| Outline of Final Research Achievements |
The diagnosis of mucormycosis was made by the identification of organism in the histopathology with culture confirmation. However, culture often yields no growth, and histopathological identification of organism with typical of Mucorales is sometimes difficult. Therefore, the reliable new diagnostic tool is expected. Secreted and cell-surface molecules are as target antigens for diagnostic tools. The signal sequence trap (SST) is a strategy to identify signal sequence containing cDNAs that encode secreted and cell-surface proteins. We constructed a SST c DNA library from RNA extraction from the clinical isolate Rhizopus oryzae. The ELISA kit to detect the target antigen was made and evaluated. The antigen A was also detected in R. oryzae infected mice sera. The 23kDa of the hypothetical protein, Antigen A, is a potential novel diagnostic maker in mucormycosis.
