''Setaria cervi'' is a species of parasitic roundworm belonging to the genus ''Setaria''. It infects cattle, bison, yak, reindeer, buffalo, moose, and sheep all over the world. It is most prevalent in Europe and Asia. Different species of ''Aedes'' mosquito can transmit the filarial worm. Stable fly ''Haematobia stimulans'' is the major vector. The mature roundworms are primarily present in the abdominal (peritoneal) cavity, but are capable of migrating to central nervous system causing serious neurological disease. ==Description==
''Setaria cervi'' shows sexual dimorphism as a typical roundworm. Males are relatively smaller measuring 50 mm long and 40 μm wide, while females are much larger measuring 100 mm long and 750 μm wide. Males can be distinguished from those of other species from showing horn-like lateral appendages and characteristic striated bands on the ventral side of the tail. The larvae (microfilariae) are very small and only about 200 μm long. The infective larvae are about 2 mm.
