Original Article


A 9 years old bull was presented to the hospital with a history of scrotal swelling for a period of 12 days and progressive emaciation with intermittent fever. Clinical examination revealed the swollen and painful scrotum with fluid thrill, mild abduction and disorientation of hindlimbs were noticed. Ultrasonography of the testes revealed the anechoic fluid in between the visceral and parietal layers of tunica vaginalis of testis with variation in the echogenicity of the testes. Stained peripheral blood smear examination revealed the presence of Trypanosoma evansi organisms. The bull was administered with diminazene aceturate, enrofloxacin, flunixin meglumine, multivitamin injections and dextrose normal saline. Uneventful recovery was noticed following the therapy.
