分析了草鱼卵和仔鱼中的细菌群落结构。在草鱼早期发育阶段，草鱼体内存在变形菌门、拟杆菌门、疣微菌门、浮游菌门和厚壁菌门5个细菌门。然而，细菌群落的组成在不同的发展阶段之间的变化。在卵中，细菌群落以变形菌门为主，而在幼虫中，细菌群落以拟杆菌门为主。受精期（FS）卵中除大部分（> 50%）未培养细菌外，鞘氨醇杆菌属（14.75%）和不动杆菌属（13.11%）是最丰富的类群。然而，气单胞菌是最丰富的组，从40.54%到61.76%的鸡蛋在卵裂（CS），囊胚（BS），器官分化（ODS）和孵化期（HS）。在第一次摄食后（OW）的幼虫中，噬几丁菌科（79.41%）形成了优势细菌群落。通过统计分析进一步证实了细菌群落的变化，表明在FS，从CS到HS和OW的鸡蛋中的细菌群落存在显著差异。但从CS到HS鸡蛋的细菌群落没有发现显着差异。此外，本研究揭示了与噬几丁菌科相关的细菌从CS持续到OW，表明这些细菌形成了鱼的本地微生物群的一部分。
Bacterial communities in eggs and larvae of grass carp were analysed. During the early-developmental stages, grass carp harboured five bacterial phyla, i.e. Proteobacteria, Bacteroidetes, Verrucomicrobia, Planctomycetes and Firmicutes. However, the composition of bacterial communities varied among the different developmental stages. In eggs, the bacterial communities were dominated by Proteobacteria, while in larvae the dominant bacterial community was Bacterioidetes. With the exception of a large proportion (>50%) of uncultured bacteria, Sphingobacterium (14.75%) and Acinetobacter (13.11%) were the most abundant groups in eggs at the fertilization stage (FS). However, Aermonas was the most abundant group, ranging from 40.54% to 61.76% in eggs at the cleavage (CS), blastula (BS), organ differentiation (ODS) and hatching stages (HS). In larvae after first ingestion (OW), Chitinophagaceae (79.41%) formed the predominant bacterial community. Changes in the bacterial community were further confirmed by statistical analysis, which demonstrated significant differences in the bacterial communities of eggs at FS, eggs from CS to HS and OW. However, no significant difference was found in bacterial communities of eggs from CS to HS. Furthermore, the present study revealed that bacteria related to Chitinophagaceae persisted from CS to OW, suggesting that these bacteria form part of the autochthonous microbiota of the fish.
