陕西省姜片吸虫病疫源地宿主动物的研究(Ⅰ)家畜和野生动物宿主

在陕西省汉中地区进行了姜片吸虫病家畜的自然感染调查(主要是家猪的粪检和剖检),家畜(包括猪、家兔、_家犬、驴、山羊、家猫、家鸭等)的人工感染试验以及野生动物(一包括野兔、灌、野猫、狐、野猪和糜鹿)的自然感染初步调查。工作结果认为本地区姜片吸虫的主要宿主动物是家猪。野生动物检查数目太少,不能逮下结论,但鉴于家兔人工感染易于成功,野兔是否有可能得到自然感染不能除外。作为陕西省姜片吸虫病疫源地要素之一(宿主动物)亦即疫源地的性质或类型问题,尚待了解本地区姜片吸虫病的人体感染情况后方能决定。进行了猪体姜片吸虫病的流行过程特点的调查,包括流行强度、年龄差别性、品种及性别差别性和季节性,给疫源地特点和疫病防治措施提供基础。本工作结合进行了对姜片吸虫成虫在猪体发育的初步观察。作为另文发表的病原研究的一个补充。

STUDIES ON THE HOST ANIMALS OF THE SHANSI FASCIOLOPSASIS NIDUS (Ⅰ) DOMESTIC AND WILD HOST ANIMALS

At Hangchung district, Shansi province, a survey was made on Fasciolopsis buski of the naturally infected domestic animals including swine, rabbits, dogs, donkey, goats, cats and ducks, the fecal and the post-mortem examinations of domestic swine being the chief aspect. Some wild animals containing 20 wild rabbits(Lepus sP.), 8 badgers(Meles meles Linnaeus, 1758), 3 wild cats(Felis sp.) 2 wolves(Vulpes vulpes Linneaus, 1758), I wild pig (Sus-scrofa Linnaeus, 1758) and I Daid's deer(Cervus alces Linna- eus, 1758) were autopsied and searched for the intestinal flukes. Some artificial infective experiments were also carried out with domestic animals. Studies presented in this article convinced us, at least for the time being that the most important host amimals of Fasciolopsis buski in this district are domestic hogs. The wild animls examined were too few to draw any conclusion on their infectivity to Fasciolopsis buski. The infection of the fluke in wild rabbits (Lepus sp.) can hardly be ruled out because it was found that the domestic rabbit was very susceptible through artificial infections. The present study concerns one of the elements of the Shansi Fasciolopsiasis nidus, i.e.the host animals. The complete knowledge awaits the information about whether human beings in this nidus are naturally infected. The nature of the nidus, or in other words the structure of its biocoenosis, can then be properly clarified
