Epidemiological Observations in a Corriedale Flock affected by Brucella ovis
Veterinary Research Communications, 1998Brucellosis in sheep, caused by Brucella ovis, is primarily a chronic infectious disease of rams with epididymitis as its most characteristic lesion. Six hundred rams from an infected farm were clinically and serologically examined once a year, over a 3-year period. An increase from 2.1% to 6.3% in the prevalence of animals serologically positive to B.

Brucella ovis-induced abortion in ewes.
Journal of the American Veterinary Medical Association, 1983Aborted fetuses and placental tissue from ewes in 2 flocks were submitted for diagnostic examinations. Brucella ovis was isolated from fetal lung or abomasal contents, or both. Placentitis was a consistent gross lesion. Microscopic lesions included suppurative pneumonia and placentitis.

Observations onBrucella ovisCFT results
New Zealand Veterinary Journal, 1978Abstract Three commercial flocks, deriving replacement rams from 15 parent studs, had respectively 33 of 71,13 of 31 and 8 of 82 rams positive to the Br. ovis CF test. In the first flock, clinical findings supported a diagnosis of active Brucella infection. In the other two flocks, positive results were attributed to vaccinational titres persisting for

An improved immunoblotting technique for the serodiagnosis of Brucella ovis infections
New Zealand Veterinary Journal, 1997Two antigen preparations, the routinely used Brucella ovis sodium dodecylsulfate-mercapto ethanol extract and a B. ovis Triton X-114-derived detergent-rich phase, were compared under standard conditions for their use in electrophoretic immunoblotting for confirmafory, serological testing for B.

Immunization with Brucella melitensis Rev 1 against Brucella ovis infection of rams
Veterinary Microbiology, 1987The efficacy of Brucella Melitensis Rev 1 vaccine (Rev 1) for the prophylaxis of Brucella ovis ram epididymitis was evaluated. Twenty-nine 3-month-old rams were vaccinated with 2 X 10(9) Rev 1 and 14 were revaccinated with 5 X 10(8) at 14 months of age. Six rams remained unvaccinated as a control group. All rams were challenged with 5 X 10(8) B.

Efficacy of Brucella suis strain 2 vaccine against Brucella ovis in rams
Vaccine, 1993The protective efficacy against Brucella ovis of live vaccine Brucella suis strain 2 (S2) and Brucella melitensis strain Rev 1 has been evaluated in rams. Fourteen 4-month-old Brucella-free Aragonesa rams were vaccinated conjunctivally with 2 x 10(9) c.f.u. S2.

Pathogenesis of Epididymitis Caused by Brucella ovis in Laboratory Animals
American Journal of Veterinary Research, 1973SUMMARY With the purpose of selecting an animal model for the study of infection caused by Brucella ovis, various laboratory animals such as mouse, Lewis rat, Wistar rat, gerbil, hamster, guinea pig, and rabbit were inoculated with B. ovis. The strain of B. ovis used is one recently isolated from a naturally infected ram.

An immunoblotting technique for the serodiagnosis of brucellosis by Brucella ovis.
The new microbiologica, 2000An immunoblotting (IB) technique was developed for the serodiagnosis of brucellosis caused by Brucella ovis. Immunoblotting was performed, using a B. ovis HS (hot saline extract) antigen, on 44 blood serum samples which came from rams belonging to known brucella-free flocks, 114 samples originating from ten experimentally B.

Duration of Brucella ovis infection in ewes.
The Cornell veterinarian, 1975Twenty Romney Marsh ewes, some 5 to 40 days pregnant, were inoculated with a strain of Brucella ovis onto the scarified mucous membrane of the vagina. Establish of infection was ascertained by recovery of the organisms from blood; supramammary and inguinal lymph nodes; the vagina, after initial disappearance of the organism from this organ; and the ...

An overview of Brucella ovis infection in New Zealand
New Zealand Veterinary Journal, 2002Abstract Extract Brucella ovis is a bacterial disease that causes epididymitis and reduced fertility of rams. It is an important cause of ram wastage in sheep flocks in most parts of the world with the exception of Great Britain (Lawrence 1961). The earliest report of disease caused by the organism now known as B.
