[Effect of gamma rays on T. ovis cysticerci]

The influence of gamma-radiation (0.2 to 2 kGy) on T. ovis cysticerci has been studied. Irradiation of flesh pieces invaded with T. ovis with doses ranging from 0.2 to 1.2 kGy does not affect the viability of cysticerci; the doses of 1.4 to 1.8 kGy have a minor effect, and the dose of 2 kGy produces a 100-per cent effect on the viability and invasive capacity of cysticerci. This effect of radiation is not influenced by the volume of the muscular flesh mass exposed, age and localization of cysticerci. With lower doses, the radiation effect is manifested 15-20 days following irradiation.
