Staph Aureus Rates Of Resistance To Certain Antibiotics Show A Decrease Over Time

Posted 14 Jun 2017 by Drugs.com

TUESDAY, June 13, 2017 – Staphylococcus aureus infections among U.S. hospital patients have been less resistant to key antibiotics in recent years, a new study finds. Between 2009 and 2015, researchers tested antibiotic resistance in more than 19,000 S. aureus samples from 42 medical centers nationwide. "Results showed that S. aureus' rates of resistance to certain antibiotics decreased over time, which isn't often seen," study co-author Dr. Helio Sader said in an American Society for Microbiology news release. Sader is senior director of microbiology and surveillance at JMI Laboratories in North Liberty, Iowa. Rates of S. aureus resistance to the antibiotic oxacillin (Bactocill) fell from 47.2 percent in 2009 to 43.6 percent in 2015 to 42.2 percent in 2016. S. aureus resistance to other antibiotics, such as levofloxacin (Levaquin), clindamycin (Cleocin) and erythromycin, also ... Read more

There's Bad Buzz on Antibiotics for Honeybees

Posted 14 Mar 2017 by Drugs.com

TUESDAY, March 14, 2017 – Antibiotics can increase a honeybee's risk of death, a discovery that also has implications for people, researchers say. In a laboratory experiment, the University of Texas at Austin team gave some honeybees a syrup with the common antibiotic tetracycline and gave other honeybees a syrup without antibiotics. The bees that received the antibiotic were marked with a dot and were half as likely to survive for a week compared to those that did not receive the antibiotic. The researchers also found that the antibiotic cleared out beneficial gut bacteria in the bees, enabling a harmful type of bacteria called Serratia – which also occurs in people – to become established. The results indicate that antibiotics given to honeybees to protect them could be one reason for sudden declines in honeybee colonies, along with pesticides and habitat loss. In large-scale U.S. ...
