African tick-bite fever (ATBF) caused by Rickettsia africae is a frequent cause of fever in returned travelers. Here, we used eschar swabs and/or eschar crust samples for the molecular diagnosis of ATBF in returned travelers. In 4 of 5 patients returning from South Africa, including 3 with negative serology, R. africae was identified by molecular tools targeting 2 different genes. The findings of this study highlight the usefulness of eschar swabs and/or eschar crust samples for the diagnosis of R. africae infection.
非洲蜱咬热（ATBF）是由非洲立克次体引起的，是返回旅行者发热的常见原因。在这里，我们使用焦痂拭子和/或焦痂痂皮样本对来自返回旅行者的 ATBF 进行分子诊断。在从南非返回的 5 名患者中的 4 名中，包括 3 名血清学阴性的患者，通过针对 2 个不同基因的分子工具鉴定出了非洲立克次体。本研究的结果强调了焦痂拭子和/或焦痂痂皮样本对诊断非洲立克次体感染的有用性。
