title: Concurrent infections of cecal trematodes, Zygocotyle lunata, and Notocotylus sp., in the domestic chick and observations on host-parasite relationships of Notocotylus sp.
abstract: Single and concurrent infections of cecal trematodes, Zygocotyle lunata and Notocotylus sp., were studied in controlled, laboratory infections in the domestic chick. The recovery of Notocotylus sp. from the chick cecum was reduced significantly in the presence of Zygocotyle lunata. Neither the size nor the distribution of either helminth was affected by the presence of the other. The ventral surface of Notocotylus sp. was associated intimately with the cecal villus, and this fluke fed on host blood.
