How do rams get brucellosis?
Ovine brucellosis is caused by infection of the sheep with Brucella ovis bacteria, found in the semen of infected rams, in foetal fluids and in the mammary glands of infected ewes. This Primefact contains information on the following: Differences between normal and affected reproductive organs in the ram.
What is the sheep disease in rams?
Ovine brucellosis occurs naturally only in sheep. It is a disease primarily of rams. Ewes usually only carry the infection for one or two oestrus cycles. In rams the disease causes inflammation of the epididymis (the vessel which transports semen from the testes).
What is the most common lesions problems associated by Brucella ovis in rams?
Infectious epididymitis is most common and important in rams. It occurs in two main ways in rams: hematogenously by Brucella ovis and by ascending infection with bacteria such as Actinobacillus seminis, Histophilus somni, and Escherichia coli.
Is Brucella ovis zoonotic?
B. ovis is stably rough, and it is one of the two classical Brucella species that do not have zoonotic potential. In sheep, the organism causes either clinical or sub-clinical chronic infections characterized by epididymitis, orchitis, male infertility, and occasionally abortion in pregnant ewes [15].
What is ovine Johne’s disease?
Ovine Johnes disease (OJD) is caused by infection with the bacteria, Mycobacterium paratuberculosis. OJD is a chronic infection of the bowel. This causes the lining of the bowel to thicken and reduces the absorption of food. Affected sheep show severe wasting. Chronic scouring may occur.
