Summary

Daughter cysts 0.2–3.0 mm in diameter from secondaryEchinococcus granulosus cysts, collected from mice one year after experimental infection, were transferred to fresh mice.

The metacestodes developed into larger cysts showing fertility and daughter cyst formation at autopsy 9–14 months post infection. The average total growth of all cysts per mouse expressed in log weight (mg) amounted to 0.25±0.03 per month. Thus, for the maintenance of the parasite in mice, daughter cysts can be used as successfully as protoscolices and small ‘latent’ cysts.
