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(xì)菌群落組成，多樣性和起源
