An earlier report that there is a high incidence (50 to 60 per cent) of cytotoxic antilymphocyte antibody in the sera of parous ewes is confirmed. This antibody is directed against paternally inherited antigens of the fetus. Antibody could be detected pre partum in four out of 34 primiparous ewes. However, there was no strong association between parity and the incidence of antibody. Antibody was also found in three out of 10 older rams which implies that pregnancy is not the only stimulus for antibody production.
一份较早的报告证实，经产母羊血清中细胞毒性抗淋巴细胞抗体的发生率很高（50%至60%）。这种抗体针对胎儿父系遗传的抗原。在34只初产母羊中，有4只在产前就能检测到抗体。然而，产次与抗体发生率之间没有很强的关联。在10只成年公羊中，也有3只检测到抗体，这意味着怀孕并非产生抗体的唯一刺激因素。
