QUIROG, Cecilia; NASTRO, Marcela  and  DI CONZA, José. Current scenario of plasmid-mediated colistin resistance in Latin America. Rev. argent. microbiol. [online]. 2019, vol.51, n.1, pp.93-100. ISSN 0325-7541.

Colistin resistance can occur by chromosomal mutations and by acquisition of plasmid-carrying determinants, mainly mcr-1. In the recent years, we have observed the out-burst of this resistance gene in our region. Due to the risk of the rapid dissemination of mcr-1, this finding has worried and alerted different actors from the health field and has become one of the most prolific topics. Our review compiles available reports of well-documented mcr-1-positive strains of Enterobacteriaceae, obtained from different samples in Argentina and other countries of Latin America. Furthermore, it addresses the association of mcr-1 with ESBL resistance markers and outlines the platforms involved in their dissemination.

Keywords : mcr-1; Colistin resistance; Enterobacteriaceae; Latin America.
