摘要:

抗性基因mcr-1作为介导细菌对"最后一道防线"抗生素黏菌素产生耐药性的关键遗传元件, 一经发现就成为当前研究热点之一, 对公共卫生构成潜在威胁。本文旨在探讨种养循环模式下黏菌素抗性基因mcr-1的归趋。本文首先概述了mcr-1的抗性机制、水平传播、适应性代价和补偿性进化, 然后介绍了mcr-1在种养循环系统中的赋存、转归与水平传播特征, 并探讨了影响其传播的关键因素, 最后提出相应的防控措施, 以期为循环农业的高质量发展和公共卫生安全提供参考。

Abstract:

The resistance gene mcr-1, as a key genetic element mediating bacterial resistance to "last-resort" antibiotic colistin, has become a research hotspot since its discovery and poses a potential threat to public health. This paper aims to investigate the fate of colistin resistance gene mcr-1 in the planting-breeding cycling system. First, we summarize the resistance mechanisms, horizontal gene transfer, fitness costs, and compensatory evolution of mcr-1. Subsequently, we examine its occurrence, fate, and horizontal transmission characteristics in the planting-breeding cycling system, along with the key factors influencing its dissemination. Finally, we propose corresponding control measures, providing insights for high-quality development of circular agriculture and public health security.

Key words: crop-livestock integrated farming system, antibiotic resistance gene, mcr-1, fate, horizontal gene transfer, colistin
