摘要: 【目的】 对比分析圈养条件下腹泻和健康林麝粪便菌群组成和多样性差异,找出具有显著差异的生物标志菌群,为防治林麝腹泻提供参考。【方法】 利用Illumina NovaSeq 6000平台对腹泻(D组,n=10)和健康(H组,n=10)林麝粪便菌群总DNA中16S rRNA基因V3-V4区测序,分析D和H组林麝粪便在菌群组成、多样性、标志菌群和功能之间的差异。【结果】 Alpha多样性分析结果显示,D组林麝粪便中菌群的ACE和Chao1指数显著高于H组(P<0.05),Simpson和Shannon指数低于H组,其中Simpson指数差异显著(P<0.05);Beta多样性分析结果显示,D和H组间的菌群群落结构存在显著差异(R2=0.55,P=0.001);门水平上,厚壁菌门(Firmicutes)是2组的共有优势菌门,差异菌门包括拟杆菌门(Bacteroidota)、变形菌门(Proteobacteria)和放线菌门(Actinobacteriota)。属水平上,瘤胃菌科UCG 005属(Ruminococcaceae_UCG_005)是2组的共有优势菌属,差异菌属包括不动杆菌属(Acinetobacter)、拟杆菌属(Bacteroides)和理研菌科RC9属(Rikenellaceae_RC9_gut_group);D组有奥尔森菌属(Olsenella)等23个标志菌群,H组有理研菌科RC9属等15个标志菌群;基于PICRUSt2功能预测发现,与H组相比,D组膜转运、氨基酸运输与代谢、内分泌与代谢疾病等功能丰度显著增加(P<0.05),而次级代谢物的合成、细胞增殖与凋亡、免疫防御等显著下降(P<0.05)。【结论】 腹泻会显著改变林麝肠道菌群组成、菌群多样性和功能丰度,肠道中不动杆菌属、奥尔森菌属和理研菌科RC9属等菌群的丰度是判断林麝肠道健康状态的特征标志菌群。

Abstract: 【Objective】 This study aimed to comparatively analyze the differences in the composition and diversity of fecal flora between diarrheal and healthy forest musk deer under captive conditions,and identify the biomarker flora with significant differences,so as to provide a reference for the prevention and treatment of diarrhea in forest musk deer. 【Method】 Illumina NovaSeq 6000 platform was used to sequence the V3-V4 region of 16S rRNA gene in the total DNA of fecal flora of diarrhea (group D,n=10) and healthy (group H,n=10) forest musk deer,and the differences between groups D and H in the composition,diversity,biomarker flora and functions of the flora were analyzed. 【Result】 Alpha diversity analysis results showed that ACE and Chao1 indices of fecal microfiota of forest musk deer in group D were significantly higher than those of group H (P<0.05),while the Simpson and Shannon indices were lower than those of group H,with a significant difference in the Simpson index between the two groups (P<0.05).The results of Beta diversity showed that there was a significant difference in the community structure of flora between groups D and H (R2=0.55,P=0.001).The results showed that at phylum level,Firmicutes was the dominant phylum in both groups.The differential phyla included Bacteroidota,Proteobacteria and Actinobacteriota.At genus level,Ruminococcaceae_UCG_005 emerged as the common dominant genus in both groups,while the differential genera included Acinetobacter,Bacteroides and Rikenellaceae_RC9_gut_group.Group D contained 23 marker microbiota such as Olsenella,and group H had 15 marker microbiota such as Rikenellaceae_RC9_gut_group.Based on PICRUSt2 function prediction,it was found that compared with group H,group D was significantly increased in membrane transport,amino acid transport and metabolism,endocrine and metabolic diseases (P<0.05),and significantly decreased in the biosynthesis of other secondary metabolites,cell growth and death,defense mechanisms (P<0.05). 【Conclusion】 Diarrhea could significantly change the composition,diversity and functional abundance of the intestinal flora of forest musk deer.The abundance of Acinetobacter,Olsenella and Rikenellaceae_RC9_gut_group in the gut were characteristic markers of the intestinal health of forest musk deer.
