Abstract
Hymenolepis nana eggs received gamma irradiation at levels from 10000 r to 200000 r before administration to mice orally or by subcutaneous inoculation. Little growth beyond the oncosphere occurred after 50000 r or over, but invasiveness was not abolished even after treatment at 200000 r. A full range of developmental stages occurred after 10000-20000 r but relatively few worms became gravid in the intestine. Growth occurred after treatment at 30000-40000 r, but very few reached the fully developed cysticercoid stage.
