摘要
小瓜虫是淡水养殖中致死率最高的寄生原虫之一,本文首先分析了小瓜虫病的发病症状,并简述了该病的发现、流行及分布状况,从其起源到地方流行及全世界性蔓延情况入手,总体分析了小瓜虫病的流行原因及危害。在小瓜虫病的防治方面,依次从物理方法、化学方法和生物疫苗治疗三个方面入手,重点分析了这三种方法的利弊,通过比较,作者认为基因工程疫苗防治小瓜虫病逐步成为研究热点,具有广阔的发展空间,在继续加大力度筛选无公害有效药物的同时,应大力开展基因工程疫苗研究,防治一体。尽量降低其对食用鱼和观赏鱼养殖的危害,力争彻底治愈小瓜虫病。
Ichthyophthiriasis if one of the highest fatality rate in freshwater aquaculture.In this paper ,the symptoms of Ichthyophthiriasis firstly is analyzed ,and the discovery is Outlines ,from its origins to the local epidemic and the world of the situation began to spread;it analyzed Ichthyophthiriasis popular causes and haz-ards.In the prevention and treatment of Ichthyophthiriasis ,three aspects in turn from the physical treatment methods,chemical and biological vaccines,analyzes the advantages and disadvantages of these three methods. By comparison,Th genetically engineered vaccine-preventable Ichthyophthiriasis gradually become a hot top-ic,has a broad space for development,Should be pollution-free drug screening and vaccine research at the same time.Strive to completely cure Ichthyophthiriasis.
