摘要: 利用间接血凝试验对来自河南省部分地区未接种过传染性胸膜肺炎疫苗的部分规模化猪场的807份血清样品进行了传染性胸膜肺炎的抗体检测,以抗体效价≥1∶8为阳性作为判定标准,结果发现被检样品的总阳性率为30.11%(243/807),经产母猪、40日龄断奶仔猪、90~120日龄猪和160~180日龄猪的阳性率分别为56.94%(123/216)、9.04%(17/188)、27.65%(60/217)、23.12%(43/186),上述各阶段阳性猪抗体效价的几何平均数分别为1∶65.15、1∶11.53、1∶26.92、1∶19.73。

Abstract: By using indirect hemagglutination assay (IHA),807 nonvaccinated serum samples collected from partial intensive pig farms of Henan area were tested for antibody against PCP. The results were as follow: 30.11%(243/807) checked sera antibody titers were ≥1∶8 which was regarded as positive.The positive rates in sows,postweaning piglets(40-day-old),growing pigs(80 to 100-day-old),growing pigs(150 to 180-day-old) were 56.94%(123/216),9.04%(17/188),27.65%(60/217) and 23.12%(43/186), respectively. The geometrical average value of antibody titers of positive pigs were 1∶65.15, 1∶11.53, 1∶26.92, 1∶19.73 respectively.
