颖上县肾综合征出血热储存宿主的调查

本文指出，用间接荧光技术从安徽省颖上县本病的地方性流行区所捕获的6种鼠中，査到4种鼠携带本病特异性抗原。其中黑线姬鼠534只，阳性鼠29只，带毒率为5.4%；褐家鼠132只，阳性鼠11只，带毒率为8.3%；小家鼠19只，阳性鼠1只，其带毒率为5.3%；大仓鼠433只，阳性鼠2只，其带毒率为0.5%，因此认为，在该农村型HFRS的流行区，其主要宿主为褐家鼠和黑线姬鼠。从而指出褐家鼠在引起农村型HFRS的流行方面，也具有重要意义。
另外，本文还用模式图，分析了该区各鼠种生活活动区间的关系，指出这些鼠种间的特定生态学联系，在本病的鼠间传播和病毒在自然界的循环中，可能具有重要作用。

Survev on the Principle Reservior for HFRS in Yingshang County, Anhui Province

6 species rodents caPtured from Yingshang county HFRS endemic area were tested with the indirect immunofluorescent technique.The results showed that the immunofluorescent antigen could be detected in the lungs of 4 species of rodents.Namely, positive rate of 534 Apodemus agrarius was 5.4%,that of 132 Rattus norvegicus was 8.3%,one of 19 Mus musclus mice was Positive (5.3%), two of 433 Cricetulus triton was positive (0.5%).It was thought that the principal reserviors for HFRS in the runal endemic area were Rattus norvegicus and Apodemus agrarius. Hence, Rattus norvegicus is also important in rural spread of HFRS.
On the other hand, the relationship of the biotopes for the different species of rodent was also analysed.It was showed that their ecological characteristic played an important role in the process of inter-species spread of the aetiological agent.
