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 agricultural and non-agricultural soils (96 total sites) under various land use practices (cropland, forestland, inactive cropland, pastureland, rangeland, recreational, residential). We hypothesized that gene occurrence and abundance would be greater in intensively managed agricultural soils. The ARGs (except blaCTX-M-1) and intI1 gene were detected in many of the soils (15 to 58 out of 96 samples), with sul1 and intI1 being detected the most frequently (60% of samples). All of the genes were detected more frequently in the cropland soils (46 sites) and at statistically greater relative abundances (per 16S rRNA gene) than in soils from the other land use categories. When the cropland gene data was separated by sites that had received dairy manure, dairy wastewater, and/or biosolids (27 sites), it was revealed that the genes [except tet(B)] were found at statistically greater abundances (7- to 22-fold higher on average) than in soils that were not treated. The results from this study provide convincing evidence that manure/biosolids use in Idaho cropland soils increases the expansion of antibiotic resistance-related determinants.
