目的调查吉林中朝边境口岸地区啮齿动物及其体表寄生虫的种类、构成和携带汉坦病毒的情况。方法 2009年至2011年,在吉林省长白口岸和朝鲜惠山口岸地区,以夹夜法捕鼠,梳刷法采集鼠体表寄生虫,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啮齿动物336只,隶属于1目2科6属9种,其中黑线姬鼠为优势鼠种,占捕鼠总数的67.26%;检蚤302匹,染蚤率为28.87%,蚤指数为0.90;检螨978只,染螨率为61.90%,螨指数为2.91;获得有效样本190份,检出汉坦病毒阳性7份,阳性率为3.68%。在朝鲜惠山口岸地区共捕获啮齿动物96只,隶属于1目3科4属5种,其中褐家鼠为优势鼠种,占捕鼠总数的79.17%;检蚤141匹,染蚤率为53.13%,蚤指数为1.47;检螨153只,染螨率为51.04%,螨指数为1.59;获得有效样本96份,检出汉坦病毒阳性10份,阳性率为10.42%。结论应进一步加强中朝边境长白口岸地区啮齿动物防治和鼠类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 investigate the species, constitution and carrying of Hantavirus in rodents and their surface parasites at the Sino-Korean border crossings in Jilin Province. Methods From 2009 to 2011, mice were collected at the Changbai Port of Jilin Province and the Huishan Port of North Korea by catching the night with a nocturnal method and the brushing method to collect parasites of the mouse body and take blood, lung, liver, kidney and spleen tissues. Samples were collected and sent to China Academy of Inspection and Quarantine for detection of Hantavirus antigen. Results A total of 336 rodents were captured in Changbai Port, Jilin Province, belonging to 9 families of 1 gene, 2 families and 6 genera, of which 9 species were dominant mice, accounting for 67.26% of the total number of catches; 302 fleas were detected, Of which 28.87%. The flea index was 0.90. Nine hundred and seventy mites were seized, the rate of stained mites was 61.90% and the index of mites was 2.91. Totally 190 valid samples were obtained, of which seven were positive for hantavirus. The positive rate was 3.68%. A total of 96 rodents were captured in Huishan Port of North Korea, belonging to 1 species, 3 families, 4 genera and 5 species, of which Rattus norvegicus was the dominant species, accounting for 79.17% of the total number of traps; 53.13%, flea index was 1.47; 153 mites were tested, the rate of stained mites was 51.04% and mite index was 1.59; 96 valid samples were obtained, of which 10 were positive for Hantavirus. The positive rate was 10.42%. Conclusion It is necessary to further strengthen the monitoring of rodent control and hemorrhagic fever with rodent syndrome in the Changbai Port border area between China and North Korea to prevent the spread and spread of hemorrhagic fever with renal syndrome.
