Serum samples (n = 457) from wolves (Canis lupus) in northern Minnesota were collected from 1972 through 1986 and were tested for antibodies against Leptospira interrogans using a microtiter agglutination test. Twelve serovars included in the study were: australis, autumnalis, ballum, bataviae, bratislava, canicola, copenhageni, grippotyphosa, hardjo, pomona, pyrogenes, and tarassovi. Fifty-two (11%) sera had antibody titers of greater than or equal to 1:50 against one or more serovars of L. interrogans. The seroprevalence of different serovars in decreasing order was: grippotyphosa, bratislava, autumnalis, canicola, pomona, ballum, pyrogenes, hardjo, and copenhageni. No antibodies were found against australis, bataviae, and tarassovi. These results indicate that L. interrogans infection may occur in wolves of Minnesota.
1972年至1986年期间，从明尼苏达州北部的狼（犬属狼种）身上采集了血清样本（n = 457），并使用微量滴定凝集试验检测了针对问号钩端螺旋体的抗体。该研究中包含的12个血清型为：澳洲型、秋季型、拜伦型、巴达维亚型、布拉迪斯拉发型、犬型、哥本哈根型、爪哇型、哈焦型、波摩那型、热解型和塔拉索夫型。52份（11%）血清针对一种或多种问号钩端螺旋体血清型的抗体效价大于或等于1:50。不同血清型的血清阳性率从高到低依次为：爪哇型、布拉迪斯拉发型、秋季型、犬型、波摩那型拜伦型、热解型、哈焦型和哥本哈根型。未发现针对澳洲型、巴达维亚型和塔拉索夫型的抗体。这些结果表明，明尼苏达州的狼可能感染问号钩端螺旋体。
