Figure

Genetic environments associated with the mcr-1 (mobile colistin resistance 1) gene detected in select Enterobacteriacae isolates from pigs, Portugal, by PCR. I) 1 copy of ISApl1 associated with mcr-1 in 5′ region; II) 2 copies of ISApl1 in 5′ and 3′ regions of mcr-1; III) no copy of ISApl1 associated with mcr-1; IV) truncated copy of ISApl1 associated with mcr-1 in 5′ region inserted in a kinase gene. IS, insertion sequence; orf, open reading frame.
