The present study was conducted on Cyprinus carpio var. communis challenged with Aeromonas hydrophila. The objective of the study was to assess the alteration in various haematological parameters, biochemical parameters and haematopoietic organs of the challenged fish post challenge on the four time points (1^st, 3^rd, 7^th and 10^th day). The results obtained showed considerable difference when compared with the standard values of the control which was run parallel to the experimental study. The assessed haematological parameters including the haemoglobin values (mean ± standard deviation) of the challenged fish assessed at the end of the experimental study were found to be lower (2.17 ± 0.52) when compared with the control (3.73 ± 0.28). Similarly, the values for TLC, neutrophils, monocytes, eosinophils and basophils obtained were greater while as for lymphocytes the values obtained at the end of the experimental study were lower when compared with the control. The values for various blood biochemical parameters as total protein, albumin and globulin were lower while as for bilirubin, triglycerides and glucose the values obtained at the end of the experimental study were greater when compared with the control. The values were statistically analysed (p ≤ 0.05) and found significant, concluding that A. hydrophila is a potential threat to the growing aquaculture sector and can have adverse impact on the health of Cyprinus carpio while raising them in the culture conditions.

Cyprinus carpio var. 血液生化参数和造血器官的免疫发病机制。共生体受到嗜水气单胞菌的挑战

本研究是在Cyprinus carpio var.上进行的。共生体受到嗜水气单胞菌的挑战。这项研究的目的是评估各种血液参数，生化指标和在四个时间点（1受到质疑的鱼攻击后的造血器官变化^ST，3^次，7^次和10^次日）。与平行于实验研究的对照的标准值相比，所获得的结果显示出相当大的差异。与对照 (3.73 ± 0.28) 相比，在实验研究结束时评估的受攻击鱼的血红蛋白值 (平均值 ± 标准偏差) 等血液学参数较低 (2.17 ± 0.52)。类似地，与对照相比，获得的 TLC、中性粒细胞、单核细胞、嗜酸性粒细胞和嗜碱性粒细胞的值较大，而淋巴细胞在实验研究结束时获得的值较低。各种血液生化参数如总蛋白、白蛋白和球蛋白的值较低，而胆红素、与对照相比，在实验研究结束时获得的甘油三酯和葡萄糖值更高。对数值进行统计分析（p  ≤ 0.05) 并发现显着，得出结论A . 嗜水是对不断增长的水产养殖部门的潜在威胁，在养殖条件下饲养它们的同时，会对鲤鱼的健康产生不利影响。
