Abstract
Rabbits vaccinated by intramuscular injection with the viable eggs or the activated embryos of Taenia pisiformis, T. ovis or T. hydatigena, were subsequently challenged per os with eggs of T. pisiformis A single intramuscular injection of viable eggs or activated embryos of T. pisiformis induced a relatively solid immune response to the establishment and also to the long-term survival of the challenge infection of T. pisiformis. A single intramuscular injection of the activated embryos of both T. ovis and T. hydatigena also induced some resistance to the establishment and long-term survival of a challenge infection with T. pisiformis but no significant immune response to a similar challenge infection was detected in those rabbits vaccinated with the viable eggs of these two sheep metacestodes.
