We report a case of tick-borne relapsing fever caused by Borrelia persica in a traveler returning to Switzerland from central Asia. After the disease was diagnosed by blood smear microscopy, the causative Borrelia species was confirmed by shotgun metagenomics sequencing. PCR and sequencing techniques provide highly sensitive diagnostic tools superior to microscopy.
我们报告了一例由从中亚返回瑞士的旅行者感染的波斯尼亚螺旋体引起的蜱传回归热病例。在通过血涂片显微镜检查诊断该病后,通过鸟枪法宏基因组测序确定了致病的螺旋体种类。PCR 和测序技术提供了比显微镜更敏感的诊断工具。
