A total of 108 meropenem-resistant Enterobacteriaceae isolates were obtained from 1658 rectal swabs collected from 15 unrelated commercial chicken farms in China between 2014 and 2016. These samples yielded sixteen Escherichia coli and two Klebsiella pneumoniae isolates of diverse sequence types carrying a blaNDM-5-bearing IncX3 plasmid. Klebsiella pneumoniae strain sequence type 709 (ST709) has two blaNDM-5-carrying plasmids that were transferred together to E.coli.

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.
