The infection by the cholera toxin finally leads to expulsion of sodium chloride from the body along with 10-12 litres of water in a day.
Another dangerous trend noticed in recent years in some clinical isolates of V. cholerae is the acquisition of resistance to common antibiotics, thus rendering them useless in controlling the pathogen.

 Texas Department of State Health Services, Infectious Disease Control Unit > Fact Sheet
Agent: Vibrio cholerae, a gram-negative comma-shaped rod, would serve as an effective biological weapon if the organisms were used to contaminate a large supply of the drinking water or food.
cholerae may be asymptomatic (75%), have mild diarrhea (18%), moderate diarrhea (5%), or fulminant disease (2%) characterized by sudden onset of vomiting and abdominal distension followed by profuse watery diarrhea.
Since few persons in a non-endemic area would have immunity to cholera, in the event of deliberate contamination one would expect to see all age groups affected, with the very old and very young being more seriously ill.

To the Editor: The SXT element is a Vibrio cholerae-derived ICE (integrating and conjugative element), which has also been referred to as a conjugative transposon (1) or a constin (2).
SXT element was originally isolated in 1993 from a V. cholerae O39 clinical isolate (SX[T.sup.MO210]) (1).
In contrast, in El Tor O1 V. cholerae strains isolated in India and Bangladesh, the resistance genes are located in SX[T.sup.ET], which is closely related but not identical to SX[T.sup.MO10] (2).

The complete genome of Vibrio cholerae El Tor N16961 consists of two circular chromosomes (2,961,146 and 1,072,313 base pair) with 3,890 predicted open reading frames (2,775 and 1,115 on each chromosome respectively).
The small chromosome contains a large percentage of hypothetical genes, more genes that appear to have origins other than the _ Proteobacteria, a gene capture system (integron island) that suggests this may have been a megaplasmid captured by an ancestral Vibrio species.
The Vibrio cholerae genome sequence provides a starting point for undersanding how a free living, environmental microorganism is also a human pathogen.
