The application of effective probiotics in shrimp aquaculture is an excellent alternative for chemicals and antibiotics to prevent disease control. This study was carried out to evaluate the probiotic potential of Lactobacillus acidophilus 04 (home made curd isolate) on pathogenic Vibrio in shrimp Penaeus monodon juveniles. L. acidophilus showed antibacterial activity against Vibrio parahaemoly...

AIMS To identify Vibrio vulnificus, Vibrio cholerae and Vibrio alginolyticus using standardized DNA extraction method and real-time PCR assays, among a large number of bacterial strains isolated from marine environment. METHODS AND RESULTS Methods for DNA extraction and real-time PCR were standardized to identify a large number of Vibrio spp. strains isolated through regular collection campai...

Vibrio vulnificus and Vibrio parahaemolyticus are ubiquitous in the marine-estuarine environment, but the magnitude of human non-ingestion exposure to these waterborne pathogens is largely unknown. We evaluated the magnitude of dermal exposure to V. vulnificus and V. parahaemolyticus among swimmers recreating in Vibrio-populated waters by conducting swim studies at four swimming locations in th...

UNLABELLED Vibrio parahaemolyticus is a marine bacterium which is also responsible for acute diarrhoeal illness in human beings. Eating raw seafish or contaminated seafood is responsible for acute gastroenteritis. The aim of this study was to investigate the isolation, identification and molecular characterization of Vibrio parahaemolyticus from the fish samples in Kolkata, India. MATERIALS A...

A novel Vibrio strain, JCM 31412T, was isolated from seawater collected from the Inland Sea (Setonaikai), Japan, and characterized as a Gram-negative, oxidase-positive, catalase-negative, facultatively anaerobic, motile, ovoid-shaped bacterium with one polar flagellum. Based on 16S rDNA gene identity, strain JCM 31412T showed a close relationship with type strains of Vibrio brasiliensis (LMG 20...

Bacteria of the genus Vibrio occur at a continuum from free-living to symbiotic life forms, including opportunists and pathogens, that can contribute to severe diseases, for instance summer mortality events of Pacific oysters Crassostrea gigas. While most studies focused on Vibrio isolated from moribund oysters during mortality outbreaks, investigations of the Vibrio community in healthy oyster...

Background: Cholera, an acute diarrhoeal disease caused by Vibrio cholerae still ranks high in the etiology of diarrhoeal diseases in several parts of India. Aim:To study the characteristics and anti-microbial resistance pattern of the Vibrio choleraestrains isolated in our hospital. Methods: Over a 2 year period, stool samples from clinically suspected cholera cases were screened and the isola...

INTRODUCTION This research aimed to identify and quantify potentially pathogenic Vibrio from different cultivations of bivalve shellfish in the State of Santa Catarina, Brazil, and water regions in the South Bay, as well as correlate the incidence of these microorganisms with the physicochemical parameters of marine waters. METHODS Between October 2008 and March 2009, 60 oyster and seawater s...

The role of exogenous metabolites as putative signal molecules mediating and/or regulating the carbon starvation adaptation program in Vibrio sp. strain S14 was investigated. Addition of the stationary-phase supernatant extract (SSE) of Vibrio sp. strain S14 to logarithmic-phase cells resulted in a significant number of carbon starvation-induced proteins being up-regulated. Halogenated furanone...

We report the results from a mesocosm study investigating the interrelationship between microalgae and vibrios. The mesocosms were inoculated with plankton, plankton + sediment, or sediment. We followed the diatom bloom and increases in the abundance of Vibrio spp. and V. parahaemolyticus in conjunction with several environmental variables in all mesocosms and at a reference site. The dominatin...
