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.
The Genome Sequencing and Analysis of Proteus penneri Strain F2d Isolated from Cervus nippon
In order to explore the pathogenicity and drug resistance mechanism of Proteus pennerifrom Cervus nippon,a pathogenic strain of Proteus penneri was isolated from the lung organs of dead Cervus nippon in Yunnan Wildlife Park.The whole genome of the isolated strain F2d was sequenced by the second generation sequencing technology,and the whole genome sequence of F2d obtained by sequencing was annotated into the databases of virulence factor,drug resistance gene,and metabolic pathway.The results of virulence factor database annotation showed that the strain contained viru-lence factors of adherence,nutritional/metabolic factor,motility,immune modulation and other types.The annotation re-sults of the comprehensive antibiotic research database showed that strain F2d was resistant to many antibiotics such as β-lactams,aminoglycosides,tetracyclines and fluoroquinolones,and had many genes encoding the mechanism of antibiotic efflux.The annotation results of metabolic pathway database showed that the annotated genes were enriched in 42 path-ways,and the number of metabolism related annotated genes was the largest,with a total of 2,250 genes distributed in 12 pathways.Using whole genome sequencing technology to analyze the metabolic characteristics,pathogenicity and drug re-sistance of Proteus penneri F2d from deer can provide a theoretical basis for the prevention of Proteus penneri infection and the development of related drugs.
