摘　　要：为了调查外省市调入东莞的临宰生猪口蹄疫抗体水平,2004年、2006年11月～12月、2007年2月～3月、2007年3月～4月共4个阶段,对调入东莞市的临宰生猪进行随机抽血采样,共2800份。第1阶段用ELISA方法检测,第2～4阶段用O型口蹄疫正向间接血凝试验检测抗体。结果表明,2004年抽样合格率仅为13.7%,2006年11月～2007年4月,临宰生猪免疫抗体高于1∶32的占29.77%,高于1∶128的只占9.66%,调查结果表明,调入东莞市的临宰生猪口蹄疫抗体水平普遍偏低,需加强生猪上市前口蹄疫的免疫。The objective of this pepar is to investigate and study FMD antibody level of slaughtered pigs transported from foreign provinces. 2800 serum samples were got in Dongguan during the four stages of 2004, November 2006 to December 2006,February 2007 to March 2007 and March 2007 to April 2007, the samples of 2004 were detected by ELISA, the others were detected by FMDV type O positive hemagglutination. The qualified rate is only 13.7 % in 2004, antibody level above 1 ： 32 is 29.77%, while above 1 ： 128 only accounts for 9. 66% in November 2006 to April 2007. The results show that FMD antibody level is low.
