Metagenome of grass carp intestinal contents and mucosa

Intestinal microbiota is a complex ecosystem and plays an important role in host biology. More and more researches focus on the bacterial community of the host intestine. However, there is still limited information on a better understanding of fish intestinal microbiota. Due to the importance of grass carp in aquaculture of China, it’s necessary to pay attention to its intestinal microbiota. In this study, the composition of bacterial communities in intestinal contents and mucosa of grass carp was analyzed by 454 pyrosequencing.

肠道微生物群（intestinal microbiota）是一类复杂的生态系统，在宿主生命活动中发挥着关键作用。当前越来越多的研究聚焦于宿主肠道的细菌群落，但目前关于鱼类肠道微生物群的系统性认知仍存在较多局限。鉴于草鱼在中国水产养殖业中的重要地位，对其肠道微生物群展开研究具有重要的现实意义。本研究采用454焦磷酸测序（454 pyrosequencing）技术，对草鱼肠道内容物与肠黏膜中的细菌群落组成进行了分析。
