Composition, Diversity, and Origin of the Bacterial Community in Grass Carp Intestine

Abstract
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.

草魚腸道中的細菌群落組成，多樣性和起源

總結(jié)如下：
腸道菌群已成為一個不可分割的組成部分主機，并日益受到重視。然而，對于許多
家養(yǎng)動物，微生物上的信息是不夠的，更多的努力，應(yīng)充分發(fā)揮管理
胃腸道細菌群落。了解影響因素，微生物群落的組成
主機消化道是必不可少的管理或改善微生物群落組成。在本研究中，
16S rRNA基因序列為基礎(chǔ)的比較草魚細菌群落（草魚）
腸內(nèi)容和養(yǎng)魚相關(guān)的環(huán)境中進行。結(jié)果表明，魚腸道
微生物藏著許多包括纖維素分解菌，明串珠Anoxybacillus序列，
