Abstract
Antibiotic resistance genes (ARGs) have raised numerous concerns in recent years as emerging environmental contaminants. At present, research on environmental contamination by antibiotics focuses on medical, animal husbandry, and aquaculture fields, with few studies on environmental contamination by agricultural antibiotics in the field of plant protection. Wuyiencin is a low toxicity, high efficiency, and broad-spectrum agricultural antibiotic. It has been widely used in agricultural production and it effectively controls crop fungal diseases. In the present study, pot experiments with four soil treatments (A, B, C and D) were set up in a greenhouse to investigate the effect of the application of wuyiencin on the fate of typical ARGs and microbial community. Eight typical ARGs were detected by real-time PCR and the microbial communities were analyzed using high-throughput sequencing. The results showed that wuyiencin neither significantly influenced ARG abundance and absolute gene copy numbers, nor significantly varied microbial community among treatments. Since it only was short-term results, and the detection number of ARGs was limited, whether wuyiencin is safe or not to ecological environment when using for long-term will need further deep research.
Highlights
Large-scale antibiotic production and application over more than 70 years has contributed greatly to human health and agricultural production
There are more than 20 kinds of agricultural antibiotics and more than 2000 kinds of dosage forms are used in agricultural production
Wuyiencin is produced by Streptomyces ahygroscopicus var. wuyiensis, which was isolated from a natural soil habitat in Wuyi Mountain, Fujian Province, China, in 197918
Summary
Large-scale antibiotic production and application over more than 70 years has contributed greatly to human health and agricultural production. Antibiotic resistance genes (ARGs) enter various pathogens through horizontal gene transfer and pose risks to human health and environmental safety[6]. They are safe for humans, animals, and non-target organisms. They are environmentally friendly, are not resisted, but decompose readily. Agricultural antibiotics have been considered as one of the most promising tools for plant-disease control, with numerous potential benefits for nutrition, health, and food production. Owing to the use of irrigation and utilization of sludge as manure, copious amounts of antibiotics enter farmlands, resulting in the enrichment of antibiotic-resistant bacteria and ARGs in farmland soil
