title: Brucellosis induced by RB51 vaccine in a pregnant heifer.
abstract: Brucellosis developed in a 14.5-month-old Gelbvieh heifer after the animal was vaccinated with the calfhood dose of strain RB51 Brucella abortus vaccine s.c. during the fourth month of its first pregnancy. The heifer experienced dystocia and was euthanatized during cesarean section because of a large uterine tear. The fetus was dead at delivery. Suppurative placentitis and fetal pneumonia were evident at necropsy. Brucella abortus strain RB51 was isolated from the placenta and the fetus' lung.
