摘 要 目的 了解麻疹血凝抑制抗体样物质在猪群中的分布情况。方法 采用麻疹血凝抑制试验，并用白陶土法去除非特异性凝集素的干扰。结果 检测192份猪血标本，麻疹血凝抑制抗体阳性158份，阳性率82.29%，平均抗体滴度(GMT)1∶3.5，以1∶2～1∶4的低抗体为主(78.48%)。结论 在本地猪群血液中所检出的麻疹血凝抑制抗体样物质，并非由于猪感染与麻疹病毒有近缘关系的牛瘟病毒或犬瘟病毒而出现的一种交叉免疫反应，也不是非特异性凝集素的干扰，对猪感染麻疹病毒所致的可能性尚找不出理由排除。因此，有必要作进一步研究和探索，这对控制和消灭麻疹是一项很有意义的工作。

ABSTRACT Aim It was necessary toknow how the substance which is analogous to hemmagglutination inhibition antibody ofmorbilli distributed in the blood of swine.Methods It was done with thehemmagglutination inhibition test,and the non-specificity agglutinin was removed withKaolin method.Results Among 192 samples examined,there were 158 samplescontaining the morbillous antibody of hemmagglutinatin inhibition,and the positive ratewas 82.29%.The average antibody titer(GMT)was 1∶3.5 and it was mainly from1∶ 2 to 1∶4(78.48%).Conclusion It was believed thatthe substance,analogous to morbillous antibody of hemmagglutination inhibition,in theblood of swine in our area.It was neither the crossed immune respons,resulted from beinginfected with Rinderpest virus or Febris catarrhalis infectiosa canun virus which wereclosely relative to morbillous viruw,nor was interfered with by the non-specificityagglutinin and the there was the possibility that the production or the substance wasresulted from being infected with morbillous virus.There fore,the substance is worthfurther studying and discussing,and will be very important to control and eliminate morbilli.
