Abstract:
Trichostrongylus colubriformis infective larvae were subjected to various levels of γ-irradiation and administered to guinea pigs. The worms surviving were subsequently counted. Irradiation with 12.9 C kg− inhibited worm establishment but lower doses neither influenced worm establishment nor survival.
