Physiology of the Hatching of Eggs of Ascaris lumbricoides

Abstract

SEVERAL methods have been described for hatching eggs of A. lumbricoides in vitro 1,2. These methods, however, give little indication of the processes which may occur in vivo. An understanding of physiological processes of hatching of the eggs has been sought by applying a form of the hypothesis of Rogers and Sommerville3 which has been useful in examining the exsheathment of third-stage ‘larvæ’ of trichostrongyles. The modified hypothesis postulated that hatching of eggs would involve two processes: (a) stimulation by the host causing the egg contents to produce a hatching fluid and (b), the action of the hatching fluid on the egg shell.
