New study reveals how human astroviruses bind to humans cells and paves the way for new therapies and vaccines Human astroviruses are a leading viral cause of the stomach bug—think vomiting, diarrhea, and fever. It often impacts young children and older adults, leading to vicious cycles of sickness and malnutrition, particularly for those in low and middle income countries. It’s very commonly found in wastewater studies, meaning it’s frequently circulating in communities. As of now, there are no vaccines for…
A new target for nitric oxide has been revealed in studies of how it inhibits the growth of Salmonella. This bacterium is a common cause of food-poisoning. “Nitric oxide is naturally produced in the nose and the gut and other tissues in the body to ward off infection,” explained the senior author of the paper, Dr. Ferric Fang. He is a University of Washington (UW) professor of laboratory medicine, microbiology and medicine. …
