The Fate of Eggs and Larvae of Ascaridia galli in Earthworms

Abstract

Earthworms were found to retain eggs and larvae of Ascaridia galli very briefly, and transmission can be attributed only to such eggs or larvae in transit in the digestive tract. Larvae of A. galli do not accumulate as do the larvae of Heterakis gallinarum, for the larvae of A. galli are voided within 48 hr of ingestion of the eggs. Since these larvae are unprotected, they must usually die, having little opportunity to gain access to a definitive host.
