微生物组基础知识

含细菌的肠绒毛

胃肠道是身体与环境的最大接触面。1肠道的作用远远不止消化。

虽然胃肠道（肠道）是食物消化和营养吸收的中心，但它对宠物的整体健康也起着关键作用。

肠道微生物组的已知功能包括：2、3

  • 收集食物以作为能量
  • 通过发酵和代谢活动为宿主提供营养
  • 分解膳食纤维
  • 形成免疫系统并维持稳态
  • 处理多糖和维生素
  • 产生激素
  • 抵御肠道病原体

肠道是数百种不同的细菌和其他微生物（如原生动物、古生菌、病毒和真菌）的家园。

肠道中寄生着数以亿计的微生物 - 肠道中的微生物细胞数量至少与全身细胞数量相同。4当前文献估计有 1010-1014 个微生物细胞。2这些常居微生物（或共生菌）在能量调节、矿物质吸收、维生素合成、肠道屏障功能和免疫系统功能中发挥作用。它们还能提供抵抗病原体的屏障，并帮助滋养肠道。

肠道微生物组构成了肠道和大脑之间双向相互作用的关键部分，称为肠脑轴，5越来越多的证据表明，微生物组会影响其他器官的健康，如皮肤、6心脏和肾脏。
