摘要

这项工作试验的目的是确定螺旋藻和迷迭香在实验感染前对尼罗罗非鱼性能的真正影响。此外，还包括这些处理在感染嗜水单胞菌（A. hydrophila）前后对肝肾功能、某些器官的组织学以及肝组织中某些抗氧化和免疫相关基因表达的影响。为此，我们配制了四种日粮：第一种日粮不含任何添加剂，作为对照组（Con）；第二种日粮含有螺旋藻（SP），每公斤日粮 7.5 克；第三种日粮含有迷迭香（RM），每公斤日粮 10 克；第四种日粮含有迷迭香和螺旋藻，作为 SP + RM 组。不同参数的检测结果表明，与对照组相比，迷迭香和螺旋藻单独或混合使用均有促进生长的作用（P ≤ 0.05），混合使用的效果更好。此外，感染前后的血液学指标、免疫学检测、吞噬细胞活性和指数、抗氧化和免疫相关基因的表达均有所改善。此外，螺旋藻和迷迭香在感染前对不同器官无病变，感染后病变减少，具有积极作用。

Immunomodulatory and growth promotors effects of rosemary (Rosmarinus officinalis) and/or Spirulina with respect to some gene expression on Nile tilapia (Oreochromis niloticus) in Aswan Governorate

The purpose of this work trial was to determine the true impact of spirulina and rosemary in a combination treatment on Nile tilapia performance before experimental infection. Moreover, the effects of these treatments on the liver and kidney functions, the histology of certain organs, and the expression of certain antioxidant and immune-related genes in the liver tissue both before and after Aeromonas hydrophila (A. hydrophila) infection are also included. To achieve this purpose, four diets were prepared: the first was free of additives as a control group (Con), the second contained (SP) spirulina at 7.5 g/kg of diet, the third contained (RM) rosemary at a rate of 10 g/kg of diet, and the fourth one contained rosemary and spirulina as a SP + RM group. The results of the different parameters indicated the growth-stimulant effects of rosemary and spirulina either alone or in a combination when compared with the control group (P ≤ 0.05), with a superior effect to combination treatment. In addition, improved hematological parameters, immunological assays, phagocytic activity and index, and expression of antioxidant and immune-related genes occurred before and after infection. Moreover, there were positive effects of spirulina and rosemary without pathological lesions in the different organs before infection and fewer lesions after infection.

期刊介绍： Aquaculture is an international journal for the exploration, improvement and management of all freshwater and marine food resources. It publishes novel and innovative research of world-wide interest on farming of aquatic organisms, which includes finfish, mollusks, crustaceans and aquatic plants for human consumption. Research on ornamentals is not a focus of the Journal. Aquaculture only publishes papers with a clear relevance to improving aquaculture practices or a potential application.
