摘要
9头犊牛皮下接种弓形体滋养体,分期扑杀,2头犊牛作为对照。其主要脏器病理形态学观察结果表明:显著的炎性细胞浸润、血管损伤及其相关变化构成了其病变的特征;肝细胞线粒体钙化;肾小管上皮细胞内出现环状巨型线粒体;肾小管上皮形成环状裂隙,上皮下基膜物质沉积;脏器病变多见于急性感染期。本文讨论了显著的炎性细胞浸润与牛抗弓形体感染能力的关系。
Each of nine calves was inoculated subcultane ously with tachyzoites of Toxoplasma. Two calves were kept uninoculated as controls. The calves were killed at intervals. The pathomorphological studies of the major organs of the infected calves showed that main characteristic changes were significant infiltration of inflamatory cells and destruction of blood vessel walls and a series of lesions relative to the latter in the organs; There were cacific mitochondrias in the liver cells and ring-shaped megamitochondrias in the convoluted renal cells; The kidney had ring-shaped rifts between the convoluted cells and their basement membranes, on which deposits were seen; The lesions of the organs were mainly seen at acute period. This paper discusses the relationship between marked infiltration of inflamatory cells in the organs and the calves'resistance to Toxoplasma
