Multidrug-resistant pathogens are becoming more frequent, and the few "last resort" treatments available for infections with these bacteria have also shown an increase in use in recent years, according to a study published May 16 in the open access journal PLoS ONE. http://medicalxpress.com/news/2012-05-resort-antibiotics-increasingly-multidrug-resistant-bugs.html Medications Wed, 16 May 2012 17:00:15 EST news256405963 Proteins belonging to the large and important family of ABC transporters have been associated with metabolic diseases and can cause resistance to antibiotics. Biochemists from the University of Zurich and the NCCR Structural Biology have succeeded in determining the atomic structure of a new ABC transporter. The insights gained could give rise to new therapies to treat multi-resistant bacteria, cystic fibrosis or gout, for instance. http://medicalxpress.com/news/2012-03-hot-trail-metabolic-diseases-resistance.html Medical research Wed, 28 Mar 2012 10:06:56 EST news252148005 Combining common antibiotics with additional compounds could make previously resistant bacteria more susceptible to the same antibiotics. 'Resuscitation' of existing antibiotics has the potential to make infections caused by multidrug-resistant bacteria easier to control, reducing antibiotic usage and levels of antimicrobial resistance, say scientists presenting their work at the Society for General Microbiology's Spring Conference in Dublin this week. http://medicalxpress.com/news/2012-03-resuscitating-antibiotics-drug-resistance.html Medications Wed, 28 Mar 2012 03:25:40 EST news252123929 Aggressive infections in hospitals are an increasing health problem worldwide.

A new study, led by Dr. Amy R. Sapkota of the University of Maryland School of Public Health, provides data demonstrating that poultry farms that have transitioned from conventional to organic practices and ceased using antibiotics have significantly lower levels of drug-resistant enterococci bacteria. http://medicalxpress.com/news/2011-08-poultry-farms-significantly-antibiotic-resistant-bacteria.html Medical research Wed, 10 Aug 2011 03:00:03 EST news232163505 New research conducted at Uppsala University shows that extremely low concentrations of antibiotics can enrich for antibiotic resistant bacteria.
