It is alarming that the plasmid-mediated mcr-1-encoded colistin resistance discovered by Yi-Yun Liu and colleagues,1 probably selected in cows and pigs as discussed by Marisa Haenni and colleagues2 and Surbhi Malhorta-Kumar and colleagues,3 is now spreading globally in Gram-negative pathogens.4 Moreover, colistin-resistant Escherichia coli without the canonical mcr-1 gene suggest that other (transferable) colistin-resistant mechanisms exist.3
