Blood, kidney and tick samples were obtained from 18 hunter-killed black bears (Ursus americanus) from three sites in northern Wisconsin. A Borrelia sp., morphologically and antigenically similar to Borrelia burgdorferi, was isolated from the blood of two of the animals, and from the kidney of a third. Ixodes dammini and Dermacentor variabilis were found on the bears. This is the first report of borreliosis in the Ursidae, and of the primary vector of Lyme disease, I. dammini, from this host.
从威斯康星州北部三个地点的18只被猎人捕杀的黑熊（美洲黑熊）身上采集了血液、肾脏和蜱虫样本。从其中两只动物的血液以及第三只动物的肾脏中分离出一种形态和抗原性与伯氏疏螺旋体相似的疏螺旋体。在这些熊身上发现了达氏硬蜱和变异革蜱。这是熊科动物感染莱姆病的首例报告，也是这种宿主身上首次发现莱姆病的主要传播媒介——达氏硬蜱。
