From grasslands to genes: exploring the major microbial drivers of antibiotic-resistance in microhabitats under persistent overgrazing.

ABSTRACT:

Background

The extensive use of antibiotics in the global livestock industry in recent decades has accelerated the accumulation and dissemination of antibiotic-resistance genes (ARGs) within terrestrial ecosystems. This occurs due to the limited absorption of most antibiotics, leading to their release into the environment through feces and urine. This poses a significant threat to both the environment and human health. However, the response of antibiotic-resistant microorganisms and their ARGs in grasslands to prolonged grazing, as well as the primary microbial taxa driving the ARG distribution, remain poorly understood, especially within various microhabitats. In this study, we characterized ARGs in the phyllosphere, litter, and soil after decades of livestock grazing in a meadow
