摘要:

目的 了解河北省肾综合征出血热(HFRS)国家级监测点宿主动物的构成、分布及携带汉坦病毒状况,为HFRS的防制提供科学依据。方法 在全省4个国家级监测点,分别于春季、秋季开展宿主动物调查,采用夹夜法调查鼠密度,免疫荧光法检测鼠肺病毒抗原。结果 2005-2009年监测点居民区鼠密度波动在0.63%~2.50%之间,野外鼠密度波动在0.37%~0.71%之间,居民区鼠密度高于野外(χ2=177.05,P<0.01);鼠带病毒率居民区为1.76%,野外为0.84%;鼠种构成以褐家鼠为优势鼠种(77.39%),其次为大仓鼠(12.42%)和小家鼠(8.70%);12份阳性鼠肺中,褐家鼠占83.33%(10/12),小家鼠和大仓鼠各占8.33%(1/12)。结论 褐家鼠是河北省HFRS的主要宿主动物和传染源,在HFRS的传播中起到重要作用;鼠密度和鼠带病毒率均较低,预示河北省HFRS不会出现大的流行。

Abstract:

Objective To get an insight into the composition, distribution and HV-carrying condition of host animals in the national monitoring sites of hemorrhagic fever with renal syndrome (HFRS) in Hebei province, providing scientific evidence for the prevention and control of the epidemic. Methods Investigations of host animals were carried out in spring and autumn, respectively, in the four national monitoring sites, with the trap-night method used for the detection of the density of rats and immunofluorescence technique for that of the pulmonary virus antigen of the pests. Results It was found that from 2005 to 2009 the density of rats in the populated area in the monitoring sites fluctuated between 0.63% and 2.50%, and the density of rats in the open country between 0.37% to 0.71%, with a higher density of the pests in the populated area than in the open country (χ2=177.05, P<0.01). The virus-carrying rate of rats in the populated area was 1.76% with the rate being 0.84% in the field. In terms of the composition of the host animals, Rattus norvegicus was the dominant host (77.39%), followed by Tscherskia triton (12.42%) and Mus musculus (8.70%). In the 12 positive rodents, 10 were R. norvegicus (83.33%), 1 was M. musculus (8.33%), 1 was T. triton(8.33%). Conclusion R. norvegicus is the main host animal and source of infection in Hebei province, playing an important role in the transmission of HFRS. Both the density of rats and the Hantavirus-carrying rate were low, indicating that it is less likely for HFRS to have an outbreak in Hebei province.
