This study focused on and conducted stress experiments at salinity levels of 20‱ and 40‱. Intestinal histological changes and the structural characteristics of the intestinal flora of under salinity stress were analyzed. The results show that acute salinity stress inflicts varying degrees of damage to the intestinal tissues of . Salinity stress enhances the species diversity of intestinal flora in . Eight phyla of bacteria are detected in the intestine of . Dominant phyla include Proteobacteria, Firmicutes, and Actinobacteria. Furthermore, functional prediction reveals that acute salinity stress can significantly modify the abundance of pathways associated with nutrient and energy metabolism mediated by the intestinal flora of . These results indicate that acute salinity stress induces pathological damage to the intestinal tissues of , compromising the microbial habitat and leading to alterations in the intestinal flora composition. Additionally, can mitigate salinity stress by adjusting the composition of its intestinal flora and the corresponding functional pathways.
本研究聚焦于在20‰和40‰盐度水平下进行应激实验。分析了盐度应激下[具体对象]的肠道组织学变化及肠道菌群的结构特征。结果表明，急性盐度应激对[具体对象]的肠道组织造成不同程度的损伤。盐度应激提高了[具体对象]肠道菌群的物种多样性。在[具体对象]的肠道中检测到八个细菌门类。优势门类包括变形菌门、厚壁菌门和放线菌门。此外，功能预测显示，急性盐度应激可显著改变由[具体对象]肠道菌群介导的与营养和能量代谢相关途径的丰度。这些结果表明，急性盐度应激诱导[具体对象]肠道组织发生病理损伤，破坏微生物栖息地并导致肠道菌群组成改变。此外，[具体对象]可通过调节其肠道菌群组成及相应功能途径来减轻盐度应激。
