近些年,江西桃红岭梅花鹿国家级自然保护区植被正向演替明显,大量梅花鹿(Cervus nippon)开始向保护区外围扩散和聚集,调查桃红岭梅花鹿潜在病原携带情况,有利于掌握其种群健康状况,进而制定精确的保护管理对策,因此在该保护区不同区域(核心区、缓冲区和实验区)采集梅花鹿新鲜粪便样品,并基于宏基因组测序技术分析其病原携带情况.结果表明:桃红岭梅花鹿携带病原微生物包括细菌、真菌、放线菌、支原体、衣原体和螺旋体,共34属63种,其中包含大量人兽共患病病原;病原丰度最高的5个属分别是拟梭菌属(Clostridioides)、李斯特菌属(Listeria)、克雷伯氏菌属(Klebsiella)、志贺氏菌属(Shigella)和沙门氏菌属(Salmonella),丰度最高的5个种分别是艰难拟梭菌(Clostridioides difficile)、单核增生李斯特氏菌(Listeria mono-cytogenes)、肺炎克雷伯氏菌(Klebsiella pneumoniae)、肠炎沙门氏菌(Salmonella enter-itidis)和福氏志贺氏菌(Shigella flexneri);不同研究区域中,核心区梅花鹿携带病原数量显著低于缓冲区和实验区.以上结果表明,桃红岭梅花鹿携带有多种病原,存在一定疫病发生风险.建议在保护区核心区积极开展栖息地矮化工作,同时开展高危病原的持续性监测及预警,并加强对保护区外围扩散梅花鹿种群的保护管理.
Preliminary Investigation of Potential Pathogens of Sika Deer in Taohongling,Jiangxi Based on Metagenomics
In recent years,positive vegetation succession is obvious in Jiangxi Taohongling Sika Deer National Nature Re-serve,and a large number of sika deer(Cervus nippon)begin to spread and gather in the periphery of the reserve.To in-vestigate the potential pathogen carrying situation of the sika deer in the reserve is helpful to grasp the health status of its population,so as to formulate precise conservation and management countermeasures.We collected the fresh fecal samples of sika deer from different zones of the reserve(core zone,buffer zone and experimental zone)and analyzed the pathogen carring status using metagenomic sequencing technology.The results showed that the sika deer in Taohongling Reserve carried 63 species of pathogenic microorganisms in 34 genus,including bacteria,fungi,actinomycetes,mycoplas-mas,chlamydia and spirochetes,totaling 63 species in 34 genus,and most of which were zoonotic pathogens.The five ge-nus with the highest abundance of pathogens were Clostridioides,Listeria,Klebsiella,Shigella,and Salmonella,and the five species with the highest abundance were Clostridioides difficile,Listeria monocytogenes,Klebsiella pneumoniae,Sal-monella enteritidis,and Shigella flexneri.The number of pathogens carried by sika deer in the core zone was significantly lower than that in the buffer zone and experimental zone.Our results indicated that the sika deer in Taohongling Reserve carry a variety of pathogens,with a certen risk of epidemics occurrence.It is recommended to carry out habitat dwarfing in the core zone,and at the same time,to carry out continuous monitoring and early warning of high-risk pathogens.In addi-tion,conservation management of the proliferating sika deer population should be strengthened.
