用扫描电镜观察表明,经长或短潜伏期后发病患者的间日疟原虫,在中华按蚊体内卵囊和子孢子发育过程及各期形态基本相同。早期卵囊表面光滑,随着卵囊继继发育增大,其表面出现皱褶。囊壁内侧面比较粗糙。囊内发育以细胞质伸出小突起(子孢子芽),出现裂隙开始,成孢子细胞形状不一,子孢子芽或成排从成孢子细胞伸出,或呈放射状排列。成孢子细胞残余体呈圆形或椭圆形,表面光滑,或有小突起及浅表皱褶。游离子孢子开始聚集成团,并在囊内活动,最后,从囊壁小孔逸出,或从囊壁上的裂口大量涌出。子孢子逸出后在蚊胃上只留一个空囊。子孢子细长,多数呈 C 字形,表面光滑,前端稍平,在虫体部前约1/3处可见微孔。
Scanning electron microscopy showed that the development of oocysts and sporozoites in Anopheles sinensis were similar during the long or short latency incubation period. Early oocysts smooth surface, with the subsequent development of oocysts increased, the surface folds. Wall inside the relatively rough surface. The cytoplasm develops cytoplasm protruding small protuberances (sporozoite buds), where fissures begin, sporozoite cells vary in shape, sporozoite buds or rows protrude from the sporozoite cells, or are radially arranged. Spore cell residual body was round or oval, smooth surface, or small protrusions and superficial folds. Sporozoites began to aggregate into clusters, and in the activity of the capsule, and finally, escape from the small holes in the wall, or from the wall of the large number of wells gushing. After the sporozoites escaped, only one empty capsule was left on the mosquito’s stomach. Sporozoites slender, most were C-shaped, smooth surface, the front slightly flat, about 1/3 in front of the worm body can be seen microporous.
