Abstract:
It is necessary to complement next-generation sequencing data on the soil resistome with theoretical knowledge provided by ecological studies regarding the spread of antibiotic resistant bacteria (ARB) in the abiotic and, especially, biotic fraction of the soil ecosystem. Particularly, when ARB enter agricultural soils as a consequence of the application of animal manure as fertilizer, from a microbial ecology perspective, it is important to know their fate along the soil food web, that is, throughout that complex network of feeding interactions among members of the soil biota that has crucial effects on species richness and ecosystem productivity and stability. It is critical to study how the ARB that enter the soil through the application of manure can reach other taxonomical groups (e.g., fungi, protists, nematodes, arthropods, earthworms), paying special attention to their presence in the gut microbiomes of mesofauna-macrofauna and to the possibilities for horizontal gene transfer of antibiotic resistant genes.
摘要:
有必要用生态学研究提供的有关抗生素抗性细菌(ARB)在非生物和植物中传播的理论知识来补充土壤抗性的下一代测序数据,尤其是,土壤生态系统的生物部分。特别是,当ARB由于施用动物粪便作为肥料而进入农业土壤时,从微生物生态学的角度来看,重要的是要知道它们在土壤食物网上的命运,也就是说,贯穿土壤生物群成员之间复杂的摄食相互作用网络,这对物种丰富度,生态系统生产力和稳定性具有至关重要的影响。研究通过施用粪肥进入土壤的ARB如何到达其他分类学组(例如,真菌,原生生物,线虫,节肢动物,蚯蚓),特别注意它们在中层动物-大型动物的肠道微生物组中的存在,以及抗生素抗性基因水平基因转移的可能性。
