褐家鼠Rattus norvegicus可能是云南省部分鼠疫流行区的储存宿主之一,其体表的某些寄生虫种类可能是人类疾病的传播媒介.为了解洱海周边地带褐家鼠的体表寄生虫群落,并对其医学和兽医学的重要性进行描述.用U检验和相关分析的统计方法对2003-2004年采自云南洱海(中国滇西北著名的淡水湖泊)周边地区的431头褐家鼠的体表寄生虫群落进行了研究.用构成比(C),侵染率(P)和平均丰富度(A)反映体表寄生虫的流行和密度状况.调查点位于我国11大鼠疫自然疫源地之一,此地也是我国恙虫病和流行性出血热的流行地区.结果表明:431头褐家鼠中307头寄生有体表寄生虫,侵染率为71%.采集到的体表寄生虫有47种,包括23种恙螨、16种革螨、6种蚤和2种吸虱,其中16种以前已经被证明是人类疾病的媒介.结果提示褐家鼠的体表寄生虫物种多样性高.

Rattus norvegicus may be as the reservoir host of plague in some domestic plague foci of Yunnan province,and some of its ectoparasite species may be the potential vectors of human diseases.To understand the ectoparasite communities in a population of R.norvegicus in the surrounding areas of Erhai Lake and the potential medical and veterinary importance of these ectoparasites are described.Ectoparasite communities of 431 rats of R.norvegicus were studied by using Mann-Whitney U-tests and Spearman correlation analysis,which were sampled in the sirrunding areas of Erhai Lake(a famous fresh water lake in Southwestern China) in Yunnan in 2003 to 2004.The constituent ratio(C),prevalence(P)and average ectoparasite abundance(A) were used to test prevalence and density of ectoparasites.The surveyed areas were located in the wild rodent.type plague focus,one of the 11 known plague foci in China and also an important focus of both scrub typhusand epidemic hemorrhagic fever(EHF).The results indicated that a high proportion(71%,307 individuals)of the sampled 431 rats was found to be infested with ectoparasites.A total of 47 ectoparasite species,including 23 species of chigger mites,16 species of mesostigmatid (gamasid) mites,6 species of fleas and 2 species of sucking lice were collected from R.norvegicus.Within this ectoparasite complex,16 species had previously been reported to be vectors of human disease agents.The results suggest that there is very high species diversity of ectoparasites of R.norvegicus.
