Brucellosis (sheep)

Also known as ovine brucellosis


Description

Ovine brucellosis is caused by Brucella ovis which is carried by sexually mature rams and spread by direct contact or passive venereal infection. Clinically affected rams have a history of infertility and present with palpable lesions of the epididymis. Although not common, ewes infected with Brucella ovis can occasionally abort. Actinobacillus seminis is another potentially infectious organism which can cause epididymitis and can be tested as a differential diagnosis.

Diagnosis and tests available

Diagnosis

Diagnosis is based on the result of a clinical examination and serology, supported in some cases by bacteriological culture or PCR of semen. Ram semen culture package includes testing for B. ovis. A. seminis and H. somni.
