Bacteria of the genus Salmonella cause most food-borne illnesses. The bacteria attach to cells of the intestinal wall and induce their own ingestion by cells of the intestinal epithelium. Up till now, researchers assumed that Salmonella have to induce the formation of distinctive membrane waves in order to invade these gut cells. Researchers from the Helmholtz Centre for Infection Research in Braunschweig, Germany, now refuted this common doctrine. http://www.physorg.com/news180265995.html Biology Thu, 17 Dec 2009 10:10:09 EST news180265995 With disease outbreaks linked to unpasteurized milk rising in the United States, a review published in the January 1, 2009 issue of Clinical Infectious Diseases examines the dangers of drinking raw milk. http://www.physorg.com/news148662665.html Medicine & Health Tue, 16 Dec 2008 15:11:05 EST news148662665 Raw milk is illegal in many countries as it can be contaminated with potentially harmful microbes. Contamination can also spoil the milk, making it taste bitter and turn thick and sticky. Now scientists have discovered new species of bacteria that can grow at low temperatures, spoiling raw milk even when it is refrigerated. According to research published in the November issue of the International Journal of Systematic and Evolutionary Microbiology, the microbial population of raw milk is much more complex than previously thought. http://www.physorg.com/news146114826.html Biology Mon, 17 Nov 2008 03:27:06 EST news146114826
