目的 :了解肾综合征出血热宿主动物的数量、种群构成及带毒状况。方法 :采用夜夹法对野外和室内进行小兽密度和种群调查 ;同时取肺作带毒调查 ;取猫、兔、羊等家畜血 (滤纸法 )作感染率调查。结果 :2 2年野外小兽密度为 4.2 1%～ 2 6 .5 7% ,平均为 11.31% ;13年室内小兽密度为 2 .92 %～ 9.47% ,平均为 6 .94%。野外以黑线姬鼠为主 (5 4.2 0 % ) ,次为褐家鼠 (2 2 .5 6 % ) ;室内以褐家鼠和小家鼠为主 ,分别占 6 3.36 %和 2 8.6 4%。小兽带毒率黑线姬鼠 2 .98% ,褐家鼠 2 .2 2 % ,小家鼠 2 .6 3% ,大足鼠 5 0 % ,中麝鼠句 2 .38% ;猫感染率为 8.33%。结论 :黑线姬鼠和褐家鼠为开江县肾综合征出血热的主要宿主动物和传染源 ,猫在本病病原传播中起着重要作用
Objective: To understand the quantity, population composition and virulence of hemorrhagic fever with renal syndrome in host animals. Methods: Night clip method was used to investigate the density and population of small mammals in the field and the interior. At the same time, the lungs were taken for investigation of poisoning. The infection rates of cats, rabbits and sheep were determined by filter paper method. Results: The density of small mammals was 4.2 1% -2 26.57% in 2 years, with an average of 11.31%. The density of indoor animals was 2.92% ~ 9.47% in 13 years with an average of 6 .94%. In the wild, Apodemus agrarius was the dominant species (4.220%), followed by Rattus norvegicus (22.56%), while Rattus norvegicus and Mus musculus were dominant in the field, accounting for 6 3.36% and 2 8.64 %. Small animals with poisoning rate of Apodemus agkistrodon by 2.98%, Rattus norvegicus 2 .2 2%, Mus musculus 2 .63%, 50% of the large foot mouse, muskrat 2%; cat infection rate 8.33%. Conclusion: Apodemus agrarius and Rattus norvegicus are the main host animals and sources of infection of hemorrhagic fever with renal syndrome in Kaijiang County. Cats play an important role in the pathogenesis of this disease
