| Abstract | ||||
| Three Crocodilus niloticus were collected from Lake Naser and examined for the presence of nematode parasites that were transmitted via fish intermediate host. The examination revealed the detection of adult males and females Dujardinia dujardini (Travassos, 1920) in one of them as a first report in Egypt. The second crocodile was infested with Amplicaecum species larvae, while the third one was found free. Experimentally, the patterns of transmission of Dujardinia dujardini to fish as intermediate host with and without using invertebrate host (Cyclops) was done revealing the role of such crustacean as paratenic host. Morphological description of the adult Dujardinia species, Amplicaecum species larvae as well as the obtained stages during the experimental transmission was described and microphotographed. | ||||
