Prairie strips' effect on transport of antimicrobial resistance indicators in poultry litter.

Poultry litter is a valuable nutrient resource for agricultural production but is also a potential source for introducing antibiotic resistance genes (ARGs) and litter-associated bacteria (LAB) to the environment. Prairie strips have been demonstrated as an effective conservation practice to improve environmental quality in agroecosystems. This research aims to assess prairie strips' potential for reducing the transport of LAB and ARGs in runoff after litter application.

Antibiotic resistance gene dissipation in soil microcosms amended with antibiotics and swine manure.

The use of antibiotics in animal agriculture has exacerbated the presence of both antibiotic resistance genes (ARGs) and residual antibiotics excreted in animal manure. Field application of this manure is a common practice because its nutrient rich material can benefit crop growth. However, this practice can also introduce antibiotics and ARGs into nonagricultural settings.
