Serum samples from 153 woodchucks (Marmota monax) from Tompkins County, New York, obtained in 1976 and 1977, were examined by plate agglutination tests for antibodies against five Leptospira antigens. Fourteen sera showed significant titers against either L. hardjo, L. icterohemorrhagiae and/or L. pomona. Reactions against L. hardjo were the most frequent. Woodchucks collected from two dairy farms with histories of bovine leptospirosis did not have a greater prevalence of antibodies than woodchucks collected from other locations. Each of two woodchucks experimentally-inoculated with L. hardjo developed titers to L. hardjo. Maximum titers occurred approximately 30 days post-inoculation. L. hardjo was not observed in urine specimens of these animals.
1976年和1977年从纽约汤普金斯县采集的153份土拨鼠（Marmota monax）血清样本，通过平板凝集试验检测了针对五种钩端螺旋体抗原的抗体。14份血清对哈氏钩端螺旋体、出血性黄疸钩端螺旋体和/或波摩那钩端螺旋体呈现显著滴度。针对哈氏钩端螺旋体的反应最为常见。从两个有牛钩端螺旋体病史的奶牛场采集的土拨鼠，其抗体流行率并不高于从其他地点采集的土拨鼠。两只经实验接种哈氏钩端螺旋体的土拨鼠均产生了针对哈氏钩端螺旋体的滴度。最高滴度出现在接种后约30天。在这些动物的尿液样本中未检测到哈氏钩端螺旋体。
