Exposure to cigarette smoke has long been associated with increased frequency of respiratory infections—which are harder to treat in smoke-exposed people than in those who lack such exposures. Now Ritwij Kulkarni of Columbia University, New York, NY, and colleagues show that cigarette smoke actually boosts virulence of Staphylococcus aureus bacteria. Their study appears in the November 2012 issue of the journal Infection and Immunity. http://medicalxpress.com/news/2012-11-cigarette-boosts-virulence-staphylococcus-aureus.html Diseases, Conditions, Syndromes Thu, 08 Nov 2012 15:45:02 EST news271611884 Scientists at Queen's University Belfast have developed a new technique which has the potential to kill off hospital superbugs like Pseudomonas aeruginosa, C. difficile and MRSA. http://medicalxpress.com/news/2012-10-plasma-jet-cold-shoulder-superbugs.html Medical research Wed, 03 Oct 2012 09:40:55 EST news268476045 There's new hope for development of an antibiotic that can put down a lethal bacteria or superbug linked to the deaths of hundreds of hospital patients around the world. http://medicalxpress.com/news/2012-06-weakness-armor-killer-hospital-bacteria.html Diseases, Conditions, Syndromes Thu, 07 Jun 2012 17:00:14 EST news258306056 (Medical Xpress) -- Researchers at the University of Liverpool are examining the evolution of Pseudomonas aeruginosa over time in the lungs of ten people with cystic fibrosis to understand why it persists in these patients and why its response to antibiotics is so varied. http://medicalxpress.com/news/2012-03-parallel-evolution-cystic-fibrosis.html Medical research Tue, 06 Mar 2012 06:30:02 EST news250237072 According to the World Health Organization (WHO), one-third of the world's population is currently infected with tuberculosis bacteria. The bacteria is incredibly resistant to treatment, and despite its prevalence, very little is known about why it is so stress tolerant. But, researchers at the University of Pittsburgh have been developing a new way of culturing tuberculosis bacteria, which could lead to new insights and treatments. http://medicalxpress.com/news/2012-02-tuberculosis-technology-published.html Diseases, Conditions, Syndromes Wed, 15 Feb 2012 08:50:13 EST news248518208
