- Detection of plasmid mediated colistin resistance (MCR-1) in Escherichia coli and Salmonella enterica isolated from poultry and swine in SpainPublication . Quesada, Alberto; Ugarte-Ruiz, María; Iglesias, M. Rocío; Porrero, M. Concepción; Martínez, Remigio; Florez-Cuadrado, Diego; Campos, Maria J.; García, María; Píriz, Segundo; Sáez, José Luis; Domínguez, LucasRecent findings suggest that use of colistin as a last resort antibiotic is seriously threatened by the rise of a new plasmid mediated mechanism of resistance (MCR-1). This work identifies, for the first time in Southern Europe, the gene mcr-1 in nine strains from farm animals (poultry and swine) corresponding to five Escherichia coli and four Salmonella enterica, amongwhich three belong to serovar Typhimuriumand one to Rissen. TheMCR-1 was found encoded by a plasmid highly mobilizable by conjugation to the E. coli J53 strain. Two E. coli strains carried two determinants, mcr-1 plus pmrA or pmrB mutations, known to confer colistin resistance.
