AIMS To describe the diversity of the culturable mesophilic and potentially pathogenic vibrios isolated at 22 and 37°C on TCBS medium, in September 2009 from seawater and surface sediments. METHODS AND RESULTS q-PCR assays previously selected for the identification of bacterial strains isolated at 37°C were used in combination with the partial sequencing of two housekeeping genes, pyrH and to...

Vibrio tubiashii is a recently reemerging pathogen of larval bivalve mollusks, causing both toxigenic and invasive disease. Marine Vibrio spp. produce an array of extracellular products as potential pathogenicity factors. Culture supernatants of V. tubiashii have been shown to be toxic to oyster larvae and were reported to contain a metalloprotease and a cytolysin/hemolysin. However, the struct...

Food contamination with extended-spectrum beta-lactamase (ESBL)-producing bacteria is recognized as one of the public health concerns worldwide. Although fish and fishery products at retail in Japan have relied on imported materials, no apparent evidences exist prevalence property genetic transfer ESBL-producing those food specimens. This study aimed to investigate plasmid-mediated antibiotic-r...

Vibrio spp. are major causes of mortality in white shrimp (Litopenaeus vannamei) which is lacking adaptive immunity. Passive immunization with a specific egg yolk antibody (IgY) is a potential method for the protection of shrimp against vibriosis. In this study, immune effects of the specific egg yolk powders (IgY) against both V. harveyi and V. parahaemolyticus on white shrimp were evaluated. ...

Despite that Vibrio spp. have a significant impact on the health of humans and aquatic animals, the molecular basis of their pathogenesis is little known, mainly due to the limited genetic tools for the functional research of genes in Vibrio. In some cases, deletion of target DNAs in Vibrio can be achieved through the use of suicide vectors. However, these strategies are time-consuming and lack...

Seafood constitutes an important food component and a cheap source of protein in developing countries. Shrimps are prone to bacterial contamination in their environment and have been frequently implicated in Vibrio parahaemolyticus infection. Of the 121 Penaeus monodon collected from coastal beaches in Douala, 79(65.3%) were contaminated with Vibrio spp. Presumed Vibrio sp. were identified by s...

During the summer of 2006, several wound infections - of which three were fatal - caused by Vibrio cholerae were reported from patients who had been exposed to water from the Baltic Sea. Before these reports, we initiated a sampling project investigating the occurrence of potential human pathogenic V. cholerae, Vibrio vulnificus and Vibrio parahaemolyticus in The Sound between Sweden and Denmar...

Four Vibrio spp. isolates from the historical culture collection at the Centers for Disease Control and Prevention, obtained from human blood specimens (n=3) and river water (n=1), show characteristics distinct from those of isolates of the most closely related species, Vibrio navarrensis and Vibrio vulnificus, based on phenotypic and genotypic tests. They are specifically adapted to survival i...

An increase in the occurrence of potentially pathogenic Vibrio species is expected for waters in Northern Europe as a consequence of global warming. In this context, a higher incidence of Vibrio infections is predicted for the future and forecasts suggest that people visiting and living at the Baltic Sea are at particular risk. This study aimed to investigate antimicrobial resistance patterns a...
