This is the first case of Spiromastigoides asexualis human infection, and it notably gave a false-positive Blastomyces DNA probe laboratory result. We further investigated other Spiromastigoides isolates as a cause of false-positive testing results, their phylogenetic relationship, and their susceptibility profiles to clinically available antifungal agents. Other S. asexualis isolates also resulted in positive Blastomyces DNA probe results, while Spiromastigoides species other than S. asexualis did not.

无性螺旋体：作为假阳性芽生菌 DNA 探针测试原因的系统发育分析和评估。

这是人类感染无性螺旋体的第一例，特别是给出了假阳性芽生菌DNA 探针实验室结果。我们进一步调查了其他螺旋体分离株作为假阳性检测结果的原因、它们的系统发育关系以及它们对临床可用抗真菌药物的敏感性特征。其他S. asexualis分离株也产生阳性芽生菌DNA 探针结果，而S. asexualis以外的Spiromastigoides物种则没有。
