【摘要】 作者观察了毁灭泰泽球虫和菲莱温扬球虫人工感染病例的不同肠段切片,认为: 一、泰泽球虫 病变的显现时间主要集中在96～120小时之间。病变部位限于十二指肠至空肠中段(特别是空肠前环至卵黄蒂前后)。病变性质为出血性脱屑性卡他性肠炎。感染后36～84小时在绒毛顶端上皮中发育第一代裂殖体,96小时在固有层发育第二代裂殖体。其发育形式很象E.tenella。有趣的是,96～107小时间,有性繁殖与无性繁殖同现,不同时期和不同大小的裂殖体共存于绒毛上皮和固有层的不同部位。这种世代混杂的现象,文献中无记载。究竟是1～2个世代的延续,还是更多世代的表现,值得进一步研究。104～107小时,在肠壁的血管中见吞噬细胞中含有裂殖体。它可通过门脉系统转移到肝。这是机体的防御表现。 二、温扬球虫: 病变的出现时间为36～98小时;病变部位是从卵黄蒂段至回肠,且限于绒毛顶端;病变性质为卡他性肠炎。无性繁殖有三代,1、2代在绒毛顶端的上皮中发育,第3代和配子生殖是在上皮的基膜下发育、成熟。更多还原

【Abstract】 Various segments of the intestine of experimentally infected ducklings with Tyzzeria perniciosa or Wenyonella philiplevinei were studied.The authors found:1. In the experiment with Tyzzeria perniciosalesions could be clearly seen mainly at 96-120 hours after infection. They were ohly seen in the duodenum and the middle part of the jejunum ( especially from the anterior annulus of the jejunum to the area above and below the yolksac diverticulum ) and characterized by hemo-rrhagic and desquamative catarrhal enteritis.At 36-84 hours schizonts of the first generation appeared in the epithelial cells of the distal part of the intestinal villi.At 96 hours schizonts of the second generation were seen. The endogenous cycle of this i species is comparable to that of E. tenella in the chicken.It is very interesting that at 96-107 hours both schizogony and ga-metogony were seen simultaneously. There were schizonts of various stage and size in the epithelial cells and lamina propia of the intestinal villi. So far this phenomenon has not been recorded in the literature. It is worth further studying whether it is the extention of the first and second generations or the expression of more than two generations.At 104-107 hours the macrophages, phagocytized the schizonts,wereseen in the blood vessels of the intestinal wall.They were transported to the liver via portal system and this is the phenomenon of the protective activity of the organism.2. In the experiment with Wenyonella philiplevineiLesions appeared at 36-98 hours, the locations of them were from the segment of the yolksac diverticulum to the ileum, only in the distal part of the intestinal villi. The lesions observed were catarrhal enteritis.Three generations of the schizogony were seen.Schizonts of the first and second generations developed in the epithelial cells of the distal part of the intestinal villi. Schizonts of the third generation and their ga-metogony developed and matured beneath the basal membrane of the intestinal mucosa.更多还原
