چکیده

We investigated the virulence properties of four Vibrio parahaemolyticus strains causing acute gastroenteritis following consumption of indigenous mussels in Italy. The isolated strains were cytotoxic and adhesive but, surprisingly, lacked tdh, trh, and type three secretion system 2 (T3SS2) genes. We emphasize that nontoxigenic V. parahaemolyticus can induce acute gastroenteritis, highlighting the need for more investigation of the pathogenicity of this microorganism.

Urea-hydrolyzing Vibrio parahaemolyticus associated with acute gastroenteritis.

A case of gastroenteritis caused by a urea-hydrolyzing strain of Vibrio parahaemolyticus is presented. Urea-hydrolyzing strains of Vibrio parahaemolyticus have rarely been reported and have not been described previously as a cause of gastroenteritis in the United States. With the exception of urea hydrolysis and the methyl red test, the isolate had all the characteristics of V. parahaemolyticus...

Irregular virulence genes expression of Vibrio parahaemolyticus in shrimp or seawater matrix

Vibrio parahaemolyticus is a gram-negative marine bacterium which is a natural inhabitant of marine and estuarine environments around the world. It has been perceived as a major cause of food-borne illness characterized by acute gastroenteritis, mainly due to consumption of raw or undercooked contaminated seafood [1,2]. Furthermore, V. parahaemolyticus infection is a growing public health conce...

Investigation of Reference Genes in Vibrio parahaemolyticus for Gene Expression Analysis Using Quantitative RT-PCR

Vibrio parahaemolyticus is a significant human pathogen capable of causing foodborne gastroenteritis associated with the consumption of contaminated raw or undercooked seafood. Quantitative RT-PCR (qRT-PCR) is a useful tool for studying gene expression in V. parahaemolyticus to characterize its virulence factors and understand the effect of environmental conditions on its pathogenicity. However...

Draft Genome Sequences of Four Vibrio parahaemolyticus Isolates from Clinical Cases in Canada

Vibrio parahaemolyticus is a leading cause of bacterial gastroenteritis following ingestion of contaminated seafood. This report presents the draft genome sequences of four clinical strains of V. parahaemolyticus isolated in Canada. All four strains lack traditional pathogenic markers and possess uniquely individual characteristics identified using other typing criteria.
