Dear All: There’s a very comprehensive review of the polymyxins by Poirel, Jayol, and Nordmann just out in Clin Micro Reviews (https://journals.asm.org/doi/10.1128/CMR.00064-16). If you’re a fan of good quality graphics as way to tell the story of AMR, their Figure 4 is worth capturing! Ditto their Figure 5 of outbreaks of colistin-resistant, carbapenemase-producing K. pneumoniae.
