Abstract

The infective larvae of Haemonchus contortus (L3) obtained from an artificially infected sheep injected with 125 µCi of ⁵⁹Fe, incorporated the isotope and retained it in sufficient quantities to be detectable by autoradiography in the adult worms which developed. This is apparently the first report of incorporation of ⁵⁹Fe into adult helminths, of which the L3 originated from an animal that was injected with the isotope.
