摘要: 目的:探讨吡嗪酰胺对小鼠肠道菌群的影响。方法:设置溶剂对照组、吡嗪酰胺低剂量组和吡嗪酰胺高剂量组,每组10
只,采集3组小鼠新鲜粪便进行16S rRNA测序,并利用生物信息学方法分析小鼠肠道菌群多样性。结果:吡嗪酰胺低剂量组、
高剂量组和溶剂对照组肠道菌群在门水平上以拟杆菌门和厚壁菌门为优势菌群,其占比依次为47.02%、51.46%,56.24%、
41.65%和76.14%、20.83%。属水平上,吡嗪酰胺低剂量组以拟杆菌属(8.42%)和颤螺旋菌属(1.41%)为主;吡嗪酰胺高剂量组
以乳酸杆菌属(2.74%)、Odoribacter(1.20%)和拟杆菌属(1.14%)为主;溶剂对照组以普雷沃菌属(3.54%)和双歧杆菌属
(1.81%)为主。相对于溶剂对照组,吡嗪酰胺组的氨基酸、能量和多糖代谢均显著降低(P < 0.05)。结论:吡嗪酰胺能够改变肠
道菌群结构组成及代谢功能。

Abstract: Objective: To investigate the effects of pyrazinamide on intestinal flora in mice. Methods: A solvent control group, a lowdose
pyrazinamide group and a high-dose pyrazinamide group were set up with 10 mice in each group. Three groups of fresh feces were
collected for 16S rRNA sequencing and analyzed by bioinformatics methods to determine the diversity of mouse intestinal flora.
Results: At the phylum level, the low-dose group, the high-dose group, and the solvent control group are dominated by Bacteroidetes
and Firmicutes, and their dominant flora accounted for 47.02%, 51.46%, 56.24%, 41.65%, 76.14% and 20.83%, respectively. At the
genus level, the low-dose group is dominated by Bacteroides(8.42%)and Oscillospira(1.41%); the high-dose group is dominated by
Lactobacillus(2.74%), Odoribacter(1.20%)and Bacteroides(1.14%); the solvent control group is mainly Prevotella(3.54%)and
Bifidobacterium(1.81%). Compared with the solvent control group, the amino acid, energy and polysaccharide metabolism of the
pyrazinamide group were significantly reduced(P < 0.05). Conclusion: Pyrazinamide can change the composition and metabolic
function of intestinal flora.

Key words: pyrazinamide, intestinal flora, 16S rRNA
