Extract

Experimentally we have demonstrated what Lee (1969, 1971 a, b) postulated on the basis of morphological considerations. The female heterakid is capable of transmitting H. meleagridis from the bird to the caecal worm egg without the intervention of the male except for fertilization. If the male is otherwise involved in the transmission of H. meleagridis, it seems unlikely that its role is of appreciable significance in the life-cycle of the histomonad as we know it now. However, if as believed by many, the histomonad was originally a parasite of a nematode that may not have been an obligatory parasite, the role of the male worm may have been considerably more important to the survival of the histomonad.
