Collyriclum faba, tracheophilus sisowi and prosthogonimus macrorchis (Trematoda: Digenea), new records of parasitic digenea for the Philippines

Abstract

© 2019, University of the Philippines at Los Banos. All rights reserved. Native chickens (Gallus gallus domesticus L.) (N-50) were examined for digenetic trematodes at different periods whenever opportunity arose. Only organs other than the digestive tract were examined and flukes recovered following the sedimentation-decantation technique. Recovered flukes from the resulting final sediment were fixed in 80% ethyl alcohol, stained in aceto-alum carmine, dehydrated in increasing grades of ethyl alcohol, cleared in oil of cloves and mounted in Canada balsam. Three species of digenetic trematodes belonging to different families are identified namely: Collyriclum faba (Bremser in Schmalz, 1831) Kossack, 1911 (Family Collyriclidae) in the subcutaneous tissues of birds from Abra, Tracheophilus sisowi Skrjabin, 1913 (Family Typhlocoelidae) in the air sacs of birds from Ilocos Sur and Prosthogonimus macrorchis Macy, 1934 (Family Prosthogonimidae) in the oviduct and bursa of Fabricius of birds from Ilocos Sur and Laguna, Philippines. The three species are described and illustrated based on the Philippine materials. All three species are reported for the first time in the Philippines constituting new locality records for the species. Their life cycle and mode transmission are presented. The genus Prosthogonimus is discussed and the two valid species occurring in the Philippines are differentiated from each other.
