Scientists from the Uniformed Services University of the Health Sciences (USU) have discovered that diets high in salt may increase the virulence of the pathogen Helicobacter pylori (H. pylori), which is the most common cause of ulcers in the stomach and duodenum.
University of Nottingham experts have joined forces with Canadian biotech company GangaGen Life Sciences Inc to develop new weapons in the fight against food poisoning.
Could the food we eat be contributing to the continuing rise of antibiotic-resistant infections? Harmless and even beneficial bacteria that exist in our food supply may also be carrying genes that code for antibiotic resistance. Once in our bodies, could they transmit the resistance genes to disease-causing bacteria?
Scientists have identified yet another risk from a high-salt diet. High concentrations of salt in the stomach appear to induce gene activity in the ulcer-causing bacterium Helicobacter pylori, making it more virulent and increasing the likelihood of an infected person developing a severe gastric disease.
Men with chronic gum disease may have an increased risk of tongue cancer, regardless of whether they smoke, according to a report in the May issue of Archives of Otolaryngology-Head & Neck Surgery, one of the JAMA/Archives journals.
Researchers at the University of Minnesota and the University of Illinois at Urbana-Champaign have developed a new therapeutic that neutralizes Toxic Shock Syndrome (TSS) more effectively than other treatments.
The biotechnology company Alimentary Health today announced results from two studies that demonstrate the anti-inflammatory activity of a natural probiotic bacterial strain of human origin, Bifantis? (Bifidobacterium infantis 35624), in models of arthritis and Salmonella infection.
Now that the genome sequences of hundreds of bacteria and viruses are known, we can design tests that will rapidly detect the presence of these species based solely on their DNA.
When it comes to growing cells in a lab, technique matters. A new Brown University study shows that nerve cells grown in three-dimensional cultures use 1,766 genes differently compared to nerve cells grown in standard two-dimensional petri dishes.
Circles, slaloms, figure eights, and loop-the-loops ? biologists studying the motion of Listeria monocytogenes sensed that these paths were related, but they didn?t have a good way to define what fit in and what didn?t. A remarkably simple new mathematical description, published online in the Proceedings of the National Academy of Sciences [Abstract], reproduces all these shapes with just one pair of equations and only two key variables.
