摘要:

【提要】  用华支睾吸虫囊蚴灌胃感染昆明小鼠(20个/鼠)。于感染后0.5、1、2、4、8、16、32和64 h处死小鼠。发现小鼠的胃和小肠均有囊蚴脱囊,主要见于十二指肠。脱囊时间集中在感染后2、4、8和16 h。感染后0.5 h即在肝胆管发现童虫,随着感染时间的延长,虫体数量也随之增多,但至32 h后肝胆管内虫数不再增多。

Abstract:

【Abstract】 Metacercariae of Clonorchis sinensis (20 per mouse) were given orally to Kunming mice. The mice were sacrificed at 0.5, 1, 2, 4, 8, 16, 32, and 64 h after infection. The results showed that the excystation of the metacercariae occurred in the stomach and small intestine, mainly in the duodenum. Excystation occurred mainly at 2, 4, 8, and 16 h post-infection. Juveniles were found in hepatic duct on 0.5 h post-infection. The number of juveniles increased with the extension of infection time, which kept unchanged in hepatic duct from 32 h after infection.

Key words: Clonorchis sinensis, Metacercaria, Excystation
