Resistance to Colistin

In china there was a recent discovery of e coli which had a resistance to colistin a antibiotic normally only used in cases where other antibiotics do not work for gram negative bacteria. Here are two more reliable article sources if needed for further interest. http://www.statnews.com/2015/11/18/superbugs-china-colistin/ http://www.thelancet.com/pdfs/journals/laninf/PIIS1473-3099(15)00424-7.pdf As it has been spotted out in earlier articles though this is not the first time colistin resistance has been shown. The alarming matter is via the usage of plasmids it can spread to other bacteria giving those the same resistances.
