摘要: 胃肠道菌群的变化在动物健康和疾病中扮演重要角色,越来越多的研究证据将机体的免疫系统与胃肠道菌群联系了起来。其主要机制可能是菌群紊乱导致菌群-免疫互作失调,营养代谢与能量调控失衡,免疫系统受损,最后诱发疾病。围产期奶牛面临维持机体正常生理代谢的严峻挑战,奶牛在围产期容易感染多种疾病,给牧场带来了严重的经济损失。最近的研究表明,围产期奶牛瘤胃菌群紊乱是导致生产性疾病发生的重要诱因,胃肠道菌群与宿主黏膜免疫系统之间的互作在维持胃肠道动态平衡和抑制炎症中起着关键作用。本文综述了围产期奶牛胃肠道菌群变化特征及胃肠道黏膜免疫系统组成,并讨论了菌群与黏膜免疫互作机制在维持奶牛健康中发挥的重要作用,最后介绍了菌群紊乱与免疫失衡介导的奶牛生产性疾病,旨在为探索围产期奶牛饲养管理及疾病防控提供新思路。

Abstract: The changes of gastrointestinal flora play an important role in animal health and disease, and more and more research evidence has linked the immune system with gastrointestinal flora. The main mechanism may be that the disturbance of flora leads to the imbalance of flora-immune interaction, the imbalance of nutritional metabolism and energy regulation, the damage of immune system, and finally induces disease. Perinatal dairy cows face the severe challenge of maintaining normal physiological metabolism. Dairy cows are easy to be infected with a variety of diseases during the perinatal period, which brings serious economic losses to the pasture. Recent studies have shown that the disturbance of rumen flora in perinatal dairy cows is an important cause of productive diseases, and the dynamic interaction between gastrointestinal flora and host mucosal immune system plays a key role in maintaining gastrointestinal dynamic balance and inhibiting inflammation. In this paper, the changes of gastrointestinal microflora and the composition of gastrointestinal mucosal immune system in perinatal dairy cows were reviewed, and the important role of the interaction mechanism of microflora and mucosal immunity in maintaining the health of dairy cows was discussed. Finally, the productive diseases of dairy cows mediated by flora disorder and immune imbalance were introduced in order to provide new ideas for perinatal cow feeding and management and disease prevention and control.

Key words: perinatal dairy cows, gastrointestinal microbiota, mucosal immunity, dysbacteriosis
