Reversible inhibition of hatching of infective eggs of Ascaris suum (Nematoda)

Hurley L. C. and Sommerville R. I. 1982. Reversible inhibition of hatching of infective eggs of Ascaris suum (Nematoda). International Journal for Parasitology12: 463–465. Dilute solutions of an oxidising agent, iodine, reversibly inhibit hatching of infective eggs of Ascaris suum. The capacity to hatch is restored by exposure to reducing agent, hydrogen sulphide. These observations add to known similarities between hatching of infective eggs and exsheathment of infective larvae. It is proposed that the regulatory mechanisms for both processes are similar.
