摘　　要：为探究宽体金线蛭肠道与土壤环境中细菌群落多样性差异,本研究使用高通量测序技术测定了该物种肠道和土壤中的细菌群落。结果表明,金线蛭肠道和土壤样品中的细菌群落多样性和群落结构存在明显差异,表明土壤对肠道细菌群落的建立影响不大。与土壤样品相比,肠道样品中的细菌丰富度和多样性明显降低;肠道中的优势菌门为厚壁菌门(Firmicutes)40.64%、变形杆菌(Proteobacteria)28.94%和拟杆菌门(Bacteroidota)16.20%等,土壤中的优势菌门为变形杆菌48.95%、拟杆菌门16.69%和放线菌门(Actinobacteriota)14.85%等;肠道中优势属为气单胞菌属(Aeromonas)23.76%、鲸杆菌属(Cetobacterium)9.98%和刺骨鱼属(Epulopiscium)8.16%。土壤类群中优势属为氢噬胞菌属(Hydrogenophaga)6.16%、黄杆菌属(Flavobacterium)11.36%和气单胞菌属5.26%。两者在转运通路、碳循环通路和免疫等方面存在差异。研究结果为了解宽体金线蛭的肠道细菌群落及与土壤环境间的关系提供参考。To investigate the diversity of bacterial communities in the intestinal tract of Whitmania pigra and soil of enviroment,high-throughput sequencing technology was used to determine the bacterial communities in the intestinal tract of this species.and soil of enviroment The results showed that there were significant differences in bacterial community diversity between and community structure intestinal and soil samples,indicated that soil had little effect on the establishment of intestinal bacterial community.Compared with soil samples,the richness and diversity of bacteria in intestinal samples were significantly reduced.The dominant bacteria in the gut were Firmicutes 40.64%,Proteobacteria 28.94% and Bacteroidota 16.20%.The dominant bacteria in soil were Proteobacteria 48.95%,Bacteroides 16.69% and Actinobacteriota 14.85%.The dominant genera were Aeromonas 23.76%,Cetobacterium 9.98% and Epulopiscium 8.16%.The dominant genera of the soil groups were Hydrogenophaga 6.16%,Flavobacterium 11.36% and Aeromonas 5.26%.There were differences in transport pathway,carbon cycle and immunity between the two.The research results provided a reference for understanding the relationship between intestinal bacterial community of Whitmania pigraand and soil environment.
