摘要
观察山羊球虫病的临床症状、病理变化和球虫的内生殖阶段。利用光镜或扫描电镜检查小肠壁上的4种肉服病变:白色小点、平斑、突起斑和息肉。它们中都有大量的虫体寄生。息肉基部有一层厚厚的腺样上皮形成的腺。肠系膜淋巴结水肿,被膜下、小梁周围的淋巴窦和淋巴管中有大裂殖体和卵囊存在。发现两种类型的裂殖体:大裂殖体和小裂殖体,前者寄生于小肠绒毛的中央乳糜管和肠系膜淋巴结中,后者大多寄生于肠腺上皮细胞中,少数在绒毛上皮细胞中。裂殖子、配子体和卵囊寄生于肠腺及绒毛上皮细胞中。
The histopathological changes of coccidiosis of goats and endogenous stages of coccidia were studied with light microscope and / or scanning electron microscope. There were four types of gross lesion in the small intestinal wails:white spots, flat patches, raised patches and polyps. The basees of polyps, formed by crypt-like epithelium, were occupied by a number of crypts. Atrophy of villi, necrosis of the epithlia of intestine and crypts of lieberkuhm, infiltration of inflammatory cells and congestion and hemorrhage of capillaries in lamina propria and submucosa were shown in some areas of intestine. Mesenteric lymph nodes were edematous and some giant meronts and oocysts were found in their cortical sinuses and lymphatic vessels. Two types of meronts were found. The giant meronts were in central lacteals of the villi of small intestines and mesenterie lymph nodes, and small meronts mostly in epithelial cells of the crypts and less often in those of the villi of small intestines. The mcrozoites, gamonts and oocysts were in the epithetial ceils of villi and those of crypts.
