Actinobacillus seminis infection in rams
Diagnosis
History, clinical examination (particularly for orchitis in young rams). Demonstration of A seminis on culture of semen.
Specimens required
1. Semen sample collected aseptically, submitted chilled.
2. Serum sample, submitted chilled (to eliminate Brucella ovis as a cause).
3. Testes, epididymes and accessory sex glands including ampullae and seminal vesicles submitted chilled.
NB.
The CF test on serum is not a reliable test for A seminis.
