From 2011 to 2017, 4,534 serum samples from 13 wildlife species collected across the US and in one territory (US Virgin Islands) were tested for exposure to Leptospira serovars Bratislava, Canicola, Grippotyphosa, Hardjo, Icterohaemorrhagiae, and Pomona. Of 1,759 canids, 1,043 cervids, 23 small Indian mongooses ( Herpestes auropunctatus), 1,704 raccoons ( Procyon lotor), and five striped skunks ( Mephitis mephitis), 27.0, 44.4, 30.4, 40.8, and 60%, respectively, were antibody positive for any of the six serovars. The most commonly detected serovars across all species were Bratislava and Grippotyphosa. Our results indicate that Leptospira titers are very common in a wide variety of wildlife species. These species may act as important reservoirs in the epidemiological cycle of the pathogen. Additional studies to determine the relationship between serologic evidence and shedding of the pathogen by wildlife are necessary to better understand the risk.
2011年至2017年期间，对在美国本土及一个属地（美属维尔京群岛）采集的13种野生动物的4534份血清样本进行了检测，以确定其是否接触过布拉迪斯拉发、犬型、波摩那、哈焦、出血性黄疸型及黄疸出血型钩端螺旋体血清型。在1759份犬科动物、1043份鹿科动物、23份小印度猫鼬（食蟹獴）、1704份浣熊及5份条纹臭鼬的样本中，分别有27.0%、44.4%、30.4%、40.8%和60%的样本对六种血清型中的任意一种呈抗体阳性。在所有物种中最常检测到的血清型是布拉迪斯拉发和波摩那。我们的结果表明，钩端螺旋体滴度在多种野生动物物种中非常普遍。这些物种可能在该病原体的流行病学循环中充当重要的宿主。有必要开展进一步研究以确定血清学证据与野生动物病原体传播之间的关系，从而更好地了解相关风险。
