsp. stewartii. V. parahaemolyticus causes acute gastroenteritis in people who eat contaminated raw or undercooked shellfish. It is found in warmer marine waters and in rare cases, causes systemic …

Existing regulatory circuitries govern backbone and acquired host association factors in the human pathogen Vibrio parahaemolyticus
<p>Vibrio parahaemolyticus is a poorly characterized human gastrointestinal pathogen whose virulence mechanisms are not well understood. Though closely related to Vibrio cholerae, V. parahaemolyticus infections are inflammatory and utilize virulence traits that are unique from the Cholera toxins …

Pandemic <em>Vibrio parahaemolyticus</em>: Defining Strains Using Molecular Typing and a Growth Advantage at Lower Temperatures
Vibrio parahaemolyticus is a leading cause of seafood-borne illness with a newly emerged pandemic strain. Previous studies compared the pandemic and non-pandemic strains to understand the evolution of the pandemic strain but no definitive explanation for its emergence has been discovered. This …

Inhibiting Listeria monocytogenes, Vibrio parahaemolyticus and Morganella morganii with Aqueous Methanol Extracts of Punica granatum and Galla chinensis
Listeria monocytogenes, Vibrio parahaemolyticus and Morganella morganii are closely related to foodborne illnesses caused by the consumption of seafood and ready-to-eat (RTE) food. Traditional Chinese medicines (TCM) have been widely studied as complementary and alternative medicines, and many of …
