Abstract

The lungs of Hokkaido brown bears (Ursus arctos yesoensis) collected between August 2006 and August 2009 were histologically examined. Only one bear found dead in Yakumo had a small number of Hepatozoon sp. schizonts; whereas, none of the 24 bears killed in Nakasatsunai, Urahoro, Rausu, and Kitami were infected with Hepatozoon sp.
