目的了解湛江地区鼠形动物种群中汉坦病毒的自然感染情况,为肾综合症出血热针对性的预防和控制提供科学依据。方法用笼夜法在湛江地区捕鼠,捕获的鼠形动物首先进行分类鉴定,然后解剖和股动脉采血,分离血清采用ELISA法检测HFRSIgM抗体。结果在本地区共捕获鼠形动物379只2目2科4属7种。家鼠以褐家鼠为优势鼠种,野鼠以黄毛鼠为优势鼠种。其中不同鼠形动物自然感染率板齿鼠为4.26%,黄毛鼠为3.60%,黄胸鼠为3.57%,褐家鼠为0.90%;其他鼠形动物小家鼠、屋顶鼠、臭鼩鼱感染率均为0。结论湛江地区鼠类自然汉坦病毒感染率较高,存在家鼠和野鼠两型为宿主的汉坦病毒感染。
Objective To understand the natural infection of Hantaviruses in the population of rodent animals in Zhanjiang and provide a scientific basis for the targeted prevention and control of hemorrhagic fever with renal syndrome. Methods Mouse cage was captured in Zhanjiang area by cage night method. The captured rat was first identified by classification. Then, the blood samples were collected from the dissected and femoral arteries and the serum was separated for detection of HFRSIgM by ELISA. Results A total of 379 species, 2 orders, 2 families, 4 genera and 7 species, were captured in this area. Rattus norvegicus is the dominant species of rodents in domestic mice, while Rattus rat is the predominant rodent species. Among them, the natural infection rate of different mouse-shaped animals was 4.26%, ramus was 3.60%, Rattus flavipectus was 3.57%, Rattus norvegicus was 0.90%; other mouse-shaped house mouse, roof mouse, stinkbug The infection rate is 0. Conclusion The prevalence of Hantaviruses in mice in Zhanjiang area is high, and Hantavirus infection is mainly caused by the two types of house mouse and vole.
