摘要
动物疫苗是一种特殊的生物制品,疫苗在生产、运输和保存、使用过程中有着严格的技术要求。疫苗怕光照、怕热,光和热会造成某些活性蛋白变性、沉淀,导致疫苗质量下降,甚至会造成微生物失去活性,对免疫效果造成严重影响,构建完善的冷链体系是保证疫苗质量的关键。但在广大基层地区,疫苗冷链体系建设还存在诸多不合理的情况,疫苗在运输、保存、使用过程中,由于保存不当失去原有的免疫效价,造成免疫失败,动物存在严重的免疫空白,给多种传染性疾病的传播流程提供条件。因此需要充分认识到冷链体系建设在动物疫病防控中的重要作用,并结合具体的工作情况,加强疫苗冷链体系建设。该文主要分析冷链体系建设在动物疫病防控中的作用,论述具体的建设措施。
Animal vaccine is a kind of special biological product.It has strict technical requirements in the process of production,transportation,preservation and use.The vaccine is afraid of light and heat.Light and heat can cause the denaturation and precipitation of some active proteins,leading to the decrease of the quality of the vaccine and even the inactivation of microorganisms,which has a serious impact on the immune effect,constructing perfect cold chain system is the key to guarantee the quality of vaccine.However,there are still many unreasonable situations in the construction of vaccine cold chain system in the vast grass-roots areas.In the course of transportation,preservation and use of vaccines,due to improper preservation,the original immune potency is lost,resulting in immune failure,there is a serious immune gap in animals,which allows for the spread of multiple infectious disease.Therefore,it is necessary to fully recognize the important role of cold chain system construction in animal disease prevention and control,and to strengthen the construction of vaccine cold chain system.This paper mainly analyzes the role of cold chain system construction in animal disease prevention and control,and discusses the concrete construction measures.
