Canine vector-borne diseases (CVBDs) pose a global threat to both canine and public health. This study evaluates the prevalence of spp., spp., sensu lato (s.l.), , and in domestic dogs in Liguria, north-west Italy, a region where data were lacking. From 2013 to 2023, 8584 blood samples from shelter (74%) and owned dogs (26%) were submitted to the (IZSPLV) for serological testing (indirect immunofluorescence and/or rapid immunochromatographic tests). Overall, 18.8% (95% CI: 18.0-19.7) of the dogs tested positive for at least one pathogen, with positivity against antigen being the most frequently recorded (24.4%, 95% CI: 23.3-25.5). Lower prevalence levels were observed for spp. (1.82%, 95% CI: 1.47-2.23), spp., (1.25%, 95% CI: 0.97-1.60), s.l. (0.22%, 95% CI: 0.11-0.39), and (0.84%, 95% CI: 0.65-1.06). Positive cases for all pathogens increased over time, with prevalence differing significantly between owned and shelter dogs. Topographical factors, land use, and monthly relative humidity appeared to influence the positivity in the dogs. These results update the epidemiology of the investigated CVBDs in Liguria, indicating a widespread exposure to spp. among local dogs.
犬媒传播疾病（CVBDs）对犬类和公众健康构成全球威胁。本研究评估了意大利西北部利古里亚地区家犬中 spp.、 spp.、 广义（s.l.）、 以及 的流行情况，该地区此前缺乏相关数据。2013年至2023年期间，来自收容所（74%）和家养犬（26%）的8584份血样被提交至利古里亚兽医卫生与食品安全研究所（IZSPLV）进行血清学检测（间接免疫荧光和/或快速免疫层析检测）。总体而言，18.8%（95%置信区间：18.0 - 19.7）的犬至少对一种病原体检测呈阳性，其中针对 抗原的阳性率最高（24.4%，95%置信区间：23.3 - 25.5）。观察到 spp. 的流行率较低（1.82%，95%置信区间：1.47 - 2.23）， spp. 为（1.25%，95%置信区间：0.97 - 1.60）， 广义（s.l.）为（0.22%，95%置信区间：0.11 - 0.39）， 为（0.84%，95%置信区间：0.65 - 1.06）。所有病原体的阳性病例随时间增加，家养犬和收容所犬的流行率存在显著差异。地形因素、土地利用和月相对湿度似乎影响犬类的阳性率。这些结果更新了利古里亚地区所调查的CVBDs的流行病学情况，表明当地犬类普遍接触 spp.。
