Research Abstract

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.
