NEW ORLEANS, Oct. 15 /PRNewswire/ -- To The Editor: Recent deaths of consumers in Florida and Texas caused by bacterial infections in shellfish should remind people with certain pre-existing conditions of health risks associated with consuming raw shellfish, particularly during warm weather when waters in the Gulf of Mexico are especially susceptible to the growth of Vibrio vulnificus bacteria. Vibrio vulnificus is a naturally occurring bacteria completely unrelated to pollution. Although...
Scientists in the USA have established a way to predict outbreaks of cholera, making it easier to control. This finding could provide a model to predict and potentially control outbreaks of other important infectious diseases.Cholera is a serious, ancient water-borne infectious disease, which is an unpredictable and severe problem for developing countries.The bacterium that causes cholera, Vibrio cholerae, has a known association with a crustacean (called a copepod) which lives on...
WASHINGTON (Reuters) - U.S. health officials added a warning about clams on Friday to their caution against eating raw oysters from the Pacific Northwest following more reports of stomach sickness caused by bacteria from the shellfish. Seventy-two illnesses linked to contaminated oysters and clams were reported from May 20 through July 31, the Food and Drug Administration said. Another 105 probable cases were recorded during the same time period. The illnesses were reported in...
WASHINGTON (Reuters) - Consumers should avoid eating raw oysters harvested from the Pacific Northwest, U.S. health officials warned on Monday after reports of stomach illnesses linked to bacterial contamination. The U.S. Food and Drug Administration said a growing number of people, mostly in Washington state, have reported getting sick after eating oysters tainted with the Vibrio parahaemolyticus bacterium.

By Gene Emery BOSTON (Reuters) - Warming ocean waters may have tainted Alaskan oysters with a bacteria that triggered four outbreaks of illness on a cruise ship among people who ate the shellfish raw, researchers reported on Wednesday. "The rising temperatures of ocean water seem to have contributed to one of the largest known outbreaks of Vibrio parahaemolyticus in the United States," said Joseph McLaughlin of the Alaska Department of Health and Social Services, referring to the...
NEW ORLEANS -- The most outrageous rumor was the report about two dogs poisoned by the toxic floodwaters that filled many New Orleans neighborhoods.At the start of the flooding, as the waters of already less-than-pristine Lake Pontchartrain poured through collapsed levees into low-lying areas, health experts and environmentalists feared the flood would break open chemical tanks, barrels of oil, and solvents.They worried that sitting floodwaters could dissolve the contents of buried hazardous...
NEW ORLEANS (Reuters) - Investigators searching for evidence of epidemics following Hurricane Katrina found plenty of stomach upset but no serious outbreaks -- yet. "We haven't seen anything that jumps off the page," said Dr. Carolyn Tabak. "But there are illnesses that seem to be occurring in greater numbers." Tabak, a pediatrician at the National Center for Health Statistics in Hyattsville, Maryland, is helping lead a team of researchers who will decide if any epidemics have followed...
By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Three people have died from bacterial infections in Gulf states after Hurricane Katrina, and tests confirm that the water flooding New Orleans is a stew of sewage-borne bacteria, federal officials said on Wednesday. A fourth person in the Gulf region is suspected to be infected with Vibrio vulnificus, a common marine bacteria, Centers for Disease Control and Prevention Director Dr. Julie Gerberding told reporters,...
WASHINGTON (Reuters) - Three people have died from suspected bacterial infections caused by the dirty water that Hurricane Katrina drove ashore last week, the U.S. Centers for Disease Control and Prevention said on Wednesday.The CDC initially said it had reports that up to five people had died, but CDC Director Dr. Julie Gerberding said three had died and another one was ill.The patients, possibly evacuees, were infected with Vibrio vulnificus bacteria, a water-borne pathogen that is related...

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...
