Canine vector-borne diseases (CVBDs) comprise a group of infectious diseases caused by a wide range of pathogens transmitted by arthropod vectors. Clinical signs commonly involve symptoms such as fever, anorexia, weight loss, blood disorders, hepatosplenomegaly, and others that can lead to death in dogs with comorbidities. Some pathogens responsible for CVBDs constitute a serious threat to human health due to their zoonotic transmission. This study aimed to determine the prevalence of zoonotic vector-borne diseases (, , , , and ) in domestic Sardinian dogs with and without clinical signs of these pathogens. Blood serum samples were collected from 142 dogs and examined through serological analysis. Clinical signs suggestive of these pathogens were also evaluated. The results obtained showed that 33 (33/140; 23.6%), 22 (22/134; 16.4%), 14 (14/142; 9.9%), 20 (20/66; 30.3%), and 26 (26/108; 24.1%) dogs were seropositive for sp., sp., sp., sp., and sp. antibodies, respectively. Among these dogs, 12 dogs presented with at least one clinical sign (8.5%), while 18 (12.7%) showed more than two symptoms at the same time. Furthermore, among the asymptomatic dogs (93/142; 65.5%), 13% ( = 12) tested positive for , 12% ( = 11) tested positive for , 9% ( = 8) tested positive for , 12% ( = 11) tested positive for , and 19% ( = 18) tested positive for . This survey represents the first study assessing different canine vector-borne pathogens in dogs from North Sardinia. Since the pathogens detected here represent emerging zoonotic diseases, these results highlight the need to undertake further studies to increase the knowledge of these under-reported vector-borne pathogens in Sardinia.
犬媒传播疾病（CVBDs）是由节肢动物媒介传播的多种病原体引起的一组传染病。临床症状通常包括发热、厌食、体重减轻、血液疾病、肝脾肿大等，这些症状可导致患有合并症的犬死亡。一些导致CVBDs的病原体由于其人畜共患传播，对人类健康构成严重威胁。本研究旨在确定有和没有这些病原体临床症状的撒丁岛家养犬中，人畜共患媒介传播疾病（、、、和）的流行情况。从142只犬采集血清样本，并通过血清学分析进行检测。还评估了提示这些病原体的临床症状。获得的结果显示，分别有33只（33/140；23.6%）、22只（22/134；16.4%）、14只（14/142；9.9%）、20只（20/66；30.3%）和26只（26/108；24.1%）犬对sp.、sp.、sp.、sp.和sp.抗体呈血清阳性。在这些犬中，12只犬出现至少一种临床症状（8.5%），而18只（12.7%）同时出现两种以上症状。此外，在无症状犬（93/142；65.5%）中，13%（=12）对检测呈阳性，12%（=11）对检测呈阳性，9%（=8）对检测呈阳性，12%（=11）对检测呈阳性，19%（=18）对检测呈阳性。这项调查是评估撒丁岛北部犬中不同犬媒传播病原体的第一项研究。由于此处检测到的病原体代表新兴的人畜共患疾病，这些结果凸显了开展进一步研究以增加对撒丁岛这些报告不足的媒介传播病原体认识的必要性。
