Abstract :

     A four year old mixed breed native stallion was referred to the large animal clinic of the Islamic Azad University of Tabriz in spring of 1386. Tachycardia, Tachypnea and severe colic pains were observed in preliminary physical examination. Eosinophilia and lymphocytopenia was observed following total red and white blood cell counts and differentiated white blood cell counts. Ultimately, orchitis and hydrocel was diagnosed and following castration and dissection of scrotum and testes, 10 adult nematodes were removed from the testicles. The adult worms diagnosed under stereomicroscope following translucidation by lactophenol in the parasitology laboratory and setaria equine infestation was confirmed.
