Abstract

Colistin and polymyxin B are the “last reserve” antimicrobials for the treatment of extensively drug-resistant Gram-negative bacterial infections. The rapidly increasing prevalence of polymyxin resistance mediated by the mcr gene localized on plasmid DNA currently poses a high epidemiological threat. In order to control a distribution of mcr genes, it is necessary to develop highly accurate, highly sensitive and easy-to-use diagnostic tools. This paper provides a review of the most relevant studies on the molecular epidemiology as well as current approaches to microbiological and molecular detection of mcr group genes.
