Abstract

Background and aim: Horses used for antisera production are repeatedly hyperimmunized to produce high levels of specific antibodies. This prolonged process can lead to various health issues, including amyloidosis, which involves the accumulation of amyloid proteins in organs and tissues, potentially causing organ dysfunction and failure. These horses are often retired when they no longer produce adequate antibody levels. This study aimed to evaluate the impact of prolonged antisera production on the health of retired horses by examining their blood biochemistry and serum amyloid A (SAA) levels, which are indicators of systemic inflammation and organ damage.

Materials and methods: Blood samples were collected from 12 horses for this study. Nine horses were retired antisera-producing horses that had been discontinued for 2 years, while three healthy non-antisera-producing horses were used as controls. These twelve horses were divided into four groups based on the duration of their active period as antisera producers (never been used, 2-3 years, 4-5 years, and 6-7 years). We measured key blood biochemistry parameters and SAA levels to evaluate the health status of the horses.

Results: Total protein, fibrinogen, and globulin levels were elevated, whereas other parameters remained normal. The findings indicate that despite normal SAA levels, the horses exhibited signs of ongoing health issues related to their previous use in antisera production, such as increased total plasma protein, fibrinogen, and globulin levels, as well as the presence of amyloid deposits in vital organs such as the liver and kidneys, as observed in post-mortem examinations.

Conclusion: Despite normal SAA levels, retired antisera-producing horses showed elevated total protein, fibrinogen, and globulin levels, indicating ongoing health issues.

评估退役抗血清生产马的健康影响:血液生化和血清淀粉样蛋白 A 分析。
背景和目的:用于生产抗血清的马匹要反复进行过度免疫,以产生高水平的特异性抗体。这种长期的过程会导致各种健康问题,包括淀粉样变性,即淀粉样蛋白在器官和组织中积累,可能导致器官功能障碍和衰竭。当这些马匹不再产生足够的抗体水平时,它们通常会退役。本研究旨在通过检测退役马的血液生化指标和血清淀粉样蛋白A(SAA)水平,评估长期产生抗血清对退役马健康的影响:本研究采集了 12 匹马的血液样本。九匹马是停产两年的退役抗血清生产马,三匹健康的非抗血清生产马作为对照。这 12 匹马根据它们作为抗血清生产者的活跃期(从未使用过、2-3 年、4-5 年和 6-7 年)分为四组。我们测量了主要的血液生化指标和 SAA 水平,以评估马匹的健康状况:结果:总蛋白、纤维蛋白原和球蛋白水平升高,而其他参数保持正常。研究结果表明,尽管这些马的 SAA 水平正常,但它们仍表现出与以前用于生产抗血清有关的持续健康问题,如血浆总蛋白、纤维蛋白原和球蛋白水平升高,以及在肝脏和肾脏等重要器官中出现淀粉样沉积物,这些都是在死后检查中观察到的:结论:尽管SAA水平正常,但退役抗血清产生马的总蛋白、纤维蛋白原和球蛋白水平升高,表明健康问题仍在持续。
