Epidemiologic studies have linked interactions with cats as a risk factor for human leptospirosis, but serosurveys of feline Leptospira spp. infection are scarce in the veterinary literature. The objective of this study was to conduct a serosurvey of Leptospira spp. infection in cats presenting to an eastern Canadian veterinary teaching hospital (VTH). All serum samples collected from cats presented to the VTH were tested by the microscopic agglutination test (MAT) for the Leptospira serovars Canicola, Grippotyphosa, Icterohaemorrhagiae, Bratislava, Pomona, and Autumnalis. Ten of 40 cats [25%; 95% confidence interval (CI): 12.7% to 41.2%] tested had positive antibody titers (≥ 1:100). All 10 cats with positive titers were positive for Bratislava and 2 were also positive for Autumnalis. This high incidence of seropositivity for Leptospira spp. may suggest that the disease could be of more clinical importance than previously recognized.
流行病学研究已将与猫的接触作为人类钩端螺旋体病的一个风险因素，但兽医文献中关于猫感染钩端螺旋体属的血清学调查却很少。本研究的目的是对一家加拿大东部兽医教学医院（VTH）收治的猫进行钩端螺旋体属感染的血清学调查。对送至VTH的猫采集的所有血清样本，通过显微镜凝集试验（MAT）检测钩端螺旋体血清型犬型、爪哇型、出血性黄疸型、布拉迪斯拉发型、波摩那型和秋季热型。40只接受检测的猫中有10只（25%；95%置信区间[CI]：12.7%至41.2%）抗体滴度呈阳性（≥1:100）。所有10只滴度呈阳性的猫对布拉迪斯拉发型均呈阳性，2只对秋季热型也呈阳性。钩端螺旋体属血清阳性的高发生率可能表明，该病的临床重要性可能比之前认为的更高。
