Zoonoses endanger human and animal seriously, which has aroused people . A lot of animal parasite diseases can infect person, so it is very necessary to study parasitic host and spread channel. As a kind of small mammal, rodent′s biological mechanism and ecological habits have lots of similarities with mankind, and also have very close relation with human beings. They are also store-host and infective source of some parasites of human body as Leishmania ,Toxoplasma ,Capillaria hepatica etc. So there is important connotation to study endoparasite of rodents. In domestic and international ectoparasite investigation and study, peoples have made a lot of work in the aspect of distribution and classfication. And concerning the research of endoparasite of rodents, especially in vole, it is lack for research information of endoparasite , whereas concerning the research of ecological feature of rodent endoparasite in inland desert area, it is very rare to study for person. From April 2004 to October 2004 ,we made a study for rodent endoparasite to use trap-captured in Tarim Basin and neighboring area , in two ecological station sites of Zunger ,in steppe of Mulei,in Bole mountains .The samples of 995 which belong to 10 family 21 genus 28 species was checked, including 963 rodents which belong to 4 family 15 genus 21 kinds, 127 rodents which belong 16 kinds are positive, potive rate is 13.19% ; Still including other 22 specimans which belong to 3 family 3 genus 4 kinds of beasts ( Crocidura leucodon ,Lepus yarkandensis, Mustela erminca and Mustela oversmanni ), 2 specimans are positive, including 10 birds which belong to 3 family 3 genus 3 kinds ( Oenanthe, Passer domesticus , Upupa epops), none is positive. A total of 129 endoparasites are found, its total positive rate is 12.96%. And total find 17 kinds of nematode , 1 kind of Acanthocephal, 15 kinds of cestode, A total of endoparasite is 34 kinds, through investigation and study for its district, epidemic desease and ecologic ,the results show as follows : 1、The distribution of parasite has area specificity and host specificity ; 2、Influence rate of endoparasite is concerned with age of host, kind of host, distribution of host , season , but it is unconcerned with sex . 3、Parasite disease has the tendency from original desert rodents to artificial forest, to farmland and resident district rodents , and then spread to person ; 4、Parasite can influence host’s growth, evolution and propagate , reducing growth rate through reducing degree of grossness , reducing birthrate through decreasing the numbers of embryo,consequently regulates the number of population ; 5、Similarities of parasite community is relation to relative of the host, geographic environment that the host locate in,the community of the host ; 6、Niche′s research result shows that the most parasite has only a single host, its peculiarities is more strong , But partial parasites have many hosts , its peculiarities is lower, is easily spread between different hosts, dangerousness is also greater.
