Studies on some trematode parasites of stray dogs in Egypt with a key to the identification of intestinal trematodes of dogs

Fourteen of 30 stray dogs examined from Ismailia City, Egypt were infected with one or more species of intestinal trematodes, including Mesostephanus appendiculatus, Mesostephanus milvi, Mesostephanus fajardensis, Echinochasmus liliputanus, Heterophyes dispar, and Pygidiopsis genata. The morphology of each species was compared with earlier descriptions and a key to the identification of canine intestinal trematodes in this geographic region was developed.
