为探究鹿源彭氏变形杆菌（Proteus penneri）致病及耐药机制，利用二代测序技术对从云南野生动物园病死梅花鹿（Cervus nippon）肺组织中分离鉴定出的1株彭氏变形杆菌F2d株进行基因组测序，将获得的F2d株基因组序列注释到毒力因子、耐药基因和代谢通路等数据库中。毒力因子数据库注释结果显示，菌株含黏附、营养代谢、运动和免疫调节等类型毒力因子；耐药基因数据库注释结果显示，F2d株对β-内酰胺类、四环素类、黏菌素类和磺胺类等多种抗生素耐药，并且携带多种抗生素外排机制编码基因；代谢通路数据库注释结果显示，注释的基因富集在42个通路上，其中新陈代谢相关注释的基因数量最多，共有2 250个基因分布在12个通路上。利用基因组测序技术分析鹿源彭氏杆菌F2d株致病性、耐药情况及代谢特点，可为预防彭氏变形杆菌感染和相关药物的研发提供理论依据。

Leisure agriculture and rural tourism, as a fusion of primary, secondary, and tertiary industries in rural areas, have played an important role in promoting agricultural quality and efficiency, driving employment and income growth for farmers, expanding consumer demand for residents, inheriting agricultural civilization, building beautiful villages, promoting urban-rural integration, and achieving common prosperity. However, the development of leisure agriculture and rural tourism industry has long faced difficulties in securing construction land, especially newly added construction land, which has severely restricted its development. Based on the analysis of the current situation and problems of leisure agriculture and rural tourism land in Ningbo City, the article introduces the model of spot-like land supply, with relevant development suggestions. Taking Xiangshan County as an example to carry out different spatial guidance zoning of the spot-like land supply type, providing special data support for the promotion and application of spot-like land supply in rural industries.
