青海省海南州藏系绵羊鼠疫血清流行病学调查

Epidemiological investigation on plague serum of Tibetan sheep in Qinghai Hainan Prefecture

目的了解海南州藏系绵羊鼠疫流行情况,为鼠疫的预防预警提供理论依据。方法采集藏系绵羊(以下简称为藏羊)血清,应用鼠疫间接血凝(Indirect hemagglutination test,IHA)和鼠疫胶体金(gold immunochromatography assay,GICA)两种方法分别检测藏羊血清鼠疫FI抗体。结果对2016年采集自海南州的1 734份藏羊血清进行检测,共检出阳性血清28份,两种方法的相符率为100.00%,其中鼠疫F1抗体滴度1∶20的16份、1∶40的9份、1∶80的3份。结论海南州存在藏羊鼠疫流行,特别是在海南州兴海县,应加强藏羊鼠疫的监测。
