影响细粒棘球绦虫病传播动力学的因素分析

细粒棘球绦虫的生活史包括两种宿主和一个自由牛存的卵期,其传播动力学取决于细粒棘球绦虫、两种宿主、生态环境等三者的相互作用,主要包括细粒棘球绦虫的生物潜能、聚集性,宿主的免疫激活能力,虫卵的散播、分布、活力,环境温度、湿度、地理景观,肉类检疫、死亡动物及其内脏处理、犬驱虫和流浪宿主处理,人群生活卫生习惯和生产方式等.了解它们的相互关系及其对传播动态的影响,对制定和评价防治措施至关重要.该文重点就细粒棘球绦虫的生物因素、两种宿主、生态环境和防治手段埘其传播动力学的影响进行讨论.

Analysis on the transmission dynamic factors of echinococcosis granulosus

Life cycle of Echinococcus granulosus includes definitive hosts,intermediate hosts and a free egg stage.Its transmission dynamics depends on Echinococcus granulosus,the two hosts,the ecological environ-ment and their interactions,including biological potential of Echinococctu granulosus,aggregation,activation of host immune capability,the eggs spread,distribution and activity,environmental temperature,humidity and geographical landscape,quarantine for meat,dealing with the dead animals and their internal organs,helmin-thicide for dogs,life styles and habits of the crowd.h is essential for development and evaluation of control measures to understand their mutual relations and the influence Oil transmission dynamics.This review mainly focused Oil biological factors ofEchinococcus granulosus,the two hosts,the ecological environment and means of prevention and treatment.
