| Outline of Final Research Achievements |
The purpose of this study is to develop a new method to identify and discriminate Aspergillus fumigatus and relating species (Aspergillus section Fumigati) by mass spectrometry. To make a reliable biomarker list, we have characterized ribosomal subunit proteins of five species of genome sequenced strains of A. fumigatus and relating fungus by mass spectrometry, and verified the translated amino acid sequences registered in public databases. Based on the profiles of the ribosomal protein biomarkers, a phylogenetic tree of clinical and environmental fungal samples could be constructed. These results demonstrated the developed method would be a sufficiently high-throughput technique for rapid discrimination of closely related Aspergillus species.
