Abstract

Brucella species infecting marine mammals was first reported in 1994 and in the years since has been documented in various species of pinnipeds and cetaceans. While these reports have included species that inhabit Arctic waters, the few available studies on bearded seals Erignathus barbatus have failed to detect Brucella infection to date. We report the first isolation of Brucella pinnipedialis from a bearded seal. The isolate was recovered from the mesenteric lymph node of a bearded seal that stranded in Scotland and typed as ST24, a sequence type associated typically with pinnipeds. Furthermore, serological studies of free-ranging bearded seals in their native waters detected antibodies to Brucella in seals from the Chukchi Sea (1990-2011; 19%) and Svalbard (1995-2007; 8%), whereas no antibodies were detected in bearded seals from the Bering Sea or Bering Strait or from captive bearded seals.

摘要

1994年首次报道了感染海洋哺乳动物的布鲁氏菌物种，自那以后的数年里，在各种鳍足类动物和鲸类动物中都有相关记录。虽然这些报告涵盖了栖息在北极水域的物种，但迄今为止，针对髯海豹（Erignathus barbatus）的少数现有研究均未检测到布鲁氏菌感染。我们报告了首次从髯海豹中分离出海豹布鲁氏菌。该分离株是从一头搁浅在苏格兰的髯海豹的肠系膜淋巴结中分离得到的，其分型为ST24，这是一种通常与鳍足类动物相关的序列型。此外，对在其原生水域自由活动的髯海豹进行的血清学研究发现，楚科奇海（1990 - 2011年；19%）和斯瓦尔巴群岛（1995 - 2007年；8%）的髯海豹体内检测到了布鲁氏菌抗体，而白令海或白令海峡的髯海豹以及圈养髯海豹体内未检测到抗体。
