Scientists at the University of York have discovered how certain bacteria such as Escherichia coli have evolved to capture rare sugars from their environment giving them an evolutionary advantage in naturally competitive environments like the human gut. http://www.physorg.com/news177244138.html Chemistry Thu, 12 Nov 2009 10:31:40 EST news177244138 Immunology researchers at UT Southwestern Medical Center have found that bacteria present in the human gut help initiate the body's defense mechanisms against Toxoplasma gondii, the parasite responsible for toxoplasmosis. http://www.physorg.com/news169909790.html Biology Wed, 19 Aug 2009 15:00:10 EST news169909790 Salmonella, what's gotten into you? Researchers have been asking themselves this question ever since Salmonella bacteria grown on board the space shuttle returned to Earth 3 to 7 times more virulent than Salmonella grown on the ground under otherwise identical conditions. Figuring out why could help safeguard astronauts from disease and lead to new treatments for food poisoning and other common ailments on Earth. http://www.physorg.com/news160931238.html Biology Thu, 07 May 2009 16:07:58 EST news160931238 The detailed structure of a protective 'jacket' that surrounds cells of the Clostridium difficile superbug, and which helps the dangerous pathogen stick to human host cells and tissues, is revealed in part in the 1 March issue of Molecular Microbiology. http://www.physorg.com/news154960637.html Biology Fri, 27 Feb 2009 12:38:08 EST news154960637 (PhysOrg.com) -- Bacteria naturally present in the human gut could produce substances that help to protect against colon cancer and provide therapy for inflammatory bowel disease. http://www.physorg.com/news153145784.html Biology Fri, 06 Feb 2009 12:30:09 EST news153145784 In terms of diversity and sheer numbers, the microbes occupying the human gut easily dwarf the billions of people inhabiting the Earth. Numbering in the tens of trillions and representing many thousands of distinct genetic families, this microbiome, as it's called, helps the body perform a variety of regulatory and digestive functions, many still poorly understood. http://www.physorg.com/news151608095.html Biology Mon, 19 Jan 2009 17:22:20 EST news151608095 We are always being told by marketers of healthy yogurts that the human gut contains a bustling community of different bacteria, both good and bad, and that this balance is vital to keeping you healthy. But if you target the disease-causing bacteria with medicine, what might be the collateral damage to their health-associated cousins that call the human body home? http://www.physorg.com/news146220165.html Biology Tue, 18 Nov 2008 08:42:45 EST news146220165
