Isolates of Candida albicans with sparse filamentation and weak fermentation were isolated from the surface microlayer of the North Sea, but not from subsurface waters. Such atypical isolates may be misidentified by using normal taxonomic procedures.
Alternaria alternata, Aspergillus spp., Bipolaris spicifera, Curvularia lunata, Epicoccum nigrum and Fusarium solani were isolated repeatedly from groups of patients among 96 diagnosed with allergic fungal sinusitis (AFS). Epicoccum nigrum was obtained consistently from four patients, one of whom yielded mycelial masses consistent in morphology with E. nigrum. Fifteen of the predominant fungi recovered from air samples from selected patients' residences included the same species isolated from the mucin of its inhabitants. Air samples from other buildings, whose occupants (non-AFS individuals) complained of poor indoor air quality or of symptoms of the sick building syndrome (SBS), yielded some of the same species involved in AFS. An association of SBS with AFS was not established. Eight of the species implicated in AFS were found to colonize the surfaces of indoor construction and finishing materials at sites other than the residence of the patient. To our knowledge, this is the first report that E. nigrum can colonize nasal sinuses and cause AFS.
