Novel strains of Brucella recently have been discovered in marine mammals. To investigate Brucella exposure and infection in a general population of cetaceans, blood and tissue samples were collected and analyzed from wild harbor porpoises (Phocoena phocoena) incidentally caught in fishing gear in the Bay of Fundy, Canada. Two of 170 (1.2%) animals had detectable antibodies against Brucella, but no organisms were isolated from genital swabs or tissues from 22 and 8 porpoises, respectively. Genetic analysis of inflamed testes from 20 animals yielded no amplification of Brucella DNA. This is the first evidence of exposure to Brucella in porpoises from the western North Atlantic, and the prevalence is much lower than documented for conspecifics from the eastern North Atlantic.
最近在海洋哺乳动物中发现了新型布鲁氏菌菌株。为了调查鲸类动物总体中的布鲁氏菌暴露和感染情况，从加拿大芬迪湾意外被渔具捕获的野生港湾鼠海豚（Phocoena phocoena）身上采集了血液和组织样本并进行分析。170只动物中有2只（1.2%）检测到抗布鲁氏菌抗体，但分别从22只和8只鼠海豚的生殖器拭子或组织中未分离出病原体。对20只动物发炎睾丸的基因分析未扩增出布鲁氏菌DNA。这是北大西洋西部鼠海豚暴露于布鲁氏菌的首个证据，其患病率远低于北大西洋东部同物种的记录。
