We identified the presence of Toxoplasma gondii in ticks and their host dogs, and assess the potential role of ticks as reservoirs for this pathogen. A total of 1,230 feeding ticks were collected from 340 dogs. The tick species identified included Haemaphysalis longicornis, H. flava, and Ixodes nipponensis. Detection of the T. gondii B1 gene occurred in 2 dogs (0.6%) and 4 tick pools (0.9%). Genotyping confirmed the presence of the I/III genotype. This study is the first to report the molecular detection of T. gondii in both canine ticks and their hosts. Our findings offer important insights into the dynamics of T. gondii transmission between vectors and their hosts.
我们在蜱虫及其宿主犬类中发现了刚地弓形虫的存在，并评估了蜱虫作为该病原体储存宿主的潜在作用。共从340只犬类身上采集了1230只正在吸血的蜱虫。鉴定出的蜱虫种类包括长角血蜱、微小牛蜱和日本硬蜱。在2只犬（0.6%）和4个蜱虫样本池（0.9%）中检测到了刚地弓形虫B1基因。基因分型证实存在I/III基因型。本研究首次报告了在犬蜱及其宿主中对刚地弓形虫进行分子检测的情况。我们的研究结果为弓形虫在媒介及其宿主之间的传播动态提供了重要见解。
