*Bovine brucellosis:
**Caused by ''Brucella abortus''
**Eradicated in many countries including UK
**Infection usually by ingestions but also venereal, skin abrasions, inhalation, transplacental
**Abortion storms in susceptible herds
**Abortion after fifth month of gestation due to placentitis
**Brucellae excreted in foetal fluids for 2-4 weeks following abortion and at subsequent parturitions without abortion
**Infection of mammary glands and lymph nodes persists for years
**Excreted intermittently in milk for years
**Seminal vesicles, ampullae, testicles and epididymus infected in bulls; necrotising orchitis
**Decreased fertility in cows and bulls; decreased milk production
**Localisation in [[Spleen - Anatomy & Physiology|spleen]] and lymphatic tissue of non-pregnant animals
**Occasionally causes [[Joints Inflammatory - Pathology#In Cattle|arthritis]]
*Isolated from closed cases of [[Bursae and Tendons Inflammatory - Pathology#Poll Evil and Fistulous Withers|poll evil and fistulous withers]] in horses
