We report an immunocompromised patient in Alabama, USA, 75 years of age, with relapsing fevers and pancytopenia who had spirochetemia after a tick bite. We identified Borrelia lonestari by using PCR, sequencing, and phylogenetic analysis. Increasing clinical availability of molecular diagnostics might identify B. lonestari as an emerging tickborne pathogen.
我们报告了美国阿拉巴马州的一位免疫功能低下的 75 岁患者,他在被蜱叮咬后出现螺旋体血症、反复发作的发热和全血细胞减少。我们通过 PCR、测序和系统发育分析鉴定了莱姆疏螺旋体。分子诊断学的临床应用日益增加,可能会发现 lonestari 螺旋体是一种新出现的蜱传病原体。
