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.

New under-skin sensor that monitors blood sugar levels for diabetics

People with diabetes could soon be waving goodbye to the pain and hassle of needles, thanks to a new under-skin sensor that monitors blood sugar levels with a simple wave of the arm.

A natural molecule that blocks a key bacterial enzymes could lead to a new generation of antibiotics

Rutgers scientists have deciphered the complex mechanics of microcin J25 (MccJ25), a tiny, natural molecule that acts like a cork in a bottle to block a key bacterial enzyme – potentially leading to a new generation of antibiotics.

Fragranced candles can have valuable and effective bactericidal properties

In recent years the consumer market for candles has grown dramatically, as candles of all shapes, sizes, colours and fragrances have been used increasingly in homes and restaurants to create atmosphere and enhance mood.

Beef tacos with a side order of Escherichia coli

Thirteen people from Arizona, California, and Nevada who ate beef tacos from a national fast-food restaurant chain in 1999 became infected with Escherichia coli, according to a study in the June 15 issue of Clinical Infectious Diseases, now available online.

Patent issued for GHB, date rape drug test

A patent for a highly sensitive test to detect the presence of the "date rape" drug, GHB, has recently been granted to the University of California, Santa Barbara.

Computational design used to engineer and construct a protein that could sense the nerve agent soman

Duke University Medical Center biochemists have used computational design to engineer and construct a protein that could sense the nerve agent soman. They said their achievement constitutes a proof-of principle that such engineered proteins can be made to detect nerve agents such as sarin and other toxic substances.

Proteins transform DNA into molecular velcro

Proteins critical for compacting DNA in preparation for cell division actually interact with the double helix to fashion it into a kind of “molecular Velcro,” researchers have discovered.

Randomness in gene expression to lead to differences in people that are genetically identical

Experiments by Howard Hughes Medical Institute (HHMI) researchers have revealed it might be possible for randomness in gene expression to lead to differences in cells — or people, for that matter — that are genetically identical.

An antibiotic, Tigecycline produces 74 percent cure rate in cSSSI patients

An antibiotic, currently being tested in clinical trials, produced a 74 percent cure rate for hospitalized patients with possibly life-threatening, complicated skin and skin structure infections (cSSSI).

Signs of liver disease also improve in conjunction with alterations to gut flora

Some cirrhotic patients develop brain dysfunction, called hepatic encephalopathy, which causes deficits in behavior, intelligence, consciousness and neuromuscular function.

Protein in the male reproductive tract is a potent anti-bacterial agent

Scientists at the University of North Carolina at Chapel Hill have found that a protein they discovered three years ago in the male reproductive tract is a potent anti-bacterial agent.

Scientists have unraveled the behavior of one key component of bacteria

The researchers studied a mechanism of action they call the "magic spot" – an important regulator of gene expression. They describe their results in the current issue of the journal Cell.

Pennsylvania's restaurants, stadiums, bars and supermarkets are adjusting to revised food safety requirements

Pennsylvania's restaurants, stadiums, bars and supermarkets are adjusting to revised food safety requirements in the Pennsylvania Food Code, according to a specialist in Penn State's College of Agricultural Sciences.

Genetically engineered bugs to fight cancer

GENETICALLY engineered bacteria could become the latest weapons against cancer, Cancer Research UK scientists suggest in a study published today 22nd April 2004.

Poultry litter harbors agents that generate antibiotic multi-resistance

They found that poultry litter – a ubiquitous part of large broiler operations – harbors a vastly larger number of microbial agents that collect and express resistance genes than was previously known.

76 million people get sick in US, 300,000 are hospitalized, and 5,000 die from foodborne illness

Foodborne illnesses have a major public health impact in the United States. It is estimated that each year in the United States, 76 million people get sick, more than 300,000 are hospitalized, and 5,000 die as a result of foodborne illnesses, primarily the very young, elderly, and the immunocompromised.

Scientists will debate E.coli and the adaption by micro-organisms to modern day drugs

This debate will centre around why humans are constantly under attack from infectious diseases such as E.coli despite medical advances in vaccinations and antibiotics, and how micro-organisms that cause disease evolve and adapt quickly to the many barriers that our bodies' anti-infection strategies and our drugs industry throw at them.

New process to extract proteins from membranes by using chemicals

Proteins are complex compounds that are essential for the growth and repair of tissue. While scientists understand much about the structure and stability of water-soluble proteins that ‘float’ around in humans, they know very little about the shape and stability of proteins that are embedded, or folded, into the lipid membrane of cells. Such membrane proteins make up about 30 percent of all proteins in the body.

Analysis of Bacterial Genomes Begins to Unravel Complex Story of Metabolic Evolution

In a paper published in the current issue of the journal Molecular Biology and Evolution , Arizona State University biochemists Jason Raymond, Christopher Staples and Robert Blankenship and Rice University's Janet Siefert do an analysis of the genomes of a large group of bacteria and archaea, comparing in particular similar genes that produce the protein nitrogenase.

Scientists have discovered that a non-genetic molecular process can effect cell behaviour

Genetic mutations, sudden, random and usually harmful changes to the structure of a gene, are only one factor that determines the ultimate fate of a cell. Chicago scientists have discovered that a non-genetic molecular process also can play a role, and that experimenters can influence this process in bacteria, they report in the April 1 issue of the journal Nature.
