MOLECULAR IDENTIFICATION OF ASPERGILLUS SPECIES

摘要

Novel techniques for the detection of Aspergillus in samples are disclosed. These techniques relate to PCR amplification and/or detection of Aspergillus ITS1 rDNA sequences, and the identification of particular species of Aspergillus by detecting differences in the ITS1-V1, ITS-V2, ITS-V3, ITS-V4, and ITS-V5 nucleic acid sequences of Aspergillus. The highly variable regions of the ITS1 rDNA sequences are particularly useful in distinguishing, for example, Aspergillus clavatus, Aspergillus granulosus, Aspergillus sydowii, Aspergillus flavipes, Aspergillus restrictus, Aspergillus versicolor, Aspergillus wentii, and Aspergillus chevalieri. In particular embodiments, the sequence differences are also able to distinguish among variants of particular species, such as Aspergillus granulosus CBS 119.5A, Aspergillus granulosus strain NRRL 1932, Aspergillus sydowii strain NRRL 250, Aspergillus sydowii strain NRRL 4768, Aspergillus sydowii strain CUHI, Aspergillus sydowii strain CUH2, Aspergillus sydowii strain CUH7, and Aspergillus sydowii strain CUH8.
