Ticks are obligate blood-sucking ectoparasites that infect a wide range of animals and humans, causing a variety of both human and animal diseases around the world. Ixodes nipponensis is the most commonly reported tick in Korea and Japan, but it is very rare in China. In this study, six I. nipponensis samples were collected from three black goats in Hunan province, China. Ticks identified morphologically as I. nipponensis were then examined by PCR with two different molecular markers: mitochondrial cox1 and the second internal transcribed spacer of ribosomal DNA genes. Sequence comparison and phylogenetic analysis of the cox1 sequences confirmed that all of the examined hard Ixodes ticks represented I. nipponensis. This finding indicates a potential risk of zoonotic I. nipponensis infection in humans and animals in China. To our knowledge, this is the first report documenting the occurrence of I. nipponensis infection in goats in China.
蜱是专性吸血的体外寄生虫，可感染多种动物和人类，在全球范围内引发多种人畜疾病。日本硬蜱是韩国和日本报道最为常见的蜱，但在中国非常罕见。在本研究中，从中国湖南省的三只黑山羊身上采集了6只日本硬蜱样本。随后，利用两种不同的分子标记（线粒体细胞色素c氧化酶亚基1（cox1）和核糖体DNA基因的第二内部转录间隔区）通过PCR对形态学鉴定为日本硬蜱的蜱进行检测。cox1序列的序列比较和系统发育分析证实，所有检测的硬蜱均为日本硬蜱。这一发现表明中国人和动物存在感染日本硬蜱的潜在风险。据我们所知，这是中国首次报道山羊感染日本硬蜱的病例。
