Abstract

Observations on 2 bulls from a brucella-infected property are reported. Bull 1 gave serological reactions to Br. abortus in both the SAT and CFT from day 0 to day 141. Br. abortus was not recovered from semen and the bull remained clinically normal. The serological status of bull 2 changed from negative to positive to negative over a 203 day period and remained negative for a further 74 days. Semen agglutinins were only detected on one occasion (20 iu). The first clinical sign observed was epididymitis followed by orchitis, which became apparent on day 122. Br. abortus was not recovered from semen but at autopsy, on day 363, Br. abortus biotype 1 was isolated from the right seminal vesicle and ampulla. The histology of the lesion is described. The literature relating to Br. abortus infection in the bull is discussed. Recommendations are made regarding the diagnosis of Br. abortus infection in bulls.

摘要

报告了对来自一个感染布鲁氏菌养殖场的2头公牛的观察情况。公牛1从第0天到第141天，在血清凝集试验（SAT）和补体结合试验（CFT）中均对流产布鲁氏菌产生血清学反应。精液中未分离出流产布鲁氏菌，且该公牛临床状况正常。公牛2的血清学状态在203天内从阴性变为阳性再变为阴性，并在接下来的74天内保持阴性。仅在一次检测中检测到精液凝集素（20国际单位）。观察到的首个临床症状是附睾炎，随后是睾丸炎，在第122天变得明显。精液中未分离出流产布鲁氏菌，但在第363天尸检时，从右侧精囊和壶腹分离出了1型流产布鲁氏菌。描述了病变的组织学情况。讨论了与公牛感染流产布鲁氏菌相关的文献。就公牛流产布鲁氏菌感染的诊断提出了建议。
