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.

Brucella ovis infection in two flocks of sheep

Veterinary Record, 1994
Brucella 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.

TheBrucella OvisComplement Fixation Test

New Zealand Veterinary Journal, 1983
Abstract 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 ...

Cholinesterase's activities of infected mice by Brucella ovis

Microbial Pathogenesis, 2019
The role of cholinesterase in inflammatory reactions has been described in several infectious diseases. However, in Brucella spp. this has not yet been studied. Therefore, the objective of this study was to evaluate whether experimental infection by Brucella ovis alters the cholinergic activity in pro- or anti-inflammatory responses to the disease. For

The Complement Fixation Test Forbrucella Ovis

New Zealand Veterinary Journal, 1981
Abstract Sir:- A project to investigate the efficacy of the complement fixation test (CFT) for the diagnosis of Brucella ovis infection in rams has recently been completed. The investigation was undertaken by field and laboratory staff of the Division of Animal Health and several practitioners. The results of CFT's done with 3 antigens by waim and cold

Epidemiological Observations in a Corriedale Flock affected by Brucella ovis

Veterinary Research Communications, 1998
Brucellosis 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, 1983
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.

Observations onBrucella ovisCFT results

New Zealand Veterinary Journal, 1978
Abstract 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
