摘　　要：用常规病理学方法 ,对人工感染 2 .4× 10 5个混合球虫卵囊的雏鸡进行病理解剖学和病理组织学观察。眼观所见显著病变为盲肠肿胀、充血、出血 ;病理组织学变化的主要特征为盲肠卡他性或出血性、坏死性肠炎 ,并有大量不同发育阶段的球虫寄生 ;其次是十二指肠和空肠 ,表现粘膜上皮细胞肿胀、变性、坏死和血液循环障碍 ,在十二指肠也有少量不同发育阶段的球虫寄生。心、肝、脾。Chickens artificially infected with 2.4×10 5 mixed spores were examined using routine pathological methods. It was found that the obvious lesions were cecum hemorrhage and enlargement. The intestine changes were characterized by catarrhal and hemorrhagic and necrotic enteritis. A lot of parasitic coccidian of different growth phase grew in the duodenum. The epithelial cell was tumescent, denatured and macrobiotic. The blood circulation was obstructed.
