目的掌握大榭口岸鼠形动物种群构成及携带病原体情况。方法以鼠夹(夹夜法)和鼠笼捕捉鼠形动物,用直接免疫荧光法(DIF)、间接免疫荧光法(IIF)和间接血球凝集试验(IHA)分别进行肾综合征出血热(HFRS)抗原、抗体和鼠疫 F1抗体检测;按国标 GB4798.4-2003进行鼠伤寒沙门氏菌检测。结果捕获鼠130只,分别隶属2目2科4属7种。鼠密度全年平均为0.44%,鼠密度最高为6月,密度为1.63%。臭鼩和褐家鼠为优势种群。肾综合征出血热抗原阳性率为1.54%,抗体阳性率8.69%,鼠疫 F1抗体监测全部阴性,鼠伤寒沙门氏菌感染率为2.60%。结论初步掌握了大榭口岸鼠形动物种群构成以及肾综合征出血热、鼠疫和鼠伤寒沙门氏菌携带情况,为加强鼠形动物监测及控制工作提供依据。
Objective To understand the population structure and pathogen of rat in Daxie Port. Methods Rat-shaped animals were captured by the mouse clamp and the squirrel cage. Direct immunofluorescence (DIF), indirect immunofluorescence (IIF) and indirect hemagglutination test (IHA) were used to detect hemorrhagic fever with renal syndrome (HFRS ) Antigens, antibodies and plague F1 antibody test; according to national standard GB4798.4-2003 Salmonella typhimurium detection. Results 130 mice were captured, belonging to 2 orders, 2 families, 4 genera and 7 species. The average annual rat density was 0.44%, the rat density was highest in June, and the density was 1.63%. Stinkbugs and Rattus norvegicus are the dominant species. The positive rate of hemorrhagic fever with renal syndrome was 1.54% and the positive rate of antibody was 8.69%. The F1 antibody of plague was all negative. The infection rate of Salmonella typhimurium was 2.60%. Conclusion The population structure of rats in Daxie Port and the carrying of hemorrhagic fever with renal syndrome, plague and Salmonella typhimurium were preliminarily mastered, which provided the basis for the monitoring and control of rodent animals.
