Abstract:
Two male Japanese Black calves developed an enlarged scrotum and testis. Orchiectomy was performed and pus was collected during surgery. After removal of the testis, bacteriological and histopathological examinations were conducted to investigate the cause and confirm the diagnosis. Based on the results obtained, both cases were diagnosed with epididymitis caused by an infection with Pasteurella multocida. This is the first study to show that P. multocida causes epididymitis in male calves. Further studies are required to clarify the details underlying the infection of calves with P. multocida.
