Il a ete constate que les larves d'Hexametra quadricornis, d'Ophidascaris sprenti et de Polydelphis quadrangularis (parasites de serpents) subissent la premiere et la seconde mues lorsqu’elles sont encore localisees a l’interieur de la coque des œufs, et non seulement la premiere mue, comme il etait admis jusqu’a present. Ainsi, elles sont deja au troisieme stade du developpement et non au second quand elles atteignent l’hote intermediaire.Ces observations permettent d’expliquer pourquoi la seconde mue etait caracterisee principalement par des modifications morphologiques au niveau de la queue des larves localisees dans l’hote intermediaire, sans que le decollement de la cuticule ait ete constate de facon precise.read more

TL;DR: St studies on 300 worm-free chickens infected with Ascaridia galli indicated that the histotropic phase is a normal part of the life cycle and that it involves both second- and third-stage larvae, and the involvement of host antibodies in the induction of the arrested state is suggested.
