目的通过分析2014—2015年长白口岸鼠类监测结果,掌握长白口岸地区鼠类的种类构成和携带汉坦病毒的情况,为进一步制定肾综合症出血热防控措施提供科学依据。方法 2014年5月—2015年4月,在吉林省长白口岸地区,以夹夜法捕鼠,取鼠血、肺、肝、肾、脾脏组织。采集样本送中国检验检疫科学研究院做汉坦病毒抗原检测。结果在吉林长白口岸地区共捕获鼠类96只,经分类鉴定隶属于1目2科4属6种,其中大林姬鼠、黑线姬鼠、褐家鼠为3个不同生境的优势鼠种;检蚤68只,染蚤率34.38%,蚤指数为0.71;检螨219只,鼠体染螨率56.25%,总染螨指数为2.28。获得有效鼠类内脏样本96份,检出汉坦病毒阳性10份,阳性率为10.42%。结论应进一步加强长白口岸地区鼠类防治和肾综合征出血热监测,防止肾综合征出血热的传播和流行。
OBJECTIVE: To provide a scientific basis for the further development of prevention and control measures of hemorrhagic fever with renal syndrome by analyzing the results of rodents monitoring in Changbai Port during 2014-2015 and grasping the species composition and carrying of hantavirus in rats in Changbai Port. Methods From May 2014 to April 2015, mice were caught in the night of Changbai Port in Jilin Province by blood-clotting method. Blood samples were collected from rats for blood, lung, liver, kidney and spleen. Samples were collected and sent to China Academy of Inspection and Quarantine for detection of Hantavirus antigen. Results A total of 96 rodents were captured in Changbai Port, Jilin Province. Six species (1 gene, 2 families and 4 genera) belonging to 1 orders, 2 families and 4 species were identified. Among them, Apodemus agrarius, Apodemus agrarius and Rattus norvegicus were the dominant species in three different habitats. 68 fleas were seized, the flea flea rate was 34.38%, flea index was 0.71; 219 mites were seized, the rate of dyed mites was 56.25%, and the total stained mite index was 2.28. 96 validated murine visceral samples were obtained, 10 were positive for Hantavirus, the positive rate was 10.42%. Conclusion The prevention and control of hemorrhagic fever with rodent syndrome and renal syndrome in Changbai Port should be further strengthened to prevent the spread and epidemic of hemorrhagic fever with renal syndrome.
