Abstract

An attempt was made to determine if blocking antibody is involved in protecting cysticerci of Taenia taeniaeformis against a host immune response. Immunoflourescence microscopy confirmed that host antibody is present on the parasite surface within the capsule. To test if the larvae can still survive after such a coat of blocking antibody is removed, the larvae were trypsinised and then implanted into recipients. The results indicate that blocking antibody could be involved in the survival of 1 year old established larvae. Untrypsinised larvae were normal 14 days after implantation into control or immunised rats. Trypsinised larvae implanted in control rats were alive but showed on intense cell adherence on their surface. On the other hand, trypsinised larvae implanted into immunised rats were dead and completely encapsulated. However, experiments with 1 month old larvae were inconclusive.
