Spiculopteragia asymmetrica Infection in Cervus elaphus from Iran

Spiculopteragia asymmetrica is a gastrointestinal nematode frequently found in the abomasum of cervids. During December and February 2010, two red deer were died in Semeskandeh sanctuary in Mazandaran province. Moreover, five live deer from mentioned area were treated by Ivermectin and collected feces of these animals were used for assessment helminthes infection by parasitological methods. Several nematodes were recovered in abomasums and in fecal samples of treated animals. Number of worms recovered from abomasums of two dead animals were 275 (90 male and 185 female) from the first one and 327 (102 male and 225 female) from the second. Based on morphological characteristics nematodes were diagnosed as S. asymmetrica. This is the first report of existence of S. asymmetrica from cervids in Iran.
