Introduction It is well known that Vibrio species constitute an important percentage of the heterothrophic bacteria associated with marine bivalves, especially oysters, mussels and clams. Several Vibrio species can be pathogenic and are associated with disease outbreaks, therefore the accurate identification of these microorganisms is important. Vibrio spledidus has been found to be a dominant ...

The Ibis T5000 is a novel diagnostic platform that couples PCR and mass spectrometry. In this study, we developed an assay that can identify all known pathogenic Vibrio species and field-tested it using natural water samples from both freshwater lakes and the Georgian coastal zone of the Black Sea. Of the 278 total water samples screened, 9 different Vibrio species were detected, 114 (41%) samp...

Bacteria from the genus Vibrio are a common and environmentally important group of bacteria within coastal environments and include species pathogenic to aquaculture organisms. Their distribution and abundance are linked to specific environmental parameters, including temperature, salinity and nutrient enrichment. Accurate and efficient detection of Vibrios in environmental samples provides a p...

vibrio species are the major seafood-borne bacteria that are frequently associated with the consumption of contaminated sea food. a total of 113 samples including 58 fish and 55 shrimps were studied for the possible contamination with vibrio species. a biochemical protocol was applied for the identification of the vibrio isolates and polymerase chain reaction (pcr) was carried out to confirm th...

Species in the genus Vibrio exhibit flagellar (H) antigens unique to the species. Thus, species-specific H antiserum could be a valuable reagent with which to screen serologically large numbers of Vibrio isolates. Antisera against V. cholerae, V. fluvialis, V. anguillarum, V. metschnikovii, V. parahaemolyticus, V. alginolyticus, and V. vulnificus H antigens was produced in rabbits by repeated i...

The biological effects of supernates obtained from different strains of Vibrio alginolyticus and Vibrio anguillarum isolated from diseased fish have been studied by inoculation on two fish species, eel and rainbow trout, and two fish cell lines. These supernates possess neuroexcitatory properties, and so, when they are injected into both fish species, they trigger convulsions, wriggling, contor...

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...

Vibrio vulnificus biotype 1, a causative agent of fatal septicemia or wound infection in humans, is known to produce a toxic metalloprotease as an important virulence determinant. V. vulnificus biotype 2 (serovar E), a primary eel pathogen, was found to elaborate an extracellular metalloprotease that was indistinguishable from that of biotype 1. The potential of V. vulnificus biotype 1 for prod...

Bacteria in the genus Vibrio produce extracellular proteolytic enzymes to obtain nutrients via digestion of various protein substrates. However, the enzymes secreted by human pathogenic species have been documented to modulate the bacterial virulence. Several species including Vibrio cholerae and V. vulnificus are known to produce thermolysin-like metalloproteases termed vibriolysin. The vibrio...
