Abstract

Sera from inbred SPF White Leghorn chickens at 6 weeks or 19-22 months of age did not have anti-OA agglutinins as determined by the passive HA reaction; 2-day-old chicks also lacked the anti-OA activity. Inbred chickens kept in SPF isolators for 6 weeks, then transferred to a conventional environment for 7 weeks, produced anti-OA agglutinins. Inbred White Leghorn adult chickens conventionally reared had a high anti-OA agglutinin titer. It appeared that natural anti-OA agglutinin s are elaborated in response to environmental pathogens in certain lines of chickens. The titer in the individual chicken appeared as early as 10 weeks and was maintained until old age. The presence of natural anti-OA agglutinins did not prevent egg-laying but appears to have delayed it. The HA reaction is specific and can be absorbed.

摘要

通过被动血凝反应测定，6周龄或19 - 22月龄的近交SPF白来航鸡血清中没有抗OA凝集素；2日龄雏鸡也缺乏抗OA活性。在SPF隔离器中饲养6周，然后转移到常规环境中饲养7周的近交鸡产生了抗OA凝集素。常规饲养的近交白来航成年鸡具有较高的抗OA凝集素效价。似乎在某些品系的鸡中，天然抗OA凝集素是对环境病原体作出反应而产生的。个体鸡的效价早在10周龄时就出现，并一直维持到老年。天然抗OA凝集素的存在并不妨碍产蛋，但似乎会使其延迟。血凝反应具有特异性且可被吸收。
