从1995年1月和2月在Pangnirtung（加拿大巴芬岛）附近采集的4只环海豹（Phoca hispida）和1996年3月在莫达伦群岛（加拿大圣劳伦斯湾）附近采集的1只格陵兰海豹（Phoca groenlandica）的淋巴结中分离出一种新型布鲁氏菌。5株菌株的细菌学特征相同。菌落为典型的布鲁氏菌，但比传统菌种多花2 ~ 5天出现在初级分离培养基上。生物分型结果与任何已知的布鲁氏菌生物变种都不匹配，但与先前报道的从居住在北半球其他地区的海洋哺乳动物中分离出的布鲁氏菌属相似。这是加拿大海洋哺乳动物中首次确认的布鲁氏菌病报告，也是斑海豹和竖琴海豹中首次报告这种生物。
A novel Brucella sp, was isolated from lymph nodes of four ringed seals (Phoca hispida) collected near Pangnirtung (Baffin Island, Canada) in January and February 1995 and in one harp seal (Phoca groenlandica) collected near the Magdalen Islands (Gulf of St. Lawrence, Canada) in March 1996. Bacteriological characteristics were the same for all five isolates. The colonies were typical of Brucella spp., but took 2 to 5 days longer than the traditional species to appear on primary isolation media. Biotyping results did not match any of the known biovars of Brucella, but were similar to isolates of the genus Brucella previously reported from marine mammals inhabiting other areas of the northern hemisphere. This is the first confirmed report of brucellosis in marine mammals from Canada, and the first report of this organism in ringed and harp seals.
