title: Cross-recognition of aspergillus galactomannan caused by Listeria monocytogenes infection.
abstract: We report a case of Listeria monocytogenes bacteremia in a leukemic patient having a positive assay for aspergillus galactomannan (GM), although no evidence of aspergillosis was found. Supernatant obtained from L. monocytogenes strain suspension was reactive with GM-assay. L. monocytogenes produces a soluble antigen that is cross-reactive with Aspergillus GM.
