本文提出了将贾第鞭毛虫病作为一种再现的传染性疾病的理由,特别是叙及在儿童保健中心,家畜和宠物中的贾第鞭毛虫感染,在人畜共患病传播中的作用以及控制的困难。由于能感染哺乳动物,贾第鞭毛虫种的基因型和表现型的变异性较大。导致至今尚未确定宿主特异性并解决人畜共患传播的问题。最近基于PCR的分子鉴定方法的应用已经对贾第鞭毛虫种群的遗传结构有了较多的了解,本文对贾第鞭毛虫感染的人畜共患病的传播和分子流行病学进行了综述。 This article presents the rationale for the use of giardiasis as a reproductive infectious disease, in particular addressing the role of giardiasis in child health centers, livestock and pets, in zoonotic transmission, and Control difficulties. Due to their ability to infect mammals, genotypes and phenotypes of Giardian species are more variable. This has led to the problem of not determining the specificity of the host and solving the zoonotic spread so far. The recent application of PCR-based molecular identification methods has gained a greater understanding of the genetic structure of the Giardian population and the zoonotic spread and molecular epidemiology of Giardia infections are reviewed.
