| ''Brucella abortus'' is a species of the ''[[Brucella species - Overview|Brucella]]'' bacteria genus and causes [[Brucellosis - Cattle|bovine brucellosis]]. It mainly affects cattle, where transmission is by ingestion and abortion occurs in the last half of pregnancy. The placenta is covered by fibrinonecrotic tissue and the foetus often shows bronchopneumonia. | | ''Brucella abortus'' is a species of the ''[[Brucella species - Overview|Brucella]]'' bacteria genus and causes [[Brucellosis - Cattle|bovine brucellosis]].

− | ''B.abortus'' uncommonly localises in joints, usually in '''carpal bursitis (hygroma)''' in cattle and '''bursitis''' in horses. Also in spleen and lymphatic tissue of non-pregnant animals. It has been isolated from closed cases of [[Bursae and Tendons Inflammatory - Pathology#Poll Evil and Fistulous Withers|poll evil and fistulous withers]] in horses. | + | ''B.abortus'' uncommonly localises in joints, usually in [[Capped Joints|'''carpal bursitis (hygroma)]]''' in cattle and '''bursitis''' in horses.

| Vaccination of heifers against ''B. abortus'' in endemic regions by Strain S19, a live attenuated vaccine, stimulating a cell-mediated immune response. The vaccination of young animals interferes with serological testing. The 45/20 bacterin vaccine is less effective and the newer RB51 vaccine has no LPS O-antigen therefore not detected by serological tests and gives good protection. | | Vaccination of heifers against ''B. abortus'' in endemic regions by Strain S19, a live attenuated vaccine, stimulating a cell-mediated immune response.
