Vibrio are a genus of marine bacteria that have substantial environmental and human health importance, and there is evidence that their impact may be increasing as a consequence of changing environmental conditions. We investigated the abundance and composition of the Vibrio community within the Sydney Harbour estuary, one of the most densely populated coastal areas in Australia, and a region c...

Vibrios and other enteric pathogens can be found in wastewater effluents of a healthy population. We assessed the prevalence of three non-cholerae vibrios in wastewater effluents of 14 wastewater treatment plants (WWTP) in Chris Hani and Amathole district municipalities in the Eastern Cape Province of South Africa for a period of 12 months. With the exception of WWTP10 where presumptive vibrios...

Background and Objectives: Vibrio parahaemolyticus is the causative agent of gastroenteritis due to consumption of contaminated seafood. The aim of the present study was to determine the chemical composition of Essential Oils (EOs) of five plants (Artemisia absinthium, Zataria multiflora Boiss., Pulicaria gnaphalodes, Trachyspermum ammi and Cuminum cyminum) and to evaluate their antimicrobial a...

This review highlighted the following: (i) pathogenic mechanism of the thermostable direct hemolysin produced by Vibrio parahaemolyticus, especially on its cardiotoxicity, (ii) heat-labile and heat-stable enterotoxins produced by enterotoxigenic Escherichia coli, especially structure-activity relationship of heat-stable enterotoxin, (iii) RNA N-glycosidase activity of Vero toxins (VT1 and VT2) ...

Vaname (L. vannamei ) shrimp cultivation is currently experiencing problems, one of which disease caused by Vibrio bacteria, especially V. parahaemolyticus. This type vibrio the cause white feces and AHPND in shrimp. Disease control due to can be done utilizing plants that have active compounds as natural antibacterials are environmentally friendly. Mangrove several great potential antibacteria...

Vibrio parahaemolyticus is a well-recognized pathogen of humans. To better understand the ecology of the human-pathogenic variants of this bacterium in the environment, a study on the prevalence in bivalves of pathogenic variants (tlh+ and tdh+ and/or trh+) versus a non-pathogenic one (only tlh+ as species marker for V. parahaemolyticus), was performed in two bays in Catalonia, Spain. Environme...

UNLABELLED In the summer of 2010, Vibrio parahaemolyticus caused an outbreak in Maryland linked to the consumption of oysters. Strains isolated from both stool and oyster samples were indistinguishable by pulsed-field gel electrophoresis (PFGE). However, the oysters contained other potentially pathogenic V. parahaemolyticus strains exhibiting different PFGE patterns. In order to assess the iden...

Reports from state health departments and the Centers for Disease Control and Prevention indicate that the annual number of reported human vibriosis cases in New England has increased in the past decade. Concurrently, there has been a shift in both the spatial distribution and seasonal detection of Vibrio spp. throughout the region based on limited monitoring data. To determine environmental fa...

Vibrio parahaemolyticus, as a vibriosis, causes huge losses to the aquaculture industry, food poisoning in humans and activates macrophages induce pro-inflammatory cytokines. Chloroquine (CQ), an anti-inflammatory property, this study aimed investigate effect of CQ on inflammatory response V. parahaemolyticus RAW 264.7 macrophages. The result showed that induced production T-cell co-stimulatory...
