Ticks account for an extensive range of health and welfare issues in horses. In addition, tick‐borne pathogens (TBPs) limit global animal trading and equine sporting events. Here, we assess the prevalence, co‐infectivity and risk factors of TBPs in horse ticks in Korea. A total of 245 hard ticks, including 103 male and 142 female adults, were obtained from horses on Jeju Island during the spring to autumn seasons of 2013–2019. All collected ticks were identified as adult Haemaphysalis longicornis. We screened and analyzed each tick for the presence of several TBPs by polymerase chain reaction (PCR) analysis. Among the 245 ticks, we detected genes for three TBPs, Candidatus Rickettsia longicornii (22.9%), Ehrlichia canis (0.4%) and Theileria luwenshuni (0.4%), while Anaplasma spp. was not detected. TBPs were most prevalent in ticks harvested during the autumn season, and more abundant in the female than male adults. This is the first report of the genera Ehrlichia, Rickettsia and Theileria in horse ticks in Korea. TBPs in horse ticks are likely a reservoir for zoonotic transmission to other animals, including humans. Our findings demonstrate the need for further understanding of the prevalence and epidemiology of TBPs in wild and domestic animals.

韩国s虫传播的carried携带的tick传播病原菌的多样性和基因型分析
壁虱是马匹中广泛的健康和福利问题。此外，tick传播的病原体（TBP）限制了全球动物贸易和马运动项目。在这里，我们评估了韩国马蹄中TBP的患病率，共感染性和危险因素。在2013 - 2019年春季至秋季期间，从济州岛的马匹中获得了总共245个硬hard，包括成年的男性和142个雌性。所有采集到的s均被鉴定为成年的血ema。我们通过聚合酶链反应（PCR）分析筛选并分析了每个刻度是否存在几个TBP。其中245个蜱，我们检测到的基因三个时限计划，暂定立克longicornii（22.9％），犬埃立克体（0.4％）和泰勒虫（Theileria luwenshuni）（0.4％），而无浆菌（Anaplasma spp。）。未检测到。TBPs在秋季收获的tick中最普遍，在雌性中比雄性成年时更为丰富。这是韩国hr虫中埃里希氏菌，立克次体和泰勒虫属的首次报道。马tick中的TBP可能是人畜共患病传染给其他动物（包括人）的储存库。我们的发现表明，需要进一步了解野生和家养动物中TBP的患病率和流行病学。
