Zinc Helps against Infection by Tapping Brakes in Immune Response

COLUMBUS, Ohio – New research suggests that zinc helps control infections by gently tapping the brakes on the immune response in a way that prevents out-of-control inflammation that can be damaging and even deadly.

Scientists determined in human cell culture and animal studies that a protein lures zinc into key cells that are first-responders against infection. The zinc then interacts with a process that is vital to the fight against infection and by doing so helps balance the immune response. (more…)

Will This Be The End of Hamburger Disease?

Hamburger disease, a debilitating form of food poisoning, may be a thing of the past. New findings from an international research collaboration conducted by the French National Institute for Agronomic Research (INRA), involving the Université de Montréal are the first to show how the contaminating E.coli bacterium is able to survive in the competitive environment of a cow’s intestine by scavenging specific food sources. Published in this month’s Environmental Microbiology, and featured in Nature Reviews Microbiology, this study may lead to non-medicinal methods for eradicating this invasive bug. 

“We studied E.coli O157:H7, which is the most prevalent species of bacteria associated with larger outbreaks,” says Josée Harel, co-author of the study and director of the Groupe de Recherche sur les Maladies Infectieuses du Porc at the Université de Montréal’s Faculty of Veterinary Medicine. “These outbreaks have been associated with direct contact with the farm environment and with the consumption of meat, raw milk and dairy products. Reduction or eradication of O157:H7 in cows will lead to a substantial decrease in food contamination and consequential human infections.”  (more…)

UN Predicts Global Rise of Food Prices

In the next ten years, prices for agricultural products in the world will grow in real terms by 15-40%, say experts from the Organization for Economic Cooperation and Development and the Food and Agriculture Organization of the UN. The reason for it is the increasing demand for food in developing countries and production of biofuels.
