INTRODUCTION
The incidence of canine leptospirosis in Brazil needs to be assessed.
METHODS
The same dogs in southern Brazil were sampled over two years to determine the prevalence, incidence and association of canine leptospirosis with various risk factors.
RESULTS
In 2009, the prevalence was 33 (14.4%) of 228 dogs, with a predominance of serovar Canicola (33.4%). In 2010, 90 dogs were re-evaluated (the remaining dogs were lost to deaths, address changes and donations), and the prevalence was found to be 35 (38.9%) of 90, with the predominant serovar being Icterohaemorrhagiae (51.4%). Moreover, the incidence was 26 of 90 (28.9%), and the disease was statistically associated with age (2009) and street access (2010).
CONCLUSIONS
Our findings revealed instability in the dog population and age to be relevant risk factors for canine leptospirosis.
简介
巴西犬类钩端螺旋体病的发病率尚待评估。
方法
在两年时间里，对巴西南部的同一批犬进行采样，以确定犬类钩端螺旋体病的流行率、发生率以及与各种风险因素的相关性。
结果
2009 年，228 只犬中有 33 只（14.4%）呈阳性，血清型主要为犬型（33.4%）。2010 年，对 90 只犬进行了重新评估（其余犬因死亡、地址变更和捐赠而丢失），发现 90 只犬中有 35 只（38.9%）呈阳性，血清型主要为黄疸出血型（51.4%）。此外，发病率为 90 只中的 26 只（28.9%），该疾病与年龄（2009 年）和街道出入（2010 年）呈统计学相关。
结论
我们的研究结果显示，犬群的不稳定性和年龄是犬类钩端螺旋体病的相关风险因素。
