Latest Escherichia coli Stories
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 sugars...
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 sources can contribute...
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...
It has been the cause of infamous international foodborne disease outbreaks and yet it is the most studied bacterium in science, an essential part of the human digestive tract, and a backbone of the biotech industry. To enhance public understanding of the bacterium Escherichia coli, the American Academy of Microbiology brought together the nation's leading experts to consider and answer some of the most frequently asked questions about this multifaceted microorganism. "The story of E....
LANSING, Mich., Nov. 7, 2011 /PRNewswire/ -- Neogen Corporation (Nasdaq: NEOG) has developed an even quicker method to rapidly and accurately detect yeast and mold in food products. Neogen's new Soleris(®) test detects yeast and mold in 48 hours or less -- conventional methods take up to 5 days. Tests for yeast and mold comprise approximately 15% of all microbiological tests performed worldwide. While it does not present the acute health threats of foodborne pathogens, spoilage caused...

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...
