肠道菌群已成为宿主不可或缺的组成部分，并日益受到重视。然而，对于许多家畜来说，关于微生物群的信息是不够的，应该付出更多的努力来管理胃肠道细菌群落。了解影响宿主消化道微生物群落组成的因素对于管理或改善微生物群落组成至关重要。本研究利用16S rRNA基因序列对草鱼（Ctenopharyngodon idellus）肠道内容物和养殖环境中的细菌群落进行了比较。结果表明，鱼类肠道微生物群中含有许多纤维素分解菌，包括Anoxybacillus、Leuconostoc、Clostridium、Actinomyces和Citrobacter的相关序列。草鱼肠道内容物中最丰富的细菌操作分类单位（OTU）是与饲料消化相关的细菌。此外，潜在的病原菌和益生菌是肠道微生物群的重要成员。进一步的分析表明，草鱼肠道拥有由变形菌门、厚壁菌门和放线菌门组成的核心微生物群。比较分析表明，肠道内容物中的细菌群落与养殖水体和沉积物中的细菌群落最为相似。然而，饲料对肠道菌群的组成也有显著影响。
Gut microbiota has become an integral component of the host, and received increasing attention. However, for many domestic animals, information on the microbiota is insufficient and more effort should be exerted to manage the gastrointestinal bacterial community. Understanding the factors that influence the composition of microbial community in the host alimentary canal is essential to manage or improve the microbial community composition. In the present study, 16S rRNA gene sequence-based comparisons of the bacterial communities in the grass carp (Ctenopharyngodon idellus) intestinal contents and fish culture-associated environments are performed. The results show that the fish intestinal microbiota harbors many cellulose-decomposing bacteria, including sequences related to Anoxybacillus, Leuconostoc, Clostridium, Actinomyces, and Citrobacter. The most abundant bacterial operational taxonomic units (OTUs) in the grass carp intestinal content are those related to feed digestion. In addition, the potential pathogens and probiotics are important members of the intestinal microbiota. Further analyses show that grass carp intestine holds a core microbiota composed of Proteobacteria, Firmicutes, and Actinobacteria. The comparison analyses reveal that the bacterial community in the intestinal contents is most similar to those from the culture water and sediment. However, feed also plays significant influence on the composition of gut microbiota.
