无尾两栖类宿主与多盘科吸虫关系的初步探讨

The preliminary study of the relationship between anura host and polystoma(Monogenea)

文章调查研究了云南14种无尾两栖类体内寄生多盘吸虫的自然感染情况。滇中、滇东地区滇蛙和昭觉林蛙、滇南杜氏泛树蛙为多盘吸虫宿主。分析影响多盘吸虫宿主分布的原因可能有:地质构造、无尾两栖类宿主对多盘吸虫的免疫力和多盘吸虫侵入宿主产生的致病力对抗的不同。两栖类宿主和多盘吸虫的协同进化,导致同一种无尾两栖类宿主体内寄生的多盘吸虫有交叉感染情况存在。

In this article ,the author has researched the natural infectious-state of the Polystoma (Monogenea) parasitic in the urinary bladders of 14 species of Anura. Among the frogs the Rana pleuraden Boulenger and the R. chaochiaoensis Liu in the middle of Yunnan , in the northeast of Yunnan,and the Polypedates dugritei David in the South of Yunnan are the hosts of the Polystoma. We confered that the causes affecting the distribution of the host of Polystoma include the structure of the earth's crust , the temperature and the differences between the immunity of the Polystomatidae against the host of amphibians and the pathogenic force caused by Polystomatidae when it infects the host.It is co evolution of the host of amphibians and the Polystomatidae which results in the cross-infectious existence of the parasitic Polystomatidae in the urinary bladder of the same type Anura host.
