Salt water relay minimizes Vibrio A joint study by local oyster growers and researchers at the Virginia Institute of Marine Science shows that moving farmed oysters into saltier waters just prior to harvest nearly eliminates the presence of a bacterium that can sicken humans. The findings"”reported by VIMS professors Kim Reece and Howard Kator, and local oyster growers Thomas Gallivan, A.J. Erskine, and Tommy Leggett"”may offer a relatively low-cost solution to a controversial...

With cholera on the rampage in Haiti and almost 40 other countries, scientists are reporting the development of a key advance that could provide a fast, simple test to detect the toxin that causes the disease. The report appears in ACS' journal Bioconjugate Chemistry. Cholera affects more than 200,000 people annually, mainly in developing countries, and causes about 5,000 deaths. Many involve infants, children, and the elderly. J. Manuel Perez and colleagues note that cholera is an intestinal...

New clinical strains of cholera appear to have evolved a distinctly different mechanism to cause the same disease according to research published in the current issue of the online journal mBio®. Vibrio cholerae is the causative agent for the diarrheal disease cholera. While there are more than 200 different serogroups only the O1 and the O139 strains have been known to cause epidemic and pandemic outbreaks of disease, using a toxin-coregulated pilus (TCP) and cholera toxin...

In deep ocean waters, it's sometimes difficult to hide from predators. That's why so many sea creatures have evolved extraordinary methods of disguise. Cephalopods, such as octopus, squid and cuttlefish, are big on camouflage, by day or night. In fact, the Hawaiian bobtail squid has several means of stealthy self- preservation. "During the day, if they are disturbed from the sand, they will come out, sit on the surface with a sand coat on them, trying to be invisible," says Margaret...

Scientists are investigating impact of oil spill on vibrios and their antibiotic association with phytoplankton Mississippi Sound. Port Fourchon. Cocodrie. Three places among dozens in the Gulf of Mexico where oyster beds have thrived. How are the oysters faring with the oil spill? The National Science Foundation (NSF) has awarded a rapid response grant to scientists Crystal Johnson, Gary King and Ed Laws of Louisiana State University (LSU) to find out. The researchers will look at how the...

In a new study, Dartmouth researchers describe the structure of a protein called ToxT that controls the virulent nature of Vibrio cholerae, the bacteria that causes cholera. Buried within ToxT, the researchers were surprised to find a fatty acid that appears to inhibit ToxT, which prevents the bacteria from causing cholera. Cholera, which causes acute diarrhea, can be life threatening, and, according to the World Health Organization, cholera remains a serious threat to global health. Doctors...

SILVER SPRING, Md., Nov. 13 /PRNewswire-USNewswire/ -- Several weeks ago, the FDA announced its intent to change, by summer 2011, its policy regarding the post-harvest processing of raw Gulf Coast oysters harvested in the warmer months. The intent of this change in policy, which would affect about 25% of the total annual harvest, would be to substantially reduce the number of Americans who suffer severe and painful illness and death from the Vibrio vulnificus bacteria. The FDA's announced...

River discharge and regional climate are keys Cholera, an acute diarrheal disease caused by the bacterium Vibrio cholerae, has reemerged as a global killer. Outbreaks typically occur once a year in Africa and Latin America. But in Bangladesh the epidemics occur twice a year "“ in the spring and again in the fall. Scientists have tried, without much success, to determine the cause of these unique dual outbreaks "“ and advance early detection and prevention efforts "“ by...

Vibrio vulnificus is a species of Gram-negative, motile, curved, rod-shaped bacteria of the Vibrio Genus. Hollis et al. first reported it in 1976. It was given the name Beneckea vulnifica by Reichelt et al. in 1976 and in 1979 Vibrio vulnificus by Farmer. V. vulnificus is related to V. cholerae and is present in marine environments such as estuaries, brackish ponds, or coastal areas. It causes an infection often incurred after eating seafood, especially raw or undercooked oysters. It can...

Vibrio parahaemolyticus is a curved, rod-shaped, Gram-negative bacterium found in brackish saltwater, which, when ingested, causes gastrointestinal illness in humans. V. parahaemolyticus is oxidase positive, facultatively aerobic, and does not form spores. This species is motile, with a single, polar flagellum. Ingestion of raw or undercooked seafood is the most common cause of the acute gastroenteritis caused by V. parahaemolyticus. Infection can also occur from fecal-oral route as well...

Vibrio cholerae is a gram negative comma-shaped bacterium with a polar flagellum that causes cholera in humans. V. cholerae belongs to the gamma subdivision of the Proteobacteria. Classical and El Tor are the two types of V. Cholerae identified by hemaggluttination testing. El Tor is found throughout the world, while the classical biotype is found only in Bangladesh. It was first isolated as the cause of cholera by Italian anatomist Filippo Pacini in 1854; however, this discovery was not...
