The Novel Monoclonal IgG<sub>1</sub>-Antibody AB90-E8 as a Diagnostic Tool to Rapidly Distinguish <i>Aspergillus fumigatus</i> from Other Human Pathogenic <i>Aspergillus</i> Species
In most cases, invasive aspergillosis (IA) is caused by <i>A. fumigatus</i>, though infections with other <i>Aspergillus</i> spp. with lower susceptibilities to amphotericin B (AmB) gain ground. <i>A. terreus</i>, for instance, is the second leading cause of IA in...

description | In most cases, invasive aspergillosis (IA) is caused by <i>A. fumigatus</i>, though infections with other <i>Aspergillus</i> spp. with lower susceptibilities to amphotericin B (AmB) gain ground. <i>A. terreus</i>, for instance, is the second leading cause of IA in humans and of serious concern because of its high propensity to disseminate and its in vitro and in vivo resistance to AmB. An early differentiation between <i>A. fumigatus</i> and <i>non-A. fumigatus</i> infections could swiftly recognize a potentially ineffective treatment with AmB and lead to the lifesaving change to a more appropriate drug regime in high-risk patients. In this study, we present the characteristics of the monoclonal IgG<sub>1</sub>-antibody AB90-E8 that specifically recognizes a surface antigen of <i>A. fumigatus</i> and the closely related, but not human pathogenic <i>A. fischeri</i>. We show immunostainings on fresh frozen sections as well as on incipient mycelium picked from agar plates with tweezers or by using the expeditious tape mount technique. All three methods have a time advantage over the common procedures currently used in the routine diagnosis of IA and outline the potential of AB90-E8 as a rapid diagnostic tool. |
