Abstract
In order to improve current culture-based monitoring techniques for Aspergillus versicolor and other fungi in general, our laboratory is developing species-specific monoclonal antibody (mAb)-based immunoassay techniques. In this study we attempted to enhance the production of mAbs specific for A. versicolor by immunizing mice with pre-formed immune complexes to block epitopes of spores known to be cross-reactive with other fungi. We found that immunization with immune complexes did not enhance the production of A. versicolor-specific mAbs. While the antibody reactivity to related Aspergillus and Penicillium species was reduced, the response to other fungi was enhanced. The patterns of cross-reactivity among the 50 tested fungal species not only demonstrate that phylogenetically distant fungi share common epitopes but also that different fungi express a given cross-reactive epitope in variable amounts on a per spore basis.
