Bacterial antibiotic resistance (AR) is a global human health issue. Although traditional AR research is primarily conducted on human pathogens, studies in the past ten years on soil microbial communities have revealed enormous diversity of bacterial AR genes, which was hence termed the soil resistome. Research conducted in Arctic and Antarctic regions, where anthropogenic activities are limited, have produced great insights into the evolution and proliferation of bacterial AR genes. As the “Third Pole”, the Tibetan Plateau has its unique geological, solar, hydrological, and climatic patterns, which may uniquely shape its soil resistome. This project aims to study the diversity of soil resistome on the Tibetan Plateau, and the research approach involves field sampling, laboratory sample processing, high throughput metagenomic sequencing, and bioinformatic data analysis. The project design maximizes the complementary technical expertise and infrastructure resources of the applicant and the collaborator. The successful implementation of the project will initiate a new research field based on the unique geography of the Tibetan Plateau, and will contribute to the advancement of global soil resistome research.
细菌抗生素抗药性已经成为一个受全球关注的,与人类健康密切相广的问题。近十年的研究发现在土壤微生物群落中包含的细菌抗药性基因拥有更高的多样性,并因此诞生了一个被称为土壤细菌耐药基因组学的新学科分支。在受人类活动影响较小的北极和南极中展开的相关研究已经就细菌耐药基因的进化和传播产生了重要的科学发现。青藏高原作为“世界第三极”,其独特的地质、日照、降水、和气候等自然环境因素及其季节变化也可能对土壤细菌耐药基因组的多样性产生独特的影响。本课题将采用现场采样、实验室样品处理、高通量宏基因组测序、以及生物信息数据分析相结合的实验方法来研究青藏高原高寒地区土壤细菌耐药基因组的多样性。课题的设计有机地整合了申请人和合作者的技术和资源优势互补,项目的成功实施可以填补我国在此领域的空白,并对全球范围内整个土壤细菌耐药基因组学学科的发展作出贡献。
