A major review recently published in Frontiers of Microbiology examines the broader issues associated with widespread antibiotic resistance. The paper, by Professor Michael Gillings from Macquarie University, discussed the increasing concentration of antibiotics in densely populated areas. He says that the effects of antibiotics and resistance genes have now spread to locations distant from the influence of developed societies, such as the Artic, Antarctica, and the Amazonian jungle. http://medicalxpress.com/news/2013-02-consequences-overuse-antibiotics-amazon.html Medical research Tue, 19 Feb 2013 11:20:01 EST news280489325 The increasing production and use of antibiotics, about half of which is used in animal production, is mirrored by the growing number of antibiotic resistance genes, or ARGs, effectively reducing antibiotics' ability to fend off diseases – in animals and humans. http://medicalxpress.com/news/2013-02-unchecked-antibiotic-animals-affect-global.html Medical research Mon, 11 Feb 2013 15:00:14 EST news279804999 The bacterium Streptococcus pneumoniae – which can cause pneumonia, meningitis, bacteremia and sepsis – likes to share its antibiotic-defeating weaponry with its neighbors. Individual cells can pass resistance genes to one another through a process called horizontal gene transfer, or by "transformation," the uptake of DNA from the environment. http://medicalxpress.com/news/2012-10-scientists-bacterial-resistance-genes.html Medical research Wed, 24 Oct 2012 14:03:51 EST news270306204 Shahriar Mobashery, a University of Notre Dame researcher, is one of the coauthors of a new paper by a group of the world's leading scientists in academia and industry that calls for strong steps to be taken to control the global crisis of antibiotic resistance in bacteria. The group issued a priority list of steps that need to be taken on a global scale to resolve the crisis. http://medicalxpress.com/news/2011-12-paper-strong-tackle-antibiotic-resistance.html Medications Thu, 08 Dec 2011 15:41:43 EST news242581293 Waters polluted by the ordure of pigs, poultry, or cattle represent a reservoir of antibiotic resistance genes, both known and potentially novel. These resistance genes can be spread among different bacterial species by bacteriophage, bacteria-infecting viruses, according to a paper in the October Antimicrobial Agents and Chemotherapy. http://medicalxpress.com/news/2011-10-newly-reservoir-antibiotic-resistance-genes.html Medical research Fri, 21 Oct 2011 10:09:22 EST news238410548 Professor Bill Keevil, Head of the Microbiology Group and Director of the Environmental Healthcare Unit at the University of Southampton, has presented research into the mechanism by which copper exerts its antimicrobial effect on antibiotic-resistant organisms at the World Health Organization's first International Conference on Prevention and Infection Control (ICPIC). http://medicalxpress.com/news/2011-07-copper-infection-percent.html Diseases, Conditions, Syndromes Fri, 01 Jul 2011 10:39:08 EST news228735533 (PhysOrg.com) -- The discovery of two genes that encode copper- and sulfur-binding repressors in the hospital terror Staphylococcus aureus means two new potential avenues for controlling the increasingly drug-resistant bacterium, scientists say in the April 15, 2011 issue of the Journal of Biological Chemistry. http://medicalxpress.com/news/2011-04-discovery-genes-stemming-staph-infections.html Medical research Tue, 12 Apr 2011 09:35:34 EST news221819711
