Abstract:

Objective To investigate Hantavirus(HV) infection of captured rodents at Nansha ports and provide a scientific basis for the control of rodents and rodent-borne diseases. Methods During May 2013 to April 2014, surveillance of the rodent carriers was performed in 7 coastal harbors in Nansha. The rodents were collected using rat cages and clamps. Lung samples were taken for HFRS viral testing. HV genotype was analyzed using Real-time RT-PCR. Results A total of 538 rodents were captured, including 6 species Suncus murinus, Rattus norvegicus, R. tanezumi, Bandicota indica, Mus musculus, R. losea, among which S. murinus was the predominant group, accounting for 53.16% (286/538). Total of 538 samples were tested, the positive rate of HV was 2.60%(14/538). Nucleotide sequences analysis showed that the virus detected belongs to the Seoulvirus type. Conclusion The HV was carried by rodents at Nansha ports. Surveillance for hemorrhagic fever with renal syndrome among rodents and the control of rodents should be implemented.

摘要:

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。
