Characterization of mcr-5 -Harboring Salmonella enterica subsp. enterica Serovar Typhimurium Isolates from Animal and Food Origin in Germany

We characterized eight -positive subsp. serovar Typhimurium sequence type 34 (ST34) isolates obtained from pigs and meat in Germany. Five plasmid types were identified harboring on Tn or putative mobile insertion cassettes. The mobility of was confirmed by integration of Tn into the bacterial chromo...

Summary:We characterized eight -positive subsp. serovar Typhimurium sequence type 34 (ST34) isolates obtained from pigs and meat in Germany. Five plasmid types were identified harboring on Tn or putative mobile insertion cassettes. The mobility of was confirmed by integration of Tn into the bacterial chromosomes of two strains and the detection of conjugative plasmids. The association with mobile genetic elements might further enhance distribution.
