Abstract

The life cycle of Physocephalus dromedarii was studied under experimental conditions. Larvae obtained from naturally infected Scarabaeus cristatus and Aphodius sp. (Coleoptera: Scarabaeidae) were measured and examined in light and scanning electron microscopy and used to infect a dromedary as final host as well as chicken, mice and a toad as possible paratenic hosts. Larvae with the same morphology and similar measurements were found in naturally infected reptiles (Trapelus flavimaculatus, Eryx jayakari, Cerastes gasperettii). Body length of examined larvae varied between 1450 and 1700 μm. Dorsal, ventral and lateral lips, peg-like papillae and amphideal pits are located on the cephalic cone. There are two asymmetrical cervical deirids, long simple lateral wings and a knob-like posterior end covered with minute spines. In the camel, patency is reached within 12 weeks after infection while larvae in paratenic hosts migrate into the wall of the alimentary tract and become dormant.
