肠道菌群对动物免疫系统早期发育的影响

Effect of Intestinal Flora on Animal Early Development of Immune System

肠道是动物机体最大的免疫器官,肠道菌群是定植在肠道内的微生物群落。最早定植在动物体内的细菌源于动物在环境中随机接触的第一类细菌,并结合其他环境因素影响后续微生物种类的进入。微生物与免疫的互作在免疫系统的早期发育中起着重要作用,一旦中断将导致潜在、持久的免疫异常,所以微生物的早期定植有助于提高机体的免疫力。本文主要综述了肠道菌群对畜禽免疫系统早期发育的影响,探讨在养殖业中如何促进畜禽健康、提高生产成绩。

Gastrointestine was viewed as the largest immune organ of animals, intestinal flora was the microbial communities which was inhabited in. The earliest colonized bacteria in animals was primarily determined by its randomly contact the first bacteria in the environment, and then combining other environmental factors influenced the subsequent microbial species. However, microbes and immune system interactions play a crucial role in the early immune system development, once was interrupted which would cause potential and lasting immune abnormalities. Therefore microbes, especially probiotics original inoculation will obviously enhance the immune system lever. This review mainly summarized the interaction of intestinal flora and the early immune system development, in order to promote the animal＇s health and improve the production performance.
