中国云南洱海周边地带斯氏家鼠体表寄生虫的研究

目的 研究斯氏家鼠体表寄生虫的主要种类. 方法用U榆验和相关分析的统计方法对2003-2004 年云南洱海(中国滇西北著名的淡水湖泊) 周边88只斯氏家鼠体表寄生虫进行了调查,对斯氏家鼠的体表寄生虫群落和体表寄生虫医学和兽医学的重要性进行描述. 结果有70只斯氏家鼠寄生有体表寄生虫,侵染率为80%.采集到的体表寄生虫有54种,包括34种恙螨、15种革螨、4种蚤和1种吸虱.其中11种以前已经被证明是人类疾病的主要媒介. 结论斯氏家鼠很可能成为鼠疫、流行性出血热和恙虫病等病原体的贮存宿主.

Ectoparasites of Rattus steini in areas surrounding Erhai Lake in Yunnan Province,China

Objective To enrich eetoparasites research of Rattus steini.Methods Eetoparasites of 88 Ratttas steini (Rattus rattus sladeni Linnaeus,1758) were studied in areas surrounding Erhai Lake in Dali,Yunnan from 2003 to 2004 using Mann-Whitney U-test and Spearman correlation analysis,where was located in the wild rodent-type plague focus,one of 11 known plague foci in China and also an important focus of both tsutsugamushi disease and epidemic haemorrhagie fever (EHF).Here,the ectoparasite communities of Rattus steini and the potential medical and veterinary importance of these ectoparasites were described.Results A high proportion (80%) of 70 mice was found to be infected with ectoparasites.A total of 54 species of ectoparasites,including 34 species of chigger mite,15 species of mesostigmatid (gamasid) mite,4 species of flea and 1 species of sucking louse were collected.Within this ectoparasite complex.11 species have previously been reported to be vectors of human disease.Conclusion Rattus steini would appear to be a natural reservoir for pathogen of plague bacilli,tsutsugamushi disease and epidemic haemorrhagic fever (Korean haemorrhagic fever) viruses.
