The occurrence of tick-borne infectious diseases, including zoonotic babesiosis, has become a serious concern in recent years. In this study, we detected Babesia spp. using polymerase chain reaction (PCR) amplification of the 18S rRNA of the parasites isolated from ixodid ticks collected from small mammals in the Republic of Korea (ROK). Sequence analysis of the PCR amplicon revealed the presence of B. duncani, B. venatorum, B. capreoli/divergens, and, the most prevalent, B. microti in the ticks. The molecular phylogenetic analysis showed that the four species-specific18S rRNA sequences clustered in four distinct clades. This is the first study to provide molecular evidence for the presence of zoonotic Babesia spp. other than B. microti in ticks in the ROK.
近年来,蜱传传染病的发生,包括人畜共患的巴贝斯虫病,已成为一个严重的问题。在这项研究中,我们使用聚合酶链反应(PCR)扩增寄生虫的 18S rRNA,从韩国(ROK)从小型哺乳动物中采集的硬蜱中检测到巴贝斯虫属。PCR 扩增子的序列分析显示,蜱中有 B. duncani、B. venatorum、B. capreoli/divergens 和最常见的 B. microti。分子系统发育分析表明,这四个种特异性 18S rRNA 序列聚集在四个不同的分支中。这是首次在 ROK 的蜱中提供除 B. microti 以外的人畜共患巴贝斯虫属的分子证据。
