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.

Three-drug strategy effective against drug-resistant staph infection, finds new research

Three antibiotics that, individually, are not effective against a drug-resistant staph infection can kill the deadly pathogen when combined as a trio, according to new research.

Researchers now have a way to study special proteins linked to different diseases, cancer

Researchers from Northwestern University and Yale University have developed a user-friendly technology to help scientists understand how proteins work and fix them when they are broken. Such knowledge could pave the way for new drugs for a myriad of diseases, including cancer.

Pitt scientists find faster method to identify pathogens

There are plenty of ways in the lab to determine which bug is bugging you when you're sick. The University of Pittsburgh's Xinyu Liu, Sanford Asher, and colleagues may have found a faster method.

Bacterial litmus test provides low-cost method to measure blood micronutrients

A bacterium engineered to produce different pigments in response to varying levels of a micronutrient in blood samples could give health officials an inexpensive way to detect nutritional deficiencies in resource-limited areas of the world.

KAIST scientists predict how biological circuits sustain rhythms

Our bodies have a variety of biological clocks that follow rhythms or oscillations with periods ranging from seconds to days. For example, our hearts beat every second, and cells divide periodically. The circadian clock located in the hypothalamus generates twenty-four hour rhythms, timing our sleep and hormone release.

Research: Mechanisms behind bacterial warfare could be harnessed to target pathogenic bacteria

Two UC Santa Barbara graduate students have demonstrated how certain microbes exploit proteins in nearby bacteria to deliver toxins and kill them.

Flu remedies can help treat E. coli bacteria

If the intestinal bacteria level becomes unbalanced, it can cause diseases. Physiologists from the University of Zurich reveal how a specific carbohydrate in the intestinal mucosa heavily multiplies certain E. coli bacteria and thus causes inflammations. These could be treated with flu remedies, which opens up new therapeutic possibilities.

Wyss Institute scientists develop improved blood-cleansing therapeutic device to treat sepsis

Last year, a Wyss Institute team of scientists described the development of a new device to treat sepsis that works by mimicking our spleen. It cleanses pathogens and toxins from blood circulating through a dialysis-like circuit. Now, the Wyss Institute team has developed an improved device that synergizes with conventional antibiotic therapies and that has been streamlined to better position it for near-term translation to the clinic.

New research explores underlying mechanisms by which bacteria acquire antibiotic resistance genes

A scientific peek into bacteria boudoirs is revealing how "sex" among disease-causing microbes can lead different species or strains to become resistant to antibiotic medications.

NYU Polytechnic School of Engineering researcher awarded grant to advance protein hydrogels that mimic nature

The U.S. Army Research Laboratory's Army Research Office recently awarded a New York University Polytechnic School of Engineering researcher a grant to advance protein-engineered, environmentally responsive hydrogels that could replicate biochemical processes currently found only in nature. These protein hydrogels could become fundamental building blocks of important new biomimetic materials.

Researchers describe new Lab-on-a-Disc device for fast and reliable diagnostics of urinary tract infections

Urinary tract infections can quickly move from being a merely miserable experience to a life-threatening condition. Untreated cases may trigger sepsis, which occurs when the immune system, in an attempt to fight off the infection, inadvertently activates body-wide inflammation that can cause blood clots and leaky blood vessels.

New biosensors detect efficient microbial workers that produce chemical, pharmaceutical commodities

Super productive factories of the future could employ fleets of genetically engineered bacterial cells, such as common E. coli, to produce valuable chemical commodities in an environmentally friendly way.

UBC scientists reveal new weapon to combat malnutrition

UBC scientists have opened the doors to new research into malnutrition by creating an animal model that replicates the imbalance of gut bacteria associated with the difficult-to-treat disease.

Scientists chemically synthesize ECA-derived oligosaccharides relevant for immunotherapy

Immunotherapy using monoclonal antibodies is a promising treatment strategy, and it might now be within reach: American scientists have successfully prepared an oligosaccharide enterobacterial antigen for which a monoclonal antibody has been developed. The study is published in the journal Angewandte Chemie.

Study shows why candidate vaccine used in HVTN 505 clinical trial not protective against HIV infection

A study by researchers at the National Institute of Allergy and Infectious Diseases and Duke University helps explain why the candidate vaccine used in the HVTN 505 clinical trial was not protective against HIV infection despite robustly inducing anti-HIV antibodies: the vaccine stimulated antibodies that recognized HIV as well as microbes commonly found in the intestinal tract, part of the body's microbiome.

Discovery could put individuals with relapsing UTIs on fast track for new therapeutic regimen

It's one thing to grow bacteria in a test tube, perform a screen in the lab, and find a mutation in the pathogen's genes. It's a whole other thing, and much rarer, to find the exact same mutation in nature--in this case, in E. coli in urine samples from some 500 patients suffering from relapsing urinary tract infections.

DigiPath Labs, Romer Labs to validate kit-based assays for food-borne pathogen, mycotoxin testing for cannabis

DigiPath Labs, the cannabis testing subsidiary of DigiPath, Inc., is combining efforts with True North Laboratory of Ann Arbor, Michigan, and Romer Labs, a leading global supplier of diagnostic solutions for food-borne pathogens, to investigate the applicability of utilizing Romer Labs' rapid diagnostic test kits to screen for food-borne pathogens and quantify mycotoxins present in cannabis.

Study points to potential treatment for thrombotic thrombocytopenic purpura

A rare autoimmune disease creates sudden pain in the abdomen or the head, sending a patient to the emergency room with a potentially fatal condition. The pain comes from a multitude of blockages of tiny blood vessels, formed after the patient's own immune system somehow inhibits an enzyme that is vital to control clotting.

Duke study finds that gut worms can protect babies' brains from chronic inflammation

A Duke University study in rats finds that gut worms can protect babies' brains from long-term learning and memory problems caused by newborn infections.
