Geoffrey Chang, a structural biologist at the University of California, San diego, says that the findings are very similar to those for the MATE protein from Vibrio cholerae, the bacterium that causes cholera.

shows that one toxin linked to cholera and other diseases, which hones in on a popular and plentiful protein target,

cholera (Vibrio cholera), septicemia or gastroenteritis from eating infected raw oysters (Vibrio vulnificus) and gastric illnesses that threaten people with weakened immune systems (Aeromonas hydrophila.

Extensive testing at UVA labs show that the tablet causes better than a 99.99 percent reduction in such infectious waterborne bacteria as Vibrio cholera

#Cholera Bacteria Spear Their Prey to Grab Genes The bacteria that cause cholera grab genes from other organisms in a particularly predatory way, new research finds.

But researchers at The swiss Federal Institute of technology in Lausanne, Switzerland, found that cholera (formally called Vibrio cholerae) have a unique way of doing so.

Cholera is usually found in water and it feeds on chitin, the stuff that makes up crustaceans'shells.

and the cholera bacterium absorbs the freed genetic material. The 9 Deadliest Viruses On earth Making these spikes in itself isn't that unusual,

This is, however, the first time anyone has observed cholera bacteria or any bacteria using this system to gather up new genes.

Cholera makes people sick when it is ingested. The bacteria gets to the small intestine and then multiplies, producing proteins that are toxic to humans and cause watery diarrhea.

cholera can be deadly. Humans can build immunity to some strains of cholera. But sometimes, new strains appear,

and the transfer of genes from other species of bacteria (including other kinds of cholera) might be one reason these new strains arrive."

"That's what we think what we see is part of what makes the most virulent strains so virulent,

Not every kind of cell can contribute DNA to cholera, as there has to be some similarity between the cholera cell and its victim,

Blokesch said. Even so, some genes might alter the outer membrane of the bacteria, for example, making it less visible to the human immune system or tougher for people's stomach acid to kill.

This kind of gene transfer might well have been involved in a cholera epidemic that hit Southeast asia in the early 1990s

Blokesch added that the spearing mechanism might be one more reason the cholera bacterium is so virulent in the human gut.

Cholera might be spearing neighboring cells, killing them and exacerbating the problems it causes. Cholera won't pick up human DNA,

however, because it is too different.)The study appears today (Jan 1) in the journal Science S

and are considered often to be our enemies, causing many diseases such as tuberculosis or cholera. However, they can also be witnessed allies,

who runs this lab. He says 800,000 children a year die from these diseases notably cholera, rotavirus and certain strains of E coli."

and are considered often to be our enemies, causing many diseases such as tuberculosis or cholera. However, they can also be witnessed allies,

but now hope to create particles capable of killing off pathogens such as Clostridium difficile and the cholera-causing bacterium Vibrio cholerea.

While the technology has already been proven to be capable of rapidly detecting cholera it took graphene to also make it sensitive to cancer. e showed experimentally that simply the addition of graphene led to a clear increase in the sensor signal, aid Dr. Georg Duesberg,

The sensor has shown yet its value in detecting cholera without error, and, as the authors wrote in the current study,
