Anaerobic bacteria have been recovered from the middle ears of children with AOM, but the data do not support a prominent role for these microorganisms in persons with otitis media, at least in the acute form. They may, however, play a greater role in chronic inflammation of the adenoid bed and biofilm formation. When recovered from ears of children with AOM, the anaerobic pathogen most often is not the sole pathogen cultured.
