Diarrheal disease remains an unsolved problem in developing countries. The emergence of new etiological agents (non-cholera vibrios) is a major cause of concern for health planners. We attempted to unveil the seasonal dynamics of entero-pathogenic Vibrios in Gangetic riverine-estuarine ecosystem. 120 surface water samples were collected for a period of one year from 3 sampling sites on the Hoog...

Extracellular proteins of wild-type Vibrio alginolyticus were compared with those of copper-resistant and copper-sensitive mutants. One copper-resistant mutant (Cu40B3) constitutively produced an extracellular protein with the same apparent molecular mass (21 kDa) and chromatographic behavior as copper-binding protein (CuBP), a copper-induced supernatant protein which has been implicated in cop...

The polar flagellum of Vibrio alginolyticus rotates remarkably fast (up to 1,700 revolutions per second) by using a motor driven by sodium ions. Two genes, motX and motY, for the sodium-driven flagellar motor have been identified in marine bacteria, Vibrio parahaemolyticus and V. alginolyticus. They have no similarity to the genes for proton-driven motors, motA and motB, whose products constitu...

The antibiotic resistance patterns of aetiological agents responsible for vibriosis and pasteurellosis were studied to contribute to control the spread of these two bacterial diseases in Mediterranean fish farming. Strains of Photobacterium damsela ssp. piscicida, Vibrio fluvialis, Vibrio alginolyticus, Vibrio parahaemolyticus, Vibrio metschnikovii, isolated from Italian aquaculture (fish, shel...

We recently found that marine bacteria Vibrio alginolyticus execute a cyclic three-step (run-reverse-flick) motility pattern that is distinctively different from the two-step (run-tumble) pattern of Escherichia coli. How this novel, to our knowledge, swimming pattern is regulated by cells of V. alginolyticus is not currently known, but its significance for bacterial chemotaxis is self-evident a...

The orange-spotted grouper (Epinephelus coioides) is an important marine farmed fish in China. It affected by the bacterial pathogen Vibrio alginolyticus, which causes high mortality and substantial economic losses. We studied transcriptional changes of IgZ gene E. coioides following V. alginolyticus stimulation investigated distribution different tissues. highest expression level occurred head...

INTRODUCTION Wound infections with Vibrio alginolyticus, a Gram-negative bacterium found in all temperate oceans, are rarely reported. However, a rising incidence of wound infections caused by V. alginolyticus requires better knowledge about this infectious agent. CASE PRESENTATION We report the case of a 14-year-old boy suffering from a wound infection caused by V. alginolyticus and Staphylo...

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 ...

In July 2011, a Vibrio alginolyticus infection was diagnosed in a woman from Guernsey in the Channel Islands, British Isles after sea bathing and application of a natural seaweed dressing to a pre-existing leg wound. Microbiological investigation confirmed Vibrio in the wound and the species of seaweed used for the dressing. The washing of open wounds in seawater and use of unsterilised seaweed...

arsenic is one of the most dangerous heavy metals in the environment that is harmful for organisms such as human beings. due to this treat economic approach for elimination of arsenic from water and wastewater is necessary. in this research arsenic-resistant bacteria from water and sediments of lake maharloo were isolated and identified then their antibiotic resistance was evaluated. sampling w...
