Brucella ovis as a Cause of Abortion in Ewes

American Journal of Veterinary Research, 1974
SUMMARY Brucella ovis was isolated from aborted fetuses from sheep in 3 flocks, and 1 isolate was used to reproduce the disease under experimental conditions. Abortions occurred in 3 of 9 pregnant ewes that were inoculated. Serum samples from the inoculated ewes had antibody titers with B.

Characterization of Brucella ovis surface antigens

Veterinary Microbiology, 1988
A rough antigen (SRA) extracted from Brucella ovis in hot saline by Myers procedure, showed three precipitation lines when tested in immunodiffusion against sera from experimentally infected rams. The components responsible for the lines could be isolated by ultracentrifugation or gel filtration which gave 3 fractions, named PI, PII and PIII.

Experimental infection of goats with Brucella ovis

Australian Veterinary Journal, 1985
SUMMARY: Six goats were inoculated with Brucella ovis. Two goats were inoculated with infected semen by the intratesticular route and 2 each by installation of the semen on to the nasal or preputial epithelium. All goats produced antibody responses as measured by an enzyme‐linked immunosorbent assay (ELISA) procedure and the serums of 5 goats reacted ...

Use of phage for the identification of Brucella canis and Brucella ovis cultures

Research in Veterinary Science, 1985
The brucella phage strains R, R/O and R/C standardised at routine test dilution on their propagating strains were effective in identifying cultures of Brucella ovis and B canis and in differentiating these from other non-smooth brucella isolates.

Restriction endonuclease analysis of Brucella ovis and other Brucella species

Veterinary Microbiology, 1985
Brucella ovis DNA was analysed by using 11 different restriction endonucleases. The most clearly resolved DNA fragment patterns were obtained after digestion with the enzyme Hind III. When DNA preparations from 35 strains of B. ovis were digested with this enzyme, the fragment patterns appeared to be identical.

Discrimination between sheep antibodies to Brucella melitensis and to Brucella ovis

Veterinary Microbiology, 1989
When preparations containing smooth Brucella abortus lipopolysaccharide (LPS) were used as antigen in an ELISA, strong positive reactions were obtained with sera from sheep infected with Brucella melitensis or with Brucella ovis. Oxidation of the LPS with sodium metaperiodate greatly reduced the extent of the cross-reactions with antisera to B.

Antigenic Relationship of Brucella ovis and Brucella melitensis

Journal of Bacteriology, 1967
Immune sera were prepared in rabbits by the injection of living and acetone-killed cells of Brucella ovis and smooth and rough B. melitensis . The use of whole-cell antigens in agglutination and agglutinin-absorption tests revealed little relationship between B.

Natural IS711 insertion causing omp31 gene inactivation in Brucella ovis

Journal of Veterinary Diagnostic Investigation, 2013
The present report describes an atypical Brucella ovis strain (Bo10) isolated from the epididymis and testis of an infected ram. Macroscopic and microscopic lesions characteristic for the infection, including positive Brucella immunostaining, were ...

Further Practitioner Comment on Brucella Ovis

New Zealand Veterinary Journal, 1982
Abstract Sir:- Further to the recent correspondence on Brucella ovis(18)(21) I would like to record some observations from my experiences with eradication schemes involving commercial ram flocks.
