Antigenic Relationship of Brucella ovis and Brucella melitensis
Journal of Bacteriology, 1967Immune 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.

TheBrucella OvisComplement Fixation Test
New Zealand Veterinary Journal, 1983Abstract Extract Sir:- For the effective control of ovine brucellosis it is imperative that veterinarians have both a sound knowledge of all aspects of the disease and access to reliable diagnostic tests. In recent years there have been a number of submissions to this journal, concerning the accuracy and use of the Brucella ovis complement fixation ...

Brucella ovis-induced abortion in ewes
Journal of the American Veterinary Medical Association, 1983SUMMARY Aborted 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.

Experimental infection of goats with Brucella ovis
Australian Veterinary Journal, 1985SUMMARY: 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 ...

Control of Brucella ovis Infection in Sheep
Veterinary Clinics of North America: Food Animal Practice, 2011Approach to control of Brucella ovis would vary in different countries and areas depending on farm and flock characteristics and economic factors. Eradication by a test-and-slaughter approach is the most desirable option in areas where it is logistically and financially feasible.

Discrimination between sheep antibodies to Brucella melitensis and to Brucella ovis
Veterinary Microbiology, 1989When 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.

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

Brucella ovis infection in two flocks of sheep
Veterinary Record, 1994Brucella ovis infection could not be eradicated from two flocks of sheep despite serologically testing and culling the infected rams for four years. The hypothesis that the ewes played a major role in the maintenance of the infection in both flocks was investigated by using serological, bacteriological and pathological criteria.
