Vibrio parahaemolyticus is the leading bacterial cause of seafood-related gastroenteritis in the world. Here, we report the complete genome sequence and annotation of an environmental strain of V. parahaemolyticus, UCM-V493, with the aim of understanding the differences between the clinical and environmental isolates of the bacteria. We also make some preliminary sequence comparisons with the c...

The present study used pulsed-field gel electrophoresis (PFGE) characterization to examine the intraspecies variability and genetic relationships among environmental isolates of Vibrio parahaemolyticus from different European countries. This is first study performed on environmental V. parahaemolyticus that included more than one European country.

We report the whole-genome sequence of a tdh- and trh-negative Vibrio parahaemolyticus strain, V110, from shrimp. The major difference of V110 from clinical strains was its lack of the type III secretion system T3SS2, a key component of virulence. Further sequence comparison can shed light on the pathogenesis of V. parahaemolyticus.

The occurrence of various Vibrio species in water, sediment and shrimp samples from multiple shrimp farm environments from the east and west coast of India was studied. The relative abundance was higher in west coast farms (ca. 10(4) cfu/ml water) when compared to the east coast (ca. 10(2) cfu/ml water). Vibrio alginolyticus (3-19%), V. parahaemolyticus (2-13%), V. harveyi (1-7%) and V. vulnifi...

AIMS To develop a multiplex PCR targeting the gyrB and pntA genes for Vibrio species differentiation. METHODS AND RESULTS Four pairs of primers targeting gyrB gene of Vibrios at genus level and pntA gene of Vibrio cholerae, Vibrio parahaemolyticus, Vibrio vulnificus were designed. This PCR method precisely identified 250 Vibrio species and demonstrated sensitivity in the range of 4 x 10(4) CF...

In 2009, an outbreak of Vibrio parahaemolyticus occurred in Piura, Cajamarca, Lambayeque, and Lima, Peru. Whole-genome sequencing of clinical and environmental samples from the outbreak revealed a new V. parahaemolyticus clone. All the isolates identified belonged to a single clonal complex described exclusively in Asia before its emergence in Peru.

Vibrio parahaemolyticus is the leading cause of seafood-borne infections in the United States. We report complete genome sequences for two V. parahaemolyticus strains isolated in 2007, CDC_K4557 and FDA_R31 of clinical and oyster origin, respectively. These two sequences might assist in the investigation of differential virulence of this organism.

Vibrio parahaemolyticus is a clinically important foodborne pathogen that causes acute gastroenteritis worldwide. It has been shown that horizontal gene transfer (HGT) contributes significantly to virulence development of V. parahaemolyticus. In this study, we identified a novel znuA homolog (vpa1307) that belongs to a novel subfamily of ZnuA, a bacterial zinc transporter. The vpa1307 gene is l...

It is known that some strains of Vibrio parahaemolyticus are responsible for gastroenteric diseases caused by the ingestion of marine organisms contaminated with these bacterial strains. Organic products that show inhibitory activity on the growth of the pathogenic V. parahaemolyticus were extracted from a Vibrio native in the north of Chile. The inhibitory organic products were isolated by rev...

A previous investigation using the Fur titration assay system showed that Vibrio parahaemolyticus possesses a gene encoding a protein homologous to IutA, the outer-membrane receptor for ferric aerobactin in Escherichia coli. In this study, a 5.6 kb DNA region from the V. parahaemolyticus WP1 genome was cloned and two entire genes, iutA and alcD homologues, were identified which are absent from ...
