Oxazolidinones, including linezolid and tedizolid, are effective antimicrobial agents for treating infections caused by MDR Gram-positive bacteria, including VRE.1,2Linezolid is the first commercially available oxazolidinone that can inhibit protein synthesis by binding to the peptidyltransferase centre of the bacterial 23S rRNA. After introduction of linezolid, the resistance mechanism that emerged rapidly was related to mutations in genes coding for the 23S rRNA. The transferable oxazolidinone resistance determinants, cfr and optrA, have been reported in enterococci in several regions worldwide.3–6 Very recently, another transferable oxazolidinone resistance gene, poxtA, was reported in an MRSA of clinical origin…

I am an Italian blogger, active since 2005 with main focus on emerging infectious diseases such as avian influenza, SARS, antibiotics resistance, and many other global Health issues. Other fields of interest are: climate change, global warming, geological and biological sciences. My activity consists mainly in collection and analysis of news, public services updates, confronting sources and making decision about what are the 'signals' of an impending crisis (an outbreak, for example). When a signal is detected, I follow traces during the entire course of an event. I started in 2005 my blog ''A TIME'S MEMORY'', now with more than 40,000 posts and 3 millions of web interactions. Subsequently I added an Italian Language blog, then discontinued because of very low traffic and interest. I contributed for seven years to a public forum ( in the midst of the Ebola epidemic in West Africa in 2014, I left the site to continue alone my data tracking job.
