Analysis of the location of mcr-1/blaNDM among transconjugants and their donors. (A) S1 nuclease-PFGE of transconjugants and their donors carrying blaNDM. (B) Southern blot hybridization with the blaNDM probe. (C) S1 nuclease-PFGE of transconjugants and their donors carrying mcr-1. (D) Southern blot hybridization with the mcr-1 probe. Lane M: chromosomal DNA of Salmonella enterica serotype Braenderup H9812 digested with XbaI serving as size markers. The red arrows indicate bigger bands, which are portion of the mcr-1/blaNDM-5/9-carrying plasmids not exposed to S1 nuclease in the S1-PFGE experiment.
