The BBC reports [bbc.co.uk] that the world is on the cusp of a 'post-antibiotic era'. A new mutation of bacteria in China has something "dubbed the MCR-1 gene", that prevented colistin - the antibiotic of last resort - from killing bacteria.
Resistance to colistin has emerged before. However, the crucial difference this time is the mutation has arisen in a way that is very easily shared between bacteria
There's plenty to blame - pumping livestock full of them for "preventative measures", doctors prescribing them for colds and flus, and people not finishing a course when they are prescribed them - but the future currently looks bleak.
