Oesophagus has strong posterior bulb having valvular apparatus. Heterakis gallinarum is not directly preyed upon, but eggs which have been released into the soil can be eaten by other bird species, earthworms, and insects such as flies and grasshoppers. Heterakis isolonche, highly pathogenic in pheasants, may cause 50% mortality. Death of ova due to irregular cleavage, caused by damage to the nucleus was more frequent in A. galli, while death due to damage to the protoplasm occurred more often in H. gallinae ova.
