Microbial diversity and skin mucosal microbiota in farmed Atlantic salmon with ulcerative disorders, raw sequence reads

The Norwegian aquaculture of Atlantic salmon Salmo salar is hampered by ulcerative disorders associated with bacterial infections. Studying the composition of microbial communities on skin mucus, and how the microbiota is structured in ulcers will enhance our understanding of ulcer etiology. To achieve this we used seawater farmed Atlantic salmon and sampled the base and edge of ulcers at the end of winter (April) and at the end of summer (September), in addition to skin-mucus of healthy individuals. In order to assess microbiota associated to the host and to get a better insight into the environmental ecology we additionally sampled the seawater column and sediment layer underneath the farm facility in addition to the distal intestine of Atlantic salmon.

挪威海产大西洋鲑鱼（Salmo salar）的养殖受到与细菌感染相关的溃疡性疾病的阻碍。研究皮肤粘液中微生物群的组成及其在溃疡中的结构，将有助于我们深入了解溃疡的病因。为此，我们采用了海水养殖的大西洋鲑鱼，在冬季末（四月）和夏季末（九月）对溃疡的底部和边缘进行采样，同时采集了健康个体的皮肤粘液。为了评估与宿主相关的微生物群，并更深入地了解环境生态学，我们还对养殖设施下方的海水柱和沉积层进行了采样，以及采集了大西洋鲑鱼的远端肠道样本。
