Identification of antimicrobial resistance genes and drug resistance analysis of Escherichia coli in the animal farm environment

Overall, the detection rate of AMR genes in feces and soil from hog farms was high, and the isolated strains of E. coli from both feces and soil showed multi-drug resistance. Also, the results showed that the AMR genes and drug resistance in the feces and soil from the hog farms are similar. These findings suggested that the AMR genes could be transmitted horizontally from the animal feces to surrounding environments of farms. Therefore, it is urgent need to strengthen the monitoring and guide the rational use of antimicrobial drugs in the hog industry of Zhanjiang, China.
