Antibiotics and antibiotic resistance genes in agricultural soils: A systematic analysis

Jie Wu et al.

Summary: Misuse and overuse of antibiotics have led to the rise of antimicrobial resistance. In agricultural soils, antibiotics and antibiotic resistance genes (ARGs) are mostly found due to the application of livestock and organic wastes. Cattle manure, chicken manure, swine manure, and sewage sludge are the primary sources of antibiotics and ARGs in agricultural soils. Sulfonamides, tetracyclines, fluoroquinolones, and corresponding ARGs are the major types of pollution. Land-use type, soil, and climatic factors affect the concentrations of antibiotics and abundances of ARGs. Mobile genetic elements (MGEs), especially the sul1 gene, play a vital role in promoting the dissemination of ARGs. Better management of antibiotic and ARG contamination in agricultural soils is important for human health.

Pollution characteristics of livestock faeces and the key driver of the spread of antibiotic resistance genes

Zhengfu Yue et al.

Summary: The study found that piglet faeces had the highest levels of antibiotics and heavy metals, with sulphonamides (SAs) explaining 36.5% of the variance in the bacterial community and significantly related to 8 genes. Structural equation modelling indicated that SAs increased the abundance of ARGs through horizontal and vertical transfer pathways.
