New method less prone to contamination, provides further insight into immune response A 500-year-old frozen Incan mummy suffered from a bacterial lung infection at the time of its death, as revealed by a novel proteomics method that shows evidence of an active pathogenic infection in an ancient sample for the first time. The full report is published July 25 in the open access journal PLoS ONE. Detecting diseases in ancient remains is often fraught with difficulty, especially because of...

In an effort to save the dwindling honeybee population researchers at the University of Nevada, Las Vegas are looking to viruses to help treat one of the most destructive and widespread bee brood diseases in the United States. They report their findings today at the 2012 General Meeting of the American Society for Microbiology. "Our food supply depends on the actions of millions of insects such as the common honeybee. Due to the importance of honeybees a pollinators in the agriculture of...

An international team of scientists, funded in the UK by the Biotechnology and Biological Sciences Research Council (BBSRC), has uncovered the structure of the protective protein coat which surrounds many bacteria like a miniature suit of armor. Their research, which is published today (Sunday 10 June) in Nature, has far ranging consequences in helping us understand how some pathogenic bacteria infect humans and animals, and could help us develop new vaccines. Until now, scientists have...

University of Alberta researchers found a chink in the molecular armor of the pathogen Acinetobacter baumannii There's new hope for development of an antibiotic that can put down a lethal bacteria or superbug linked to the deaths of hundreds of hospital patients around the world. Researchers from the University of Alberta-based Alberta Glycomics Centre found a chink in the molecular armour of the pathogen Acinetobacter baumannii. The bacteria first appeared in the 1970's and in the last...

Max Planck scientists decipher the structure of bacterial injection needles at atomic resolution The plague, bacterial dysentery, and cholera have one thing in common: These dangerous diseases are caused by bacteria which infect their host using a sophisticated injection apparatus. Through needle-like structures, they release molecular agents into their host cell, thereby evading the immune response. Researchers at the Max Planck Institute for Biophysical Chemistry in...

Garlic Fights Food-Borne Illness Better Than Antibiotics

Discovery could play role in treatments for food and prep areas Researchers at Washington State University have found that a compound in garlic is 100 times more effective than two popular antibiotics at fighting the Campylobacter bacterium, one of the most common causes of intestinal illness. Their work was recently published in the Journal of Antimicrobial Chemotherapy. The discovery opens the door to new treatments for raw and processed meats and food preparation surfaces. "This...

A vaccine could be developed to prevent Campylobacter being carried in chickens. This approach could drastically cut the number of cases of food poisoning, saving the UK economy millions each year, says an American scientist presenting his work at the Society for General Microbiology's Spring Conference in Dublin. Food-borne illness costs the UK an estimated £2 billion each year. Campylobacter is the leading cause of food-borne illness and is responsible for about 30% of cases in the...

Findings point to new approaches to fighting powerful gut infections UC Irvine researchers have discovered how salmonella, a bacterium found in contaminated raw foods that causes major gastrointestinal distress in humans, thrives in the digestive tract despite the immune system´s best efforts to destroy it. Their findings help explain why salmonella is difficult to eradicate and point to new approaches for possible treatments. Most people infected with salmonella suffer from...
