Beneficial effects of probiotics on Litopenaeus vannamei growth and immunity via the recruitment of gut Rhodobacteraceae symbionts

There is evidence that probiotics addition enriches the gut Rhodobacteraceae species that are key and beneficial symbionts in shrimp Litopenaeus vannamei fitness. Thus, it is of great significance to explore how the Rhodobacteraceae community implicates the assembly of shrimp gut microbiota for optimizing probiotics application. Here, we explored whether probiotics benefited shrimp health and fitness via the recruitment of gut Rhodobacteraceae commensals.

已有证据显示，添加益生菌（probiotics）可富集凡纳滨对虾（Litopenaeus vannamei）肠道内作为其健康关键有益共生菌的红杆菌科（Rhodobacteraceae）物种。因此，探究红杆菌科群落如何参与对虾肠道微生物群（gut microbiota）的组装过程，对于优化益生菌的应用具有重要意义。本研究旨在探明益生菌是否可通过招募肠道红杆菌科共生菌，从而增进对虾的健康与生存状态。
