Primera comunicación en Chile de la detección del gen mcr-1 en un aislado clínico de Escherichia coli resistente a colistín / First report in Chile of a clinical isolate of Escherichia coli resistant to colistin harbouring the mcr-1 gene

ABSTRACT

Recently it was described the plasmidial gene mcr-1 associated with colistin resistance. We screened by PCR and sequencing for gene mcr-1 in thirteen clinical isolates resistant to colistin. We observed amplification in one E. coli. To our knowledge, this is the first report of the presence of mcr-1 gene in Chile.
