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...

The aim of the study was to identify vibrio disease in Eucheuma cottonii samples which had characteristics ice-ice disease, namely thallus whitish and broken. research conducted at two locations Lombok, Ekas Bay waters Buwun Mas Village. were identified as bacteria Sekotong Marine Aquaculture Center using biochemical methods. results showed that associated with observed seaweeds. types cause ar...

Enterotoxic factor (EF) was present and could be developed in nonagglutinable vibrios, but not the permeability factor (PF). Presence of PF without EF in Vibrio parahaemolyticus is significant. Both EF and PF were absent in V. alcaligenes.

Kanagawa-positive Vibrio parahaemolyticus strains are considered to be human pathogens and are most commonly associated with summer diarrhea. Kanagawa-negative strains are most frequently isolated from the environment and are generally considered to be nonpathogens. We report a wound infection caused by a Kanagawa-negative V. parahaemolyticus strain. The infection occurred in October, an unusua...

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. ...

Psychrotrophic Kanagawa-positive marine vibrios were isolated from soft-shelled clams (Mya arenaria) collected in Yaquina Bay, Oreg. The 235 vibrio isolates obtained were screened for Gram reaction and morphology, Kanagawa reaction on Wagastsuma agar, and response to selected biochemical tests. The vibrio selected for further study was grown in broth, and the hemolysin was precipitated from a c...

Vibrio spp. are gram-negative, facultative anaerobic, non-spore-forming bacilli which are oxidase positive and halophilic bacteria widely spread in seaand brackwater worldwide. The genus Vibrio includes several foodborne pathogens which cause a spectrum of clinical conditions including septicaemia, cholera and milder forms of gastroenteritis. The species most commonly associated with foodborne ...

A vibrio isolated from the intestine of a coastal fish was identified as Vibrio hollisae by its biochemical characteristics. The isolate reacted with the gene probe for the thermostable direct hemolysin of Vibrio parahaemolyticus. The hemolysin produced by the isolate from the fish had traits identical to those of the thermostable direct hemolysin-like hemolysin produced by a clinical strain of...

The bacterium, Vibrio parahaemolyticus was isolated from 776 patients at Hat Yai Hospital in Southern Thailand from 2006 to 2010. 51.3-73.6% of the isolates were tdh (+) trh (-) and Group-specific PCR positive pandemic strains. A comparison of the number of V. parahaemolyticus isolates in this study and that from the same hospital in 2000-2005 indicates that this region of Thailandis endemic fo...

In this study, we examined the virulence factors and pathogenesis of Vibrio parahaemolyticus in Epinephelus awoara. The chemotactic motility of V. parahaemolyticus for phagocytosis and intracellular survival in fish macrophages was determined using virulence strains and low-virulence strains of V. parahaemolyticus. We found that the intracellular mean number of virulence strains of V. parahaemo...
