SSU rRNA metabarcode of bacteria in trout cultured in Angara river

Composition of bacterial communities associated with cultured trout sampled from a fish farm on Angara river. A chronic bacterial disease of unknown etiology was observed on this fish farm; to identify the pathogen for further studies, visibly diseased and apparently healthy fishes were taken into analysis. The primary goal of this analysis was to identify the pathogen, which turned out to be Flavobacterium psychrophilum. Although the community in diseased fishes is heavily dominated by this bacterium, other bacteria inhabiting trout were also detected.

本数据集涵盖安加拉河（Angara River）某渔场采集的养殖虹鳟相关细菌群落组成信息。该渔场曾出现病因不明的慢性细菌性疾病；为明确致病菌以推进后续研究，研究人员采集了外观患病与外观健康的虹鳟样本开展分析。本次分析的核心目标为鉴定致病菌，最终确认其为嗜冷黄杆菌（Flavobacterium psychrophilum）。尽管患病虹鳟的细菌群落以该菌占据绝对主导地位，但研究同时也检测到了虹鳟体内定植的其他细菌类群。
