title: Septic orchitis in an alpaca.
abstract: An adult, intact male alpaca was presented with an acute onset of unilateral scrotal swelling. Following complete physical and ultrasonographic examination, the most likely differential diagnoses were orchitis, hematoma, and testicular torsion. The animal was castrated and histopathologic evaluation revealed unilateral orchitis. Streptococcus equi subsp. zooepidemicus was cultured.
