目的 明确疫区主要宿主动物及疫区性质 ,为制定防制策略提供科学依据。方法 采用间接免疫荧光技术检测肾综合征出血热 (HFRS)病毒抗原和抗体 ,小型宿主动物密度调查采用夹夜法。结果 宿主动物野外以黑线姬鼠 (Apodemus agrarius,Aa)为优势种 ,其密度和带毒率均最高 ;住宅区以褐家鼠 (Ratlus norvegicus,Rn)为优势种 ,褐家鼠在 2 0世纪 80年代中后期至 90年代初带毒率较高 ,之后未检出 HFRS病毒抗原。结论 贵州省遵义县肾综合征出血热疫区是以黑线姬鼠为主要宿主动物和传染源 ;2 0世纪 80年代中后期疫区性质以姬鼠型为主的混合型 ,其余年代均为典型的姬鼠型
Objective To identify the main host animals in the epidemic area and the nature of the epidemic area and provide a scientific basis for the formulation of control strategies. Methods Indirect immunofluorescence assay was used to detect HFRS virus antigens and antibodies in small intestine. Results The dominant species of Apodemus agrarius (Aa) was the host animal in the field, which had the highest density and virulence rate. In the residential area, Rattus norvegicus was the dominant species, In the late 1980s to the early 1990s, the carrier rate was high, and no HFRS virus antigens were detected thereafter. Conclusion The epidemic area of hemorrhagic fever with renal syndrome in Zunyi County, Guizhou Province, is characterized mainly by Apodemus agrarius as the main host animal and source of infection. In the late 1980s, the nature of the endemic areas was mainly of the Apodemus agkistrodon type, with the rest of the years being Typical Apodemus type
