Rodents (n = 358) were trapped from 6 locations in Arizona, including 2 dairies, 2 swine raising operations, and 2 areas where domestic animal access was limited. Isolates of Leptospira interrogans serovar ballum were obtained from 3 house mice (Mus musculus) trapped in dairies. Leptospira were seen in silver-stained kidney sections of 10.4% of the rodents. The usefulness of serologic data in detecting leptospiral infection in these rodents was uncertain because so few animals yielded isolates that valid comparisons of culture positives to serologic positives were not possible. Titers greater than or equal to 1:160 were obtained to serovars autumnalis, ballum, bratislava, canicola, grippotyphosa, hardjo, icterohaemorrhagiae, and pomona. Nearly 60% of the rodents had microscopic lesions in kidneys, including 20 of 34 (59%) of those in which leptospira were seen.
从亚利桑那州的6个地点捕获了358只啮齿动物，包括2个奶牛场、2个养猪场以及2个家畜活动受限的区域。从捕获于奶牛场的3只家鼠（小家鼠）中分离出了问号钩端螺旋体拜伦血清型。在10.4%的啮齿动物经银染的肾脏切片中发现了钩端螺旋体。血清学数据在检测这些啮齿动物钩端螺旋体感染中的作用尚不确定，因为分离出病原体的动物太少，无法对培养阳性与血清学阳性进行有效比较。检测到秋季热、拜伦、布拉迪斯拉发、犬型、爪哇热、哈焦、出血性黄疸、波摩那等血清型的滴度大于或等于1:160。近60%的啮齿动物肾脏有显微病变，其中在34只发现有钩端螺旋体的动物中有20只（59%）出现了肾脏显微病变。
