目的了解南沙口岸鼠形动物携带汉坦病毒(HV)情况,为制定防制措施提供依据。方法 2013年5月至2014年4月采用笼捕法和夹夜法捕获南沙口岸鼠形动物,采用实时荧光PCR检测鼠肺。结果共捕获鼠形动物538只,隶属于2科6种,分别为臭鼩鼱、褐家鼠、黄胸鼠、板齿鼠、小家鼠和黄毛鼠,其中臭鼩鼱为优势种,占捕获总数的53.16%(286/538);共采集鼠肺538份,HV阳性率为2.60%(14/538),基因型均为汉城型HV。结论南沙口岸鼠形动物携带HV,存在鼠形动物传播肾综合征出血热的风险,应加强监测和病原学检测,采取防制措施。
Objective To understand the situation of hantavirus (HV) carried by rodent animals in Nansha Port, and provide the basis for the establishment of control measures. Methods From May 2013 to April 2014, the rats of the Nansha port were captured by cage catching and catching the night, and the murine lungs were detected by real-time fluorescence PCR. Results A total of 538 murine animals were captured, belonging to 2 families and 6 species, respectively, stinkbug, Rattus norvegicus, Rattus flavipectus, Brachiaria, Mus musculus and Rattus rat, of which the stinkbug is the dominant species, Accounting for 53.16% (286/538) of the total catches. A total of 538 rat lungs were collected. The positive rate of HV was 2.60% (14/538). All the genotypes were Seoul HV. Conclusion There is a risk of rat-type animals carrying HV in Nansha port. There is a risk of hemorrhagic fever with renal syndrome in rats. Therefore, monitoring and etiological testing should be strengthened and preventive measures should be taken.
