Vibrio genera

Vibrio (i) Curved, rod-shaped bacterial cell, (ii) Bacterium of the genus Vibrio. Virion Virus particle the virus nucleic acid surrounded by protein coat and in some cases other material. 

A third group of bacteria are the curved or bent rods. Of these, the genus Vibrio is composed of bacteria that arc comma-shaped and die genus Spirillum consists of those that are twisted and spiral in form. All members... 

The genus Vibrio in the family of Vibrionaceae includes many species, of which V. cholerae, V. vulnificus, V. parahaemolyticus are well known human pathogens. Around 200 serogroups of V. cholerae have been identified, and 14 have been identified in V. parahaemolyticus. 

The above findings indicate that marine bacteria belonging to the genus Vibrio, more specifically V. alginolyticus, are more frequently and abundantly available in toxic marine animals and more capable of producing TTX and/or related derivatives than others. 

The horseshoe crab Ldmulus) suffers from a disease caused by the genus Vibrio which causes fatal intravascular clotting. This observation led to the realisation that the amoebocytes collected from the haemolymph of the crab contained a reactive protein (known as LAL), which could be released by lysis in distilled water. The LAL reagent is specific for the endotoxin of Gram-negative bacteria. This endotoxin is the lipopolysaccharide (LPS) fraction, and it is the lipid portion which reacts with LAL.

Many chaetognaths host bacteria of the genus Vibrio, which confer on them toxicity due to the presence of tetrodotoxin (Thuesen and Kogure, 1989). Bioluminescence has also been reported (Haddock and Case, 1994). The chitin of the hooks of species of Sagitta is a-chitin, the most common form among arthropods and fungi (Bone, Ryan, and Pulsford, 1983 Saito et al, 1995). 

Indeed, if the effects of spirolides in humans reflect those in animals, such minor effects are not to be expected, but rather paralysis and death. Pinnatoxins have been isolated from shellfish of fhe genus Pinna. Several outbreaks of poisoning have been reported in Japan and China among individuals consuming Pinna species [31,33], An association between toxicity of the shellfish and the presence of the pinnatoxins therein has not, however, been established. Indeed, the poisoning incidents were initially ascribed to contamination of the shellfish by Vibrio spp. [31].

In rivers containing large numbers of bacteria, parasite vibrios of the genus Bdellovibrio are common. These monoflagellated vibrios attach to Gram-negative bacteria, penetrate the envelope and internally parasitise the host. Polysaccharide capsules appear to provide little protection to the host. However rough mutants of Salmonellae typhimurium and E. coli (i.e. 

Another pathogen of animal origin taxonomically only related to the Enterobacteriaceae that may play a role in food-borne enteritis is the genus Campylobacter, previously indicated as Vibrio fetus. Similarly to Salmonella and Yersinia it is found in rats, swine and chickens ", and may thus enter the chain of infection typical for foods of animal origin.
