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.
Cole-Parmer Ltd announced today that Jenway®, a leading UK manufacturer of analytical laboratory instruments, has launched the new Genova Bio Life Science Spectrophotometer. The Genova Bio, a UV/visible spectrophotometer, has been designed for fast and easy use in life science applications, whilst having a low-price point.
By understanding the functional differences between proteins expressed by two E. coli strains, researchers at Kansas State University are exploring new opportunities to inhibit their impacts to human health.
Stopping a wound from bleeding is essential for human health. Blood coagulation - in which blood goes from liquid to gel and forms a clot - can prevent excessive bleeding and infection. But exactly what molecular events transpire when blood coagulates has remained somewhat mysterious.
The University of Maryland School of Medicine has been awarded a three-year, $2.47 million grant from the National Institute of Allergy and Infectious Diseases to develop a vaccine to protect against Shigella and Enterotoxigenic Escherichia coli (ETEC), pathogens which are among the leading causes of diarrheal diseases in young children in developing countries and a common cause of "traveler's diarrhea" among travelers to these countries.
Bacteria come in all shapes and sizes -- some are straight as a rod, others twist like a corkscrew. Shape plays an important role in how bacteria infiltrate and attack cells in the body.
Copper has long been known for its ability to kill bacteria and other microbes. But in an interesting twist, researchers at Washington University School of Medicine in St. Louis have shown that Escherichia coli (E. coli) bacteria - those at the root of hard-to-treat urinary tract infections (UTIs) - hijack trace amounts of copper in the body and use it as a nutrient to fuel growth.
A new study from India raises questions about the dangers to human health of farming chicken with growth-promoting antibiotics--including some of the same drugs used in raising millions of chickens in the United States and worldwide.
The first large-scale genetic study of Escherichia coli (E. coli) cultured from patients with bloodstream infections in England showed that drug resistant 'superbugs' are not always out-competing other strains.
Many animal species display flocking behavior, but the fact that microorganisms do is not as well known. Researchers at Lund University in Sweden have now shown that algae and bacteria form flocks at very low concentrations of individuals, a finding that could increase our future understanding of how the organisms infect their host animals.
CANCER researchers in the UK may have stumbled across a solution to reverse antibiotic drug resistance and stop infections like MRSA.
Scientists at Johns Hopkins, Rutgers, the University of Trento in Italy, and Harvard Medical School report they have developed a new molecular technique called LASSO cloning, which can be used to isolate thousands of long DNA sequences at the same time, more than ever before possible.
The project is headed by Senior Research Associate of the Microorganism Genetics Lab Ayrat Kayumov and funded by Russian Science Foundation and Project 5-100. The results have been published in Scientific Reports.
A microscopic fungus called Candida tropicalis triggered gut inflammation and exacerbated symptoms of Crohn's disease, in a recent study conducted at Case Western Reserve University School of Medicine.
A team of scientists from the VIB lab of Han Remaut and the lab of Yves Dufrêne at UCL Louvain-La-Neuve collaborated on a study of functional amyloids -protein aggregates with the typical amyloid structure that do not lead to disease but rather serve a dedicated biological function.
Antibiotics were the wonder drug of the 20th century, but persistent use and over-prescription have opened the door that has allowed bacteria to evolve resistance.
Urinary tract infections (UTIs) are among the most common infections, and they tend to come back again and again, even when treated. Most UTIs are caused by E. coli that live in the gut and spread to the urinary tract.
By tagging a cell's proteins with fluorescent beacons, Cornell researchers have found out how E. coli bacteria defend themselves against antibiotics and other poisons. Probably not good news for the bacteria.
Imagine wearing a device that continuously analyzes your sweat or blood for different types of biomarkers, such as proteins that show you may have breast cancer or lung cancer.
Studying the food poisoning bacteria E. coli may have led scientists to discover a new and improved tool to detect cancer.
Researchers at the Novo Nordisk Foundation Center for Biosustainability in Denmark have developed a method of producing P450 enzymes - used by plants to defend against predators and microbes - in bacterial cell factories. The process could facilitate the production of large quantities of the enzymes, which are also involved in the biosynthesis of active ingredients of cancer drugs.
