项目摘要
The diagnosis of mucormycosis relies upon the identification of organisms in tissue by histopathology with culture confirmation. However, culture often yields no growth, and histopathologic identification of an organism with a structure typical of Mucorales may provide the only evidence of infection. A clinician must think of this entity in the appropriate clinical setting and pursue invasive testing in order to establish a diagnosis as early as possible. Therefore, new early detection methods are required. We used a novel signal sequence trap methods to select protein antigen from Rhizopus oryzae. Two unknown proteins with signal sequences, antigen A (26kDa, hypothetical protein) and B (46kDa, hypothetical protein) were selected as candidates. We made ELISA kit to detect antigen A. The antigen A was detected in the culture supernatant of R. oryzae、R microspores、R microspores var. rhizopodiformis. The antigen was also detected in the serum form Rhizopus infected mice.
毛霉菌病的诊断依赖于通过组织病理学和培养确认来鉴定组织中的微生物。然而,培养通常不会产生生长,并且具有毛霉目典型结构的生物体的组织病理学鉴定可能提供感染的唯一证据。临床医生必须在适当的临床环境中考虑该实体并进行侵入性检测,以便尽早做出诊断。因此,需要新的早期检测方法。我们使用一种新颖的信号序列捕获方法从米根霉中选择蛋白质抗原。选择两种具有信号序列的未知蛋白,抗原A(26kDa,假设蛋白)和B(46kDa,假设蛋白)作为候选蛋白。我们制作了检测抗原A的ELISA试剂盒。在米根霉、R小孢子、R小孢子变种的培养上清液中检测到了抗原A。根足形。在根霉感染小鼠的血清中也检测到了该抗原。
