LESIONS CAUSED BY CORYNEBACTERIUM PSEUDOTUBERCULOSIS IN THE SCROTUM OF RAMS

SUMMARY Palpable lesions within the scrotum but not associated with the testis or epididymis were detected in 20 of 200 merino rams in 3 flocks during routine veterinary examination. In 13 of 15 rams further examined Corynebacterium pseudotuberculosis was isolated from the lesions, which were typical CLA type abscesses. C. pseudotuberculosis was not shed in semen, and semen quality was normal in all affected rams.
