a total of 116 marine fishes and sediments were collected from persian gulf shore near bushehr in order to isolate vibrio species. after culturing on thiosulphate- cirate- bile salts- sucrose and with biochemical tests, 30 isolates showed vibrio characteristics which were categorized in 7 vibrio species, v. anguillarum, v. alginalyticus, v. harveyi, v. vulnfiicus, v. ordalii, v. carchariae and ...

Different species of bacteria were tested for production of extracellular autoinducer-like activities that could stimulate the expression of the luminescence genes in Vibrio harveyi. Several species of bacteria, including the pathogens Vibrio cholerae and Vibrio parahaemolyticus, were found to produce such activities. Possible physiological roles for the two V. harveyi detection-response system...

The methanolic and aqueous extracts of Garcinia kola seeds were screened for their anti-Vibrio activities against 50 Vibrio isolates obtained from wastewater final effluents in the Eastern Cape Province, South Africa. The crude extracts at 10 mg/mL exhibited appreciable inhibitory activities against most of the test Vibrio isolates, with zones of inhibition ranging from 10-19 mm for methanol ex...

Extensive use of antimicrobial agents in finfish farming and the consequent selective pressure lead to the acquisition of antibiotic resistance in aquaculture environment bacteria. Vibrio genus represents one of the main pathogens affecting gilthead sea bream. The development of antibiotic resistance by Vibrio represents a potential threat to human health by exchange of resistant genes to human...

Vibrio species are both ubiquitous and abundant in marine coastal waters, estuaries, ocean sediment, and aquaculture settings worldwide. We report here the isolation, characterization, and genome sequence of a novel Vibrio species, Vibrio antiquarius, isolated from a mesophilic bacterial community associated with hydrothermal vents located along the East Pacific Rise, near the southwest coast o...

Vibrio are a genus of marine bacteria that have substantial environmental and human health importance, and there is evidence that their impact may be increasing as a consequence of changing environmental conditions. We investigated the abundance and composition of the Vibrio community within the Sydney Harbour estuary, one of the most densely populated coastal areas in Australia, and a region c...

Vibrios and other enteric pathogens can be found in wastewater effluents of a healthy population. We assessed the prevalence of three non-cholerae vibrios in wastewater effluents of 14 wastewater treatment plants (WWTP) in Chris Hani and Amathole district municipalities in the Eastern Cape Province of South Africa for a period of 12 months. With the exception of WWTP10 where presumptive vibrios...

Vibrio anguillarum was isolated from several organs of some aquarium catfish in a fish population with high mortality. Macroscopic examination of the affected catfish revealed ascites in the abdomen, site-petechiae, and dorsal erection. Although there are some variations in phenotypic characterization among different isolates of Vibrio anguillarum, the majority show a common biochemical profile...

Petroleum hydrocarbon contamination is a major global prevalent issue in the petroleum sector. This research focuses on evaluating biodegradation of three Gram-negative bacilli, isolated from cowpea planted soil, contaminated with kerosene. The Gram negative bacilli strains have been characterized and identified, using MicrobactTM ID24E systems for the identification of Enterobacteriaceae and c...
