Until recently, the term 'extensive drug resistance' (XDR) was held to be applicable to Mycobacterium tuberculosis only. It is now clear that Gram-negative bacilli are moving a step closer towards acquiring similar resistance. The emergence of multi- (MDR) and pan-drug resistant (PDR) Gram-negative health care-associated pathogens has been confined to non-fermenters such as Pseudomonas aeruginosa and Acinetobacter baumannii.
