摘　　要：本试验对本校畜牧站提供的17只山羊关节炎脑炎(简称CAE)阴性奶山羊和7只CAE阳性奶山羊外周血液T细胞,利用E-玫瑰花环试验进行了测定,并且扑杀其中6只CAE阳性奶山羊,采集脾脏和CAE病毒(CAEV)易侵害的靶器官所属淋巴结进行了病理组织学观察。结果所见CAE阳性奶山羊外周血液T细胞数量较CAE阴性羊低,生物统计学检验,二者差异显著。脾脏和淋巴结中结缔组织大量增生,毛细血管充血,淋巴小结稀少,淋巴细胞轻度变性,坏死及萎缩。生发中心扩张,窦内有大量巨噬细胞、网状细胞、浆细胞及少量嗜中性白细胞和浆液、纤维素。还发现有大量淀粉样物质及含铁血黄素沉着。T cells of peripheral blood from CAE negative ,or CAE positive milk goats had been measured with E rosette test. The results revealed the T cell level in GAE positive goats WAS significantly, lower than that of CAE negative goats ( P<0.01 ) . The positive goats were dissected too, and pathological changes happening in the spleens and lymph nodes of tissues affected by CAE virus were observed.
