Ja. Vanwyk et Gap. Titoy, RADIOLABELED ADULT HAEMONCHUS-CONTORTUS OBTAINED FROM EGGS VOIDED IN THE FECES OF A SHEEP INJECTED WITH FE-59, Onderstepoort journal of veterinary research, 63(3), 1996, pp. 263-264
The infective larvae of Haemonchus contortus (L3) obtained from an art
ificially infected sheep injected with 125 mu Ci of Fe-59, incorporate
d the isotope and retained ii in sufficient quantities to be detectabl
e by autoradiography in the adult worms which developed. This is appar
ently the first report of incorporation of Fe-59 into adult helminths,
of which the L3 originated from an animal that was injected with the
isotope.
