Abstract: Objective To investigate the importance of the indicator animals in plague surveillance by finding out the positivity rate against the F₁ antibody of plague in the plague focus. Methods IHA was used to test the F₁ antibody against plague in the blood serum of the indicator animals and rodents. Results The positivity rates of the F₁ antibody of the indicator animals and rodents were 2.06%(10/486) and 0.37%(1/272),respectively. The positivity rates were significantly different (χ²=4.18,P<0.05) between the indicator animals and rodents. Conclusion The indicator animals was important for the prevention and control of plague.

摘要： 目的 调查广西鼠疫疫区指示动物血清F1抗体阳性率,探讨鼠疫指示动物在鼠疫监测中的意义。方法 采用间接血凝试验法,检测鼠疫指示动物和鼠类血清中鼠疫F₁抗体。结果 鼠疫指示动物(猫和狗)血清F₁抗体阳性率为2.06%(10/486),鼠血清F₁抗体阳性率为0.37%(1/272),两者差异有统计学意义(χ²=4.18,P<0.05)。结论 鼠疫指示动物血清学监测对鼠疫防制具有非常重要的意义。
