New wireless sensor device rapidly detects E. coli in water samples Fecal contamination of public beaches caused by sewage overflow is both dangerous for swimmers and costly for state and local economies. Current methods to detect Escherichia coli, a bacterium highly indicative of the presence of fecal matter in water, typically require 24-48 hours to produce a result. A new, accurate, and economical sensor-based device capable of measuring E. coli levels in water samples in less than 1-8...

In a paper published in the December 2011 issue of Experimental Biology and Medicine, a team of scientists at the University of Illinois, Urbana-Champaign led by Rex Gaskins, PhD have demonstrated that both microbial and host inflammatory factors modulate sulfomucin production in a human cell line, LS174T, that models intestinal goblet cells. Sulfomucins, one of two primary types of acidomucins secreted by intestinal goblet cells, provide crucial protection to the intestinal mucosa....

Understanding mechanism may aid in development of infection-fighting drugs In the human world of manufacturing, many companies are now applying an on-demand, just-in-time strategy to conserve resources, reduce costs and promote production of goods precisely when and where they are most needed. A recent study from Indiana University Bloomington scientists reveals that bacteria have evolved a similar just-in-time strategy to constrain production of an extremely sticky cement to exactly the...

Researchers at the Hebrew University of Jerusalem and the University of Vienna have revealed for the first time a stress-induced machinery of protein synthesis that is involved in bringing about cell death in bacteria. Their work opens a new chapter in the understanding of protein synthesis under stress conditions, which are the conditions bacteria usually are faced with, both in humans and otherwise in nature, and could pave the way for the design of novel, new antibiotics that would help...

Joint BioEnergy Institute (JBEI) Researchers Reach Milestone on the Road to Biofuels A milestone has been reached on the road to developing advanced biofuels that can replace gasoline, diesel and jet fuels with a domestically-produced clean, green, renewable alternative. Researchers with the U.S. Department of Energy (DOE)´s Joint BioEnergy Institute (JBEI) have engineered the first strains of  Escherichia coli bacteria that can digest switchgrass biomass and synthesize its...

Abnormal levels of caffeine in water indicate human contamination Researchers led by Prof. Sébastien Sauvé of the University of Montreal's Department of Chemistry have discovered that traces of caffeine are a useful indicator of the contamination of our water by sewers. "E coli bacteria is commonly used to evaluate and regulate the levels of fecal pollution of our water from storm water discharge, but because storm sewers systems collect surface runoff, non-human...

New publication demonstrates ability of Avidocin proteins to prevent and treat E. coli O157 diarrhea in animal study A novel antibacterial protein targeted against E. coli O157:H7 may offer a way to prevent or treat serious food-borne bacterial infections, as demonstrated in a study published in the December issue of Antimicrobial Agents and Chemotherapy. Results in an animal model of E. coli infection showed that the orally administered protein, developed by AvidBiotics, Inc., could...

Researchers discover role of H2S as defense mechanism against oxidative stress and antibiotics Although scientists have known for centuries that many bacteria produce hydrogen sulfide (H2S) it was thought to be simply a toxic by-product of cellular activity. Now, researchers at NYU School of Medicine have discovered H2S in fact plays a major role in protecting bacteria from the effects of numerous different antibiotics. In the study led by Evgeny Nudler, PhD, the Julie Wilson Anderson...

An experimental treatment for urinary tract infections has easily passed its first test in animals, alleviating weeks-long infections in mice in as little as six hours. "This drug can block the spread of the bacteria that cause urinary tract infections far better than any other previously reported compound," says senior author Scott J. Hultgren, PhD, the Helen L Stoever Professor of Molecular Microbiology at Washington University School of Medicine in St. Louis. "If it has similar effects...

Trend data follows release of first-of-its-kind 'drug resistance index' for superbugs New research suggests a pattern of outpatient antibiotic overuse in parts of the United States-- particularly in the Southeast --a problem that could accelerate the rate at which these powerful drugs are rendered useless, according to Extending the Cure, a project of the Center for Disease Dynamics, Economics & Policy. These findings come out just as the Centers for Disease Control and Prevention...

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...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
