What Are the Early Signs of Vibrio Infection? If the wound becomes infected, it's important to tell your health care provider about any exposure to salt water, raw seafood, or seafood juices. If an open wound does come into contact with brackish water (or raw seafood), wash it thoroughly with soap and water. It’s also wise to avoid swimming in salt water if you’re suffering from an open cut or sore. The authors of a review article in Frontiers in Microbiology reference studies that show this Vibrio species was found in "3.5–8% of seafood samples in Europe, 2.4% of shrimp from Southeast Asia, 75% of freshly harvested oysters in India, and 100% of oysters harvested from the Gulf of Mexico during warm months." vulnificus, try to avoid raw oyster consumption or eating any shellfish that has not been thoroughly cooked. Additionally, those who have undergone recent stomach surgery may be at an increased risk. While anyone can contract a Vibrio infection, the condition is more common in those with compromised immune systems or liver diseases. However, skin infections also occur if an individual with an open wound is exposed to salt water.Īccording to the CDC, living in hurricane-prone regions is a high-risk factor for a vulnificus infection due to exposure to coastal water, particularly between the months of May and October, when water temperatures are warmer (9° to 31 ☌). vulnificus as a result of consuming raw or undercooked shellfish, such as raw oysters. If you think you may be suffering from a vulnificus infection, don’t hesitate to seek immediate medical attention. Vibrio vulnificus strikes approximately 205 Americans each year and is the main cause of seafood-related deaths. vulnificus dies, and others require intensive care or even limb amputation. According to the Centers for Disease Control and Prevention (CDC), one in seven people with V. It’s important to note that a Vibrio infection is a serious condition. vulnificus, patients can suffer an array of symptoms ranging from serious gastroenteritis (from consuming affected seafood) to soft tissue infections and necrotizing fasciitis, also known as flesh-eating bacteria. First discovered in 1979, this Vibri o species is common in the Gulf of Mexico as well as parts of the East and West Coasts of the United States, including the Gulf Coast region comprising Alabama, Florida, Louisiana, Texas, and Mississippi. Flood, “ Chloride capture using a C–H hydrogen bonding cage.” Science 23, eaaw5145 (2019).Affecting humans and primates, Vibrio vulnificus is a type of gram-negative bacterium found in warm, shallow coastal water. acknowledges support from the Waterman Professorship. The Department of Energy, Office of Science, Office of Basic Energy Sciences, Chemical Sciences, Geosciences, and Biosciences division funded this research. This rigid molecular cage holds promise for water purification and potentially other applications. Compared to cages made with stronger bonds, the new cage performs several orders of magnitude better. The team made the molecular cage using carbon-hydrogen bonds, which are weaker than typical nitrogen-hydrogen bonds. This gives the molecule greater efficacy and versatility. The rigidity also enables the molecule to retain its shape after the central chloride has been lost, compared to other designs that collapse under the same circumstances due to their flexibility. Now, researchers have designed a rigid molecular cage that draws in chloride ions. Researchers have looked at flexible molecular cages to capture the chloride. Many of these salts contain chloride ions. The challenge is to remove the salts quickly and efficiently. These solids pollute the water, making it undrinkable. freshwater streams per year, according to estimates by the U.S. SummaryĪbout 272 metric tons of dissolved solids, including salts, enter U.S. The research and the resulting molecular cage could help increase the amount of drinkable water on Earth. It takes just one teaspoon of salt to permanently pollute five gallons of water. Salts come from oil extraction, road salts, water softeners, and the natural weathering of rock. Salts seeping into freshwater streams and lakes reduce access to drinkable water across the globe. The new salt-extraction molecule is composed of six triazole motifs, which together form a 3-D cage perfectly shaped to trap chloride. It binds chloride using carbon-hydrogen bonds, previously regarded as too weak to create stable interactions with chloride. Built using chemical bonds previously regarded as too weak, the new molecule is highly effective. Researchers devised a powerful new molecule for the extraction of salt from liquid.
