Summary

Domestic chicks were fed either a single cyst or ten cysts ofZygocotyle lunata. There was no significant difference in the length ofZ. lunata adults from single- or ten-cyst infections in the cecum of chicks after 7, 14, 21, and 28 days. Single worms produced eggs which contained fully developed miracidia. Histologic observations showed that single worms were capable of self-fertilization. Although no evidence was found that worms from ten-cyst infections were capable of cross-fertilization, eggs from these worms contained significantly more fully developed miracidia than those from single worms.
