Plasmid localisation of atrazine-degrading genes in newly described Chelatobacter and Arthrobacter strains.

abstract：:Improving our understanding of antibiotic resistance in soils is important for the protection of human, animal and ecological health. In south-central Idaho, antibiotic resistance genes (ARGs) [blaCTX-M-1, erm(B), sul1, tet(B), tet(M) and tet(X)] and a class 1 integron-integrase gene (intI1) were quantified in agricul...
