title: Fungi from otitis media of agricultural field workers.
abstract: Twenty four fungi were isolated from ear wax or otitis media of agricultural field workers, of which 18 are being reported for the first time from India. Direct observation, revealed the presence of hyphal fragments, spores of Alternaria, Bipolaris, conidial head of Aspergillus, smut teliospores and pollen. Spores of only four fungi, Alternaria humicola, Aspergillus niveus, Bipolaris spicifera and Fusarium moniliforme germinated in otitis media at 37 degrees C, and their germination was affected by relative humidity. Alternaria humicola and Aspergillus niveus appeared to be the causative agents of otomycosis, and otitis media is fungistatic in nature.
