摘要
作者利用致乏库蚊(Culex fatigans)作为实验媒介,把寄生在灰鼠蛇(Ptyas korros)的广东肝血簇虫(Hepatozoon guangdongensis)感染到无虫的灰鼠蛇(渔游蛇(Natrix piscator)、三索锦蛇(Elaphe radita)和中国水蛇(Enhydris chinesis);观察其生活史。首次描述了由x裂殖体产生的小裂殖子,进入红细胞,经滋养体和幼小配子母体阶段发育成配子母体的过程,以及由y裂殖体产生的大裂殖子继续在内脏进行无性生殖的细节;在对广东肝血簇虫生活史进行研究的基础上,提出一种新的肝血簇虫在脊椎动物体内发育的模式和血液时期各期虫体划分的形态学标准。
The life cycle and experimental transmission of Hepatozoon guangdongensis were described. The sporogonic cycle could be completed in two species of mosquitoes, namely Culex fatig-ans, Aedes albopitus. The parasite could be transmitted to four species of snakes: Ptays korros, Natris piscator, Elaphe radita and Enhydris chlnensis by feeding them with C. faligans carrying mature oocyst in the haemocoel.Schizogoniy is mainly in capillary endothelial cells of the lung. A micromerozoite, after liberation from X-schizont, enters a red cell and becomes a trophozoite which, when fully grown turns to be young gametocyte and eventually becomes mature gametocyte. The entire procedure of the development of a gametocyte from a micromerozoite is described here for the first time for the genus Hepatozoon. Some of macromerozoites produces by Y-schizont continue their asexual reproduction while others may turn become X-schizonts, which will complete their development in the capillary endothelial cells of the lung.The entire course of the development of the genus Hepatozoon in veterbrates may be diagrammatized as follow:
