Abstract

The literature pertaining to enhanced growth in parasitized invertebrates and vertebrates is reviewed critically. Quantitative weight and Ca++ determinations of the whole snail, shell and soft tissues of Nitocris dilatatus naturally infected with Acanthatrium anaplocami, and Physa sayii experimentally infected with Echinostoma revolutum, have shown that increased total weights of parasitized snails can be accounted for by more heavily calcified shells. Histological and histochemical studies have shown that this hypercalcification is due to an initial increase of the number and size of calcium spherites in snails under parasitic stress, followed by the release of ionic calcium into the haemolymph and tissues when spherite-containing cells are destroyed by the parasites as a normal process. The increased ionic calcium is eventually deposited in the shells.
