The TaqMan real-time PCR assay was developed from the Blastomyces dermatitidis BAD1 gene promoter. The assay identified all haplotypes of B. dermatitidis and five of six positive paraffin-embedded tissues. The assay sensitivity threshold was 1 pg genomic DNA of the mold form and 2 CFU of the yeast form of B. dermatitidis. No cross-reactivity was observed against other fungal DNA. The assay allowed rapid (5-h) identification of B. dermatitidis from culture and from clinical specimens.
TaqMan 实时 PCR 检测法是从皮炎芽生菌 BAD1 基因启动子开发而来的。该检测法可识别皮炎芽生菌的所有单倍型和 6 份石蜡包埋组织中的 5 份阳性样本。检测法的灵敏度阈值为 1pg 霉菌形式的基因组 DNA 和 2CFU 的酵母形式的皮炎芽生菌。未观察到与其他真菌 DNA 的交叉反应。该检测法可在 5 小时内快速鉴定培养物和临床标本中的皮炎芽生菌。
