Old drug, new findings: colistin resistance and dependence of

Colistin is an old drug, and its use has recently resurged because of increasing antibiotic resistance in gram-negative bacteria such as Acinetobacter baumannii. Although the colistin resistance rates in gram-negative bacteria are currently not high, many colistin-resistant isolates are being identified and the possibility of horizontal transmission of colistin resistance has increased because of the plasmid-borne colistin resistance gene mcr-1 (mobilized colistin resistance). In this review, we have discussed colistin resistance in A. baumannii. In addition, we have reviewed an abnormal phenomenon called colistin dependence in A. baumannii.
