An enzyme that keeps intestinal bacteria out of the bloodstream may also play an important role in maintaining the normal microbial population of the gastrointestinal system. Since the loss of beneficial bacteria that usually results from antibiotic therapy can sometimes lead to serious health p... Read More
For decades, factory farms have used antibiotics even in healthy animals to promote faster growth and prevent disease that could sicken livestock held in confined quarters.
The benefit: cheaper, more plentiful meat for consumers.
But a firestorm has erupted over a federal proposal recommen... Read More
Scientists have traced a bone infection to a newly described species of bacteria related to the tuberculosis pathogen. The discovery may help improve diagnosis and treatment of similar infections, according to a study.
Some rare genetic diseases can make patients susceptible to infections wit... Read More
A new approach that uses machine learning to detect harmful bacteria in food will allow for better identification of known—and unknown—classes of food pathogens.
“The sheer number of existing bacterial pathogens and their high mutation rate makes it extremely difficult to automate their detec... Read More
Scientists have identified the eight human papillomavirus (HPV) types responsible for more than 90 percent of cervical cancer cases worldwide and say they should be the targets for the next generation of vaccines.
Drugmakers GlaxoSmithKline and Merck & Co. already make vaccines against HPV st... Read More
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have discovered a key difference in the way human cells and Mycobacterium tuberculosis bacteria, which cause TB, deliver unwanted proteins — marked with a "kiss of death" sequence — to t...

In only the second elimination of a disease in history, rinderpest — a virus that used to kill cattle by the millions, leading to famine and death among humans — has been declared wiped off the face of the earth.
Rinderpest, which means “cattle plague” in German, does not infect humans, thou... Read More
E.coli is one of most well-known infections. But in a growing number of cases, this common stomach bug is turning into a superbug. Tonight, CBS Evening News Anchor Katie Couric reports on a deadly version of E.coli - with a genetic mutation that makes it extremely hard to treat.
Tom Dukes nev... Read More
Scientists are hailing a breakthrough that could lead to one of medicine's holy grails - a cure for the common cold.
Researchers have found they can attach tiny studs of silver to the surface of harmless bacteria, giving them the ability to destroy viruses.
They have tested the silver-impr... Read More
New Evidence of Common Gastric Infection as Invasive Pathogen May Explain Antibiotic Resistance
Helicobacter pylori, the bacterium largely associated with gastritis and peptic ulcers in humans, may invade and replicate in gastric epithelial cells say researchers from China. This discovery dis... Read More
In the western Caribbean, some coral reefs have turned into eerie white ghost towns.
Scientists with the Smithsonian Tropical Research Institute have documented a major bleaching event in the reefs near Panama and the island of Curaçao. Such bleaching occurs when a reef loses the tiny photosy... Read More
In only the second elimination of a disease in history, rinderpest — a virus that used to kill cattle and wildlife by the millions — has been declared wiped off the face of the earth.
Rinderpest, which means “cattle plague” in German, does not affect humans, though it belongs to the same viru... Read More
Could giving infants antibiotics in their first year of life trigger asthma and allergies that develop later on in childhood?
That's the suspicion of a team of Canadian medical researchers who are conducting a $2.5 million study to find the answer.
More than 50 percent of Canadian infants ... Read More
Chiquita Brands International said Friday that it is using a new wash on its bagged salads that better kills bacteria including E. coli and salmonella.
Chiquita (CQB) said it will longer use the industry standard wash of chlorine, which it said leaves some bacteria on the leaves. Instead it w... Read More
Technologies for rapid detection of bacterial pathogens are crucial to maintaining a secure food supply.
Researchers from the School of Science at Indiana University-Purdue University Indianapolis (IUPUI) and the Bindley Bioscience Center at Purdue University have developed a novel approach t... Read More
Did you know that our bodies are home to trillions — yes, trillions — of microorganisms that play a role both in keeping us healthy and making us sick?
Taken together, these teeming communities of bacteria, viruses and fungi make up what's known as our microbiome, and probing its secrets has ... Read More
Personal touch-screen devices – iPads, BlackBerrys and Droids – are now seemingly everywhere, potentially harboring the germs and viruses that turn voices raspy and send noses running.

New research shows, how like a conjuring trick with interlocking rings, two interlocked pieces of DNA are separated after DNA is copied or repaired.
While reconstituting the DNA repair system of yeast in a test tube, scientists found that a complex of proteins called Sgs1, Top3, and Rmi1 allo... Read More
