Studies on Egyptian Trematodes with Special Reference to the Heterophyids of Mammals. I. Adult Flukes, with Descriptions of Phagicola longicollis n. sp., Cynodiplostomum namrui n. sp., and a Stephanoprora from Cats

Abstract

This report is based on a study of part of an extensive collection of helminths from vertebrates examined in Egypt and the Middle East. Ten species of heterophyid trematodes were identified in a collection of flukes obtained from 48 cats, 3 dogs, a fox (Vulpes vulpes), 2 shrews (Crocidura olivieri), a rat (Rattus rattus) and several birds (5 kites, Milvus migrans; an osprey, Pandion; and a domestic duck) in Lower Egypt. Heterophyes heterophyes occurred in the majority of cats and dogs, in the fox and in man. On the basis of a study of specimens from Egypt and the Yemen (Arabia) it is believed that there are only 2 species (H. heterophyes and H. aequalis) of this genus in the Middle East. H. aequalis is believed to be synonymous with H. dispar. Three species of Haplorchis, H. pumilio, H. yokogawai and H. taichui were encountered as well as Stellantchasmus falcatus, 2 species of Phagicola, P. ascolonga and P. longicollis, n. sp., Pygidiopsis genata and Stictodora sawakinensis. In addition to heterophyids, Echinochasmus liliputanus, Stephanoprora denticulatoides, Mesostephanus appendiculatus and Cynodiplostomum namrui n. sp. were also taken. Two new species are described Phagicola longicollis from the intestine of a domestic cat; and Cynodiplostomum namrui from intestine of both cats and dogs.
