中华巨囊吸虫(Megacystium sinensis)是从广西猕猴(Macaca mulatta)体内检获的一种小型枝腺科吸虫。本文运用组织形态学方法对该虫形态特征作进一步观察。虫体的排泄囊很大,顶部有两个长35～37μm呈V形管状排泄管,排泄囊壁黏膜单层柱状上皮。卵巢、卵黄腺、梅氏腺与输卵管连接,输卵管连接子宫。阴道开口生殖孔与子宫末端连接,阴道壁具有厚的肌肉质,阴道内有虫卵。雄茎囊很大,椭圆形,雄茎囊开口生殖孔,末端位于腹吸盘背后。雄茎囊内有S弯曲射精管、U形贮精囊和输精管。射精管中段黏膜表面有条束状肌肉组织。输精管位于雄茎囊末端,在腹吸盘背面分成2支与2睾丸内侧连接。本文补充了该虫排泄囊、雄茎囊和雌性生殖器官的形态特征。
Megacystium sinensis is a small, gonadal, juvenile gnat that has been seized in Macaca mulatta. In this paper, morphological characteristics of the morphological characteristics of the worm for further observation. Parasites excretion large body, the top of two long 35 ~ 37μm was V-shaped tubular drainage tube, excretory gastric mucosa monolayer columnar epithelium. Ovary, yolk gland, plum gland and fallopian tube connection, fallopian tube connection uterus. Vaginal opening reproductive hole and the end of the uterus is connected, the vaginal wall has a thick muscle, vaginal eggs. Male stem capsule large, oval, male stem cysts open reproductive pore, the terminal is located behind the abdominal suction cup. Stem stem capsule S curved ejaculatory duct, U-shaped seminal vesicle and vas deferens. The middle ejaculatory mucosal surface of a bundle-like muscle tissue. The vas deferens are located at the ends of the male stem sac and are divided into two on the back of the abdominal suction cup and connected to the inside of the 2 testicles. This article complements the morphological features of the pest excretion sac, the male stem sac and the female reproductive organ.
