E. coli News and Research

RSS

E. coli or Escherichia coli is the name of a type of bacteria that lives in your intestines. Most types of E. coli are harmless. However, some types can make you sick and cause diarrhea. One type causes travelers' diarrhea. The worst type of E. coli causes bloody diarrhea, and can sometimes cause kidney failure and even death. These problems are most likely to occur in children and in adults with weak immune systems. You can get E. coli infections by eating foods containing the bacteria. To help avoid food poisoning and prevent infection, handle food safely. Cook meat well, wash fruits and vegetables before eating or cooking them, and avoid unpasteurized milk and juices. You can also get the infection by swallowing water in a swimming pool contaminated with human waste. Most cases of E. coli infection get better without treatment in 5 to 10 days.

Genomic analysis of E. coli shows multiple steps to evolve new trait

Several years ago researchers at Michigan State University (MSU) reported discovering a novel, evolutionary trait in a long-studied population of Escherichia coli, a rod-shaped bacterium commonly found in the lower intestine of mammals. The E. coli added a helping of citrate to its traditional diet of glucose, even though other E. coli can't consume citrate in the presence of oxygen.

Study finds high levels of ESBL bacteria in Danish chicken meat

Nearly half of the samples from chicken meat imported into Denmark contain ESBL bacteria and for the first time the level is almost as high in Danish chicken meat. By contrast, the occurrence in Danish pigs has decreased significantly since farmers stopped using cephalosporins for pigs.

Study finds identical strains of antibiotic-resistant C. coli in ABF and conventionally raised pigs

Researchers from North Carolina State University have found identical strains of antibiotic-resistant Campylobacter coli (C. coli) in both antibiotic-free (ABF) and conventionally raised pigs.

Synthetic biology pioneer wins 2012 Heinz Award

Jay Keasling, a leading authority and pioneer on synthetic biology who has engineered microbial "factories" to manufacture an affordable version of a frontline antimalarial drug and biofuel substitutes for gasoline, diesel and jet fuel, has won a 2012 Heinz Award, which is presented by the Heinz Family Foundation and carries with it a cash prize of $250,000.

Molecular insight into oxygen sensing mechanism

The study of an oxygen-sensing bacterial regulatory protein by chemistry researchers at the University of Georgia has provided molecular insight into the oxygen sensing mechanism, which could ultimately lead to a better understanding of the ageing process and new treatments for human diseases such cancer, Parkinson's and Alzheimer's.

Arsanis to develop monoclonal antibody therapeutics against nosocomial infections

Arsanis Biosciences GmbH, an early stage biotechnology company developing anti-infective human monoclonal antibodies, today announced the award of two major grants for the development of monoclonal antibody therapeutics against nosocomial infections.

U of I microbial engineer synthesizes 2-fucosyllactose to protect babies from pathogens

A University of Illinois microbial engineer has synthesized a sugar in human milk that is thought to protect babies from pathogens. That's important because 2FL, the shorthand scientists use to describe this human milk oligosaccharide (HMO), has not been added to infant formula because HMOs are incredibly expensive.

Simple low-cost biosensor to detect contaminated drinking water

Diarrheal disease is the second leading cause of death in children under five years old - killing as many as 1.5 million children worldwide every year. These startling statistics from the World Health Organization (2009) point to the reason why a group of undergraduate students from Arizona State University is working to develop a low-cost biosensor - a simple device that would detect contaminated drinking water.

Kalidex announces presentation of data on KPI-10 against MDR strains at ICAAC

Kalidex Pharmaceuticals, a privately-held anti-infective company, today announced the presentation of data on its lead development candidate KPI-10, a broad spectrum, next-generation fluoroquinolone, at the Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in San Francisco, September 9 through 12.

Seven antibiotic-resistance genes swapped between human and soil bacteria

Soil bacteria and bacteria that cause human diseases have recently swapped at least seven antibiotic-resistance genes, researchers at Washington University School of Medicine in St. Louis report Aug. 31 in Science.

Antibiotic residues in meat can allow pathogenic bacteria to proliferate

Antibiotic residues in uncured pepperoni or salami meat are potent enough to weaken helpful bacteria that processors add to acidify the sausage to make it safe for consumption, according to a study to be published in mBio-, the online open-access journal of the American Society for Microbiology, on August 28.

New method simplifies pharmaceutical production of proteins

Engineering researchers at the University of Arkansas have developed a method to simplify the pharmaceutical production of proteins used in drugs that treat a variety of diseases and health conditions, including diabetes, cancer, arthritis and macular degeneration.

Cholera toxin binds differently to intestinal cells than previously thought

The likelihood of becoming seriously ill from cholera depends on your blood group. It is possible to find a new remedy for the feared illness by studying the molecular structure in the toxin in the cholera bacteria.

Study explains how breast milk fosters colonies of microbiotic flora in a newborn's intestinal tract

The benefits of breast milk have long been appreciated, but now scientists at Duke University Medical Center have described a unique property that makes mother's milk better than infant formula in protecting infants from infections and illnesses.

Lunch boxes and school eating areas are hotspots for bacteria

Canadian moms earn top marks when it comes to good hygiene practices, but a new study by Lysol and the Global Hygiene Council reveals they could do more to safeguard against bacteria hotspots in schools, especially at lunch time.

Children more likely to pick up stomach infections from private water supplies

Children drinking from around half the UK's private water supplies are almost five times more likely to pick up stomach infections - according to research from the University of East Anglia (UEA).
