Resumo: | 北海道東部(道東)の放牧地における牛の小型ピロプラズマ感染りスク低減要因について調査した。道東ではシュルツェマダニ，ヤマトマダニ，ダグラスチマダニが採取され， PCRにより小型ピロプラズマ遺伝子断片が検出され，これらのマダニがベクターとなりうる可能性が考えられた。エゾシカからは多数のマダニが回収され，小型ピロプラズマのベクターを牛の放牧地内へ持ち込むという意味で小型ピロプラズマ感染リスクに関わる動物と考えられた。また，放牧管理体制との関連では，野生動物侵入防止柵の設置，あるいは牧柵周辺の下草刈りが小型ピロプラズマ感染リスク低減に有効である可能性が考えられた。 Factors to decrease risk for Theileria orientalis infection of cattle in pastureland in Eastern Hokkaido were investigated. Ixodes persulcatus，Ixodes ovatus and Haemaphysalis douglusii were collected from the vegetation of the pastureland，and DNA　fragments of T. orientalis were detected from these ticks by using PCR. The results suggested that these tick species may be vectors for T. orientalis in this area. Many ticks have been recovered from wild sika deer，and it was thought that sika deer may be a risk factor of T. orientalis infection by bringing vectors into pastureland with them. Both fence to prevent wild animal invasion into a pastureland and reaping clear away around the pastureland were thought to be effective to decrease risk for T. orientalis infection of cattle.
