| 摘要: |
| 本文描述了寄生于北京鸭小肠上皮杯状细胞中的菲莱氏温扬球虫滋养体、裂殖体、裂殖子、大配子体的超微结构,并与寄生干吸收上皮细胞的同种虫体以及鸡十二指肠杯状细胞中的Eimeria acervulina 作了比较。整个裂殖生殖(包括成熟裂殖子的形成)可在杯状细胞中进行。发育中的大配子体(早、中期大配子体),可在杯状细胞内生长,但未见小配子体在其中发育。裂殖生殖时期虫体常寄生于杯状细胞的胞质内,而大配子体多见于杯状细胞的粘液颗粒之中,此与 E.acervulina 不同。所见各期虫体在杯状细胞内发育正常,其结构与在吸收上皮寄生者相同。 |

| Abstract: |
| The fine structure of trophozoites,schizonts,merozoites and macrogamonts of Wenyonella philiplevinei found in goblet cells of the intestinal epithelium of Pekin duck is described.Observations revealed that the whole cycle of schizogony could be completed in globet cells.Developing macroga- monts,including young and intermediate stages also be found in goblet cells, but the authors failed to find microgamonts in these. |
