对受感染的母牛及其小牛进行的一项为期 2 1/2 年的研究证明，在自然条件下，牛布鲁氏菌病可以从母牛传播给后代。这头母牛在第一次妊娠后产下一头足月小母牛。小牛一直和它的母亲在一起直到7个月大，然后被隔离直到繁殖。在第一次妊娠期间，第二代小母牛的流产布鲁氏菌血清呈阳性。后来，她产下一头患有流产 B 型杆菌感染的小牛，通过从小牛的胃内容物、心脏血液、肺和脾脏中分离出 1 型流产 B 型杆菌来确定。从母鼠的胎盘和乳汁中也分离出了相同的微生物。
Transmission of bovine brucellosis from dam to offspring under natural circumstances was demonstrated in a 2 1/2-year study of an infected cow and her calf. The cow delivered a full-term heifer calf after her first gestation. The calf remained with its dam until 7 months of age, then was placed in isolation until bred. During her first gestation, the second-generation heifer became seropositive for Brucella abortus. She later gave birth to a calf with B abortus infection, as determined by isolation of B abortus biotype 1 from stomach contents, heart blood, lung, and spleen of the calf. The same organism was isolated from the placenta and milk of the dam.
