Long-term and large-scale epidemiology of Brucella infection in baleen whales and sperm whales in the western North Pacific and Antarctic Oceans
In a long-term, large-scale serologic study in the western North Pacific Ocean, anti-Brucella antibodies were detected in common minke whales (Balaenoptera acutorostrata) in the 1994–2010 offshore surveys (21%, 285/1353) and in the 2006–2010 Japanese coastal surveys (20%, 86/436), in Bryde’s whales...
