Abstract:Pleroceroids Spirometra mansoni were obtained from the wild snakes Elaphe carinate. A total of 30 Kunming mice (20~25 g) equally divided into 10 groups, and fed each with 5 pleroceroids (3 mice/each group) and killed at designed time points from 10 minutes to 14 days. Autopsy was performed on each mouse to recover the pleroceroids. The results indicated that the pleroceroids penetrated into the stomach or small intestine wall as early as 10 minutes after infection, and the process could be finished within 20 minutes and subsequently appeared in abdominal cavity. After 10 minutes to 6 hours, most pleroceroids appeared in gastrointestinal lumina, gastrointestinal walls and abdominal cavities of mice. After 1 day post infection, a few pleroceroids migrated to subcutaneous tissue and most pleroceroids appeared in subcutaneous tissues within a week. A total of 14 pleroceroids were found in subcutaneous tissues, and among of which, 7 were observed around neck region, 6 around trunk and 1 in the head of mice. No pleroceroid was found in the brain, heart, liver, kidney and lung tissues of infected mice.
