Scientists are building a clearer image of the machinery employed by bacteria to spread antibiotic resistance or cause diseases such as whooping cough, peptic stomach ulcers and legionnaires' disease. http://www.physorg.com/news178810154.html Biology Mon, 30 Nov 2009 13:29:45 EST news178810154 The American chestnut was a dominant species in eastern U.S.'s forests before a blight wiped it out in the early 1900s. Today it's being returned to the landscape thanks in part to work by a University of Tennessee Forestry alumna and the UT Tree Improvement Program (UT TIP). http://www.physorg.com/news172931946.html Biology Wed, 23 Sep 2009 14:10:02 EST news172931946 Scientists studying Staphylococcus bacteria, including methicillin-resistant S. aureus (MRSA), have discovered a potent staph toxin responsible for disease severity. They also found the gene for the toxin traveling with a genetic component of Staphylococcus that controls resistance to antibiotics. The study, now online in PLoS Pathogens, shows for the first time that genetic factors that affect Staphylococcus virulence and drug resistance can be transferred from one strain to another in one exchange event. http://www.physorg.com/news168266826.html Medicine & Health Fri, 31 Jul 2009 13:48:19 EST news168266826 Scientists have identified the structure of a key component of the bacteria behind such diseases as whooping cough, peptic stomach ulcers and Legionnaires' disease. The research, funded by the Wellcome Trust and the Biotechnology and Biological Sciences Research Council (BBSRC), sheds light on how antibiotic resistance genes spread from one bacterium to another. The research may help scientists develop novel treatments for these diseases and novel ways to curtail the spread of antibiotic resistance. http://www.physorg.com/news150646319.html Medicine & Health Thu, 08 Jan 2009 14:11:59 EST news150646319 (PhysOrg.com) -- University of Adelaide researchers have identified new sources of stem and leaf rust resistance in wild grass relatives of wheat sourced mostly from the 'fertile crescent' of the Middle East. http://www.physorg.com/news143817302.html Biology Tue, 21 Oct 2008 14:15:02 EST news143817302
