Abstract: Objective To explore the developmental maturity of Clonorchis sinensis in experimental mice, and to understand whether it is different from the naturally infected C. sinensis in humans. Method Eight experimental mice were intragastrically infected with C. sinensis cysticercosis. After 3 weeks of infection, the mouse feces were examined by washing and sedimentation method every other day. After the eggs were detected in the feces, the mice could be killed to obtain the worms. The parasites obtained from mice were stained with acetic magenta, and the specimens were compared with the specimens of C. sinensis obtained from human natural infection to measure the overall and internal structure. Result C. sinensis matured in 23 days in experimental mice. The whole size, oral sucker, abdominal sucker, pharynx, uterus, ovary, seminal vesicle, testis and eggs of C. sinensis adults obtained from mice were smaller than those obtained from humans. Conclusion C. sinensis can mature in mice, but it is smaller than the adult worms obtained in humans.
