Stray dogs may be highly exposed to vector-borne pathogens (VBP), including zoonotic agents, and therefore may pose a high risk of spreading infection to other animals and humans. Our study is the first large-scale prevalence study of VBP in stray dogs in Canton Sarajevo, Bosnia and Herzegovina. During the period 2016-2018, a total of 3720 blood samples of stray dogs were screened by the SNAP 4Dx plus test for antibodies against Anaplasma spp., Ehrlichia spp., B. burgdorferi s.l., and D. immitis. The 910 dogs (910/3720, 24.46%) were seropositive for one or more CVBPs. The proportion of seropositive dogs against one, two, or three pathogens was 864 (23.23%), 43 (1.15%), and 3 (0.08%), respectively. The most prevalent canine VBP was Anaplasma spp. (21.59%), followed by B. burgdorferi s.l. (2.47%) and Ehrlichia spp. (1.13%). The lowest prevalence was recorded for D. immitis (0.5%). The number of seropositive dogs older than 1 year was 704 (704/2497, 28.19%), while the number of dogs younger than 1 year was 206 (206/1223, 16.84%). The most common dual coinfection detected was with Anaplasma spp. and B. burgdorferi s.l. (26/3720, 0.7%). The results show that stray dogs are exposed to at least one of these four CVBD pathogens. Since some of these pathogens cause zoonoses, controlling these infections is crucial for both veterinary and public health. These findings highlight the need for continuous serological monitoring of CVBD pathogens in stray dogs due to their risks to animal and human health.
流浪狗可能会高度暴露于媒介传播的病原体（VBP），包括人畜共患病原体，因此可能会对其他动物和人类构成很高的感染传播风险。我们的研究是波斯尼亚和黑塞哥维那萨拉热窝州首次对流浪狗进行的大规模VBP患病率研究。在2016 - 2018年期间，通过SNAP 4Dx plus检测对总共3720份流浪狗的血液样本进行了筛查，以检测针对无形体属、埃立克体属、伯氏疏螺旋体狭义亚种和犬恶丝虫的抗体。910只狗（910/3720，24.46%）对一种或多种食源性人畜共患病原体呈血清阳性。针对一种、两种或三种病原体呈血清阳性的狗的比例分别为864只（23.23%）、43只（1.15%）和3只（0.08%）。最常见的犬类VBP是无形体属（21.59%），其次是伯氏疏螺旋体狭义亚种（2.47%）和埃立克体属（1.13%）。犬恶丝虫的患病率最低（0.5%）。1岁以上血清阳性的狗有704只（704/2497，28.19%），而1岁以下的狗有206只（206/1223，16.84%）。检测到最常见的双重感染是无形体属和伯氏疏螺旋体狭义亚种（26/3720，0.7%）。结果表明，流浪狗暴露于这四种食源性人畜共患病原体中的至少一种。由于其中一些病原体可导致人畜共患病，控制这些感染对兽医和公共卫生都至关重要。这些发现凸显了由于流浪狗对动物和人类健康存在风险，需要对其食源性人畜共患病原体进行持续血清学监测。
