Escherichia coli — a bacteria considered the food safety bane of restaurateurs, grocers and consumers — is a friend. Cornell University biomolecular engineers have learned to use E. coli to produce sugar-modified proteins for making pharmaceuticals cheaper and faster. (Nature Chemical Biology, March 25, 2012.) Matthew DeLisa, Cornell associate professor of chemical and biomolecular engineering, and his research team, now have published a novel method for engineering human...

The ripeness of fruit could determine how food-poisoning bacteria grow on them, according to scientists presenting their work at the Society for General Microbiology's Spring Conference in Dublin this week. Their work could lead to new strategies to improve food safety, bringing many health and economic benefits. A wide range of fresh produce has been linked to outbreaks of Escherichia coli and Salmonella enterica including melons, jalapeño and serrano peppers, basil,...

Food-borne diseases might soon have another warrior to contend with, thanks to a new molecule discovered by chemists at the University of Illinois. The new antibiotic, an analog of the widely used food preservative nisin, also has potential to be a boon to the dairy industry as a treatment for bovine mastitis. The antibiotic nisin occurs naturally in milk, a product of bacteria resident in the cow's udder. It helps keep milk from spoiling and kills a broad spectrum of bacteria that cause...

A  class of chemical compounds used for flavor and fragrance may one day become a clean, renewable resource with which to fuel our automobiles. U.S. Department of Energy researchers have modified the E. Coli bacteria to create large quantities of methyl ketone from glucose. First tests of this methyl ketone show very high cetane numbers. Cetane is a fuel rating system for diesel fuel, similar to octane ratings for gasoline. This makes the methyl ketones a viable candidate for production...

In the E coli outbreak in Germany in May 2011, treatment with azithromycin was associated with a lower frequency of long-term carriage of the bacteria and shorter duration of shedding of the bacteria in stool specimens, according to a study in the March 14 issue of JAMA. "Since May 2011, a large outbreak of Shiga toxin-producing Escherichia coli (STEC) has caused 3,816 documented infections in Germany, including 845 confirmed cases of hemolytic uremic syndrome [HUS; a condition...

Working in the emerging field of systems biology, UT Southwestern Medical Center researchers mathematically predicted how bacteria that cause food poisoning hijack a cell's sense of direction and then confirmed those predictions in living cells. The study proposed a new model to explain how mammalian cells establish the sense of direction necessary to move, as well as the mechanism that a disease-causing form of E. coli bacteria employ to hijack that ability. Cells need to orient...

(Ivanhoe Newswire) -- A recent study has discovered that short-term use of the antibiotic cefpodoxime for treatment of bladder infections (uncomplicated cystitis) in women did not meet criteria for achieving clinical cure compared to ciproflaxacin, a drug classified as fluoroquinolone antibiotics, that is under concern for overuse and resulting in an increase in resistance rates. While fluoroquinolone has minimal adverse drug reactions when used in a 3-day regimen and high efficacy rates,...

Synedgen Study Shows Chitosan Derivative Reduces Risk of Food Contamination. Claremont CA (PRWEB) February 11, 2012 Claremont CA, January 24, 2012--Research conducted by Synedgen Inc. and the School of Environment, Natural Resources & Geography, at Bangor University, Bangor, UK, appears in the early view of Food Control, an international, official scientific journal of the European Federation of Food Science and Technology (EFFoST) covering microbial food safety and antimicrobial...

Scientists from Queen Mary, University of London have discovered the workings behind some of the bacteria that kill hundreds of thousands every year, possibly paving the way for new antibiotics that could treat infections more effectively. With antibiotic resistance on the rise in strains of pathogenic bacteria, innovative strategies are needed to discover ways of treating bacterial infections in both humans and in agriculture. Writing in the journal PLoS Pathogens, the team from Queen...

Klebsiella pneumoniae is a Gram-negative, non-motile, encapsulated, lactose fermenting, facultative anaerobic, rod shaped bacterium found in the normal flora of the mouth, skin, and intestines. It is the most important member of the Klebsiella genus of Enterobacteriaceae. It is naturally occurring in soil and about 30% of strains can fix nitrogen in anaerobic conditions. Hans Christian Gram developed the technique now known as Gram staining in 1884 to discriminate between K. pneumoniae and...

Escherichia coli is a Gram-negative rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms. Most strains are harmless; however, some such as O157:H7 can cause food poisoning in humans and are often responsible for product recalls. The normal flora of the gut normally contains the harmless strains and often provide K2 to the body. They are not always confined to the intestine and have the ability to survive briefly outside of the body. It grows easily...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
