广东艾美虫发育的研究

广东艾美虫寄生于乌鳢的消化道,其发育周期可分为裂体生殖、配子生殖和孢子生殖三个阶段。这三个阶段均在一个寄主体内完成。裂体生殖和配子生殖发生在幽门盲囊和前肠上皮细胞核之上方。成熟裂殖体为球形或椭圆形,含有8—14个香蕉形裂殖子。大配子的整个发育过程没有发现嗜伊红颗粒,嗜碱性颗粒在卵囊壁形成前后发生变化。成熟小配子母细胞内有许多新月形的小配子。孢子生殖在幽门盲囊和整条肠管内进行。  

A STUDY ON THE DEVELOPMENT OF EIMERIA KWANGTUNGENSIS CHEN ET HSIEH

The present paper deals with the development of Eimeria kwangtungensis Chen et Hsieh, 1960 inside its host Ophiocephalus argus. Taking place in the same host this eimerian species has three developmental stages, schizogony, viz. gametogony and sporogony. Both schizogony and gametogony occur at the place above the nucleus of the epithelia cells of pyloric caeca and anterior intestine. Mature schizonts are spheric or elliptic, with 8—14 merozoites in the shape of banana. Eosinophilic granules were not found throughout the developmental course of macrogamete. Basophilic granules vary before and after the formation of oocyst wall. Mature microgametocyte has many microgametes of crescent shape. Sporogony takes place in pyloric caeca and whole intestine.
