This study evaluated the effects of medicinal preparations containing colistin sulphate on the incidence of the plasmid mcr-1 gene in nonpathogenic strains of E. coli in the intestinal flora of healthy broiler chickens intended for slaughter.

The samples came from flocks treated with colistin sulphate (n = 87) or not treated (n = 71). A total of 108 samples were collected in the first slaughterhouse (each sample was swabbed from five chickens chosen at random, from 70 treated and 38 not treated flocks), and 50 samples were taken in the second slaughterhouse (also in this instance each sample was swabbed from five chickens chosen at random, from 17 treated and 33 not treated flocks)
